#1 Plumber San Tan Valley, AZ
A burst pipe, a dead heater, a drain that won’t quit — call the emergency plumber San Tan Valley, AZ trusts: (866) 471-4088, 24/7. Hidden leaks, slab leaks, sewers — one live dispatcher for all of it.
Live dispatcher 24/7 · Upfront flat-rate price before any work · Serving all of San Tan Valley
San Tan Valley became a town on September 17, 2025 — the largest incorporation in Arizona history, with 123,000+ residents overnight. That one fact explains more about the plumbing here than any fixture catalog: a place this new is still growing, still building, still arguing about who provides what. The water can come from EPCOR or from the Town of Queen Creek depending on your street, the sewers carry the memory of the Johnson Utilities era, and the permit office is mid-handoff from Pinal County to a brand-new town hall. One call to (866) 471-4088 reaches the emergency plumber San Tan Valley, AZ homeowners reach at 2 AM — 24/7 live dispatch, with the price in writing before any work starts. Whether it’s hidden leak detection with acoustic and thermal gear or a slab leak repair under your living room, every job runs through one live dispatcher.
Start with the two things that define STV plumbing: the water and the ground. EPCOR’s own 2024 report puts hardness at 15–18 grains per gallon — officially very hard, published, no hedging needed — and that mineral load is why water heaters here bake their elements and hidden leaks pit copper from the inside. Under the slab it’s collapsible caliche and expansive clay, the ground that makes a 10-year-old home a slab leak candidate. And around the edges, eight named neighborhoods run EPCOR water with no sewer at all. This page is the map: the newest town, the water, the ground, the legacy — and exactly what to do about each.
Arizona’s Newest Town — And What That Means for Your Pipes
On August 5, 2025, nearly 70% of voters said yes on Prop 495. On September 17, 2025, the Pinal County Board of Supervisors made it official: the Town of San Tan Valley — the largest incorporation by population in Arizona history, immediately the largest municipality in Pinal County, and one of the 15 largest cities in the state, with 123,000+ residents. No competitor plumbing page runs this story. It matters for your pipes because a town this new is still deciding how it works — and that includes who issues your plumbing permit.
From census-designated place to town, in one vote
The numbers tell the growth story: 99,894 residents in the 2020 census, about 103,000 in 2022, then 123,000+ at incorporation in September 2025. The first seven-member council was appointed that same day — Mayor Daren Schnepf and Vice Mayor Tyler Hudgins among them — with Brent Billingsley appointed Town Manager that December. The first municipal office opened at 31505 N. Schnepf Road, and the town joined the Maricopa Association of Governments in May 2026. Say it right: the Town of San Tan Valley — a municipality with its own government, not a neighborhood of Queen Creek, and not a Phoenix suburb. It is a town with its own growing pains, and — relevant here — its own permitting department still being built.
Who issues plumbing permits in San Tan Valley right now?
Pinal County handled permitting, zoning, inspections, police, and streets straight through the incorporation — county services ran through June 30, 2026 while the new Town built its own capacity. Now the Town of San Tan Valley is standing up its own permitting and inspection department, which means the correct answer depends on timing: confirm the current jurisdiction before you pull a permit. That is not red tape for its own sake — gas lines, sewer tie-ins, water-heater replacements, and repipes all need the right inspection from the right office, or you inherit the liability. If you’re adding a gas line for an outdoor kitchen or pool heater this year, ask first: the answer to “who inspects gas work?” is mid-transition, and getting it wrong means redoing the work. When in doubt, call (866) 471-4088 — we check the current desk before any permitted work starts.
Permitted work with the right inspector — guaranteed.
We verify jurisdiction before the permit, not after the fine.
Call — (866) 471-4088Who Provides Your Water? Check Your Water Bill
The single most useful plumbing fact in San Tan Valley: your provider depends on your street — and no map is published that draws the boundary. A local realtor fields “What neighborhoods have Johnson Utilities?” as one of her most-asked questions, and the confusion has only outlived the company that caused it. Here is the honest version, and it’s the only guidance any plumber can responsibly give.
EPCOR San Tan: ~31,000 connections, groundwater only
EPCOR’s San Tan Water and Wastewater districts cover roughly 31,000 service connections per the company’s 2024 Consumer Confidence Report (PWS AZ0411128). The source is groundwater and groundwater alone — the sole supply for the district. Rate-setting here runs through the Arizona Corporation Commission, and 2025 brought the district’s first rate case since EPCOR acquired Johnson Utilities. If your bill says EPCOR, your water is 15–18 gpg hard, your pressure zones are EPCOR’s, and your shutoff procedures are EPCOR’s.
Town of Queen Creek water: ~12,000 customers in north and east STV
The Town of Queen Creek’s municipal water system extends into north and east San Tan Valley — about 12,000 customers in the overlap area, presented to the STV town council in December 2025. Water service only: Queen Creek’s wastewater does not cross into San Tan Valley. Rate-setting on the QC side runs through the town council, and QC also ran new rates in 2025. If your bill says Town of Queen Creek, your water chemistry, pressure, and shutoff map follow QC’s system — not EPCOR’s. Same town, different water.
Why the boundary matters on a service call
Hardness, pressure zones, and shutoff procedures change by system — and a plumber who quotes a softener, diagnoses a pressure problem, or plans a pipe repair without knowing which system feeds your street is guessing at the numbers that size everything. A bill that suddenly spikes is also a different first step by system: the meter test and shutoff hunt are system-specific. When a water bill doubles with no visible leak, hidden leak detection starts with the meter — and the meter test starts with knowing whose meter it is. We ask which provider feeds your street before we size, quote, or diagnose. Every time.
Don’t know which system feeds your street?
Bring the bill — or just describe the symptom. We’ll figure it out.
Call — (866) 471-4088The Johnson Utilities Era — Why STV Trusts No One About Sewers
Ask a longtime San Tan Valley homeowner about sewers and you’ll hear the name Johnson Utilities. This isn’t a rumor — it’s Arizona Republic reporting, state records, and a $100M lawsuit. And it’s the reason every sewer job we run here starts with a camera, never a guess.
What the record actually says
On Christmas Eve 2007, a resident in a San Tan Valley neighborhood called ADEQ to report raw sewage gushing from a manhole cover by his house, flowing down the road between houses and into a nearby wash. He was not the only one: state records document roughly 78 sewer overflows between 2010 and April 2018, and in June 2018 the Arizona Republic reported customers “living in turmoil as taps run dry and sewers overflow” — low water pressure, sewage backing up from manhole covers, noxious fumes from a sewage-treatment plant, and a pump failure that left customers without water, including a charter school where teachers poured water into toilets to flush them. Behind the failures: 530+ recorded complaints, 24% water losses, and one pipe that leaked an estimated 1 million gallons a day for a decade. ADEQ sued for $100 million in May 2019. The old headquarters at 968 E. Hunt Highway is still a Hunt Highway landmark — the name everyone here remembers.
What changed: the EPCOR turnaround
EPCOR assumed operations in 2018 and officially purchased the assets in January 2021, then did something the record shows clearly: it spent. More than $259 million invested since stepping in — including the $80 million Copper Basin Water Reclamation Facility (3 MGD, fully enclosed), which replaced the open-air Section 11 lagoon plant whose odors defined the old era. That is the most-invested turnaround story in our entire Arizona network — real dollars, real facilities, documented in the town council’s own December 2025 presentation.
What the history means for your sewer line today
Today’s system is EPCOR’s — but legacy infrastructure, aging connections, and the post-2018 rebuild all run under the same streets. The honest takeaway: the system is vastly better than the Johnson era, and it still deserves verification before anyone quotes you a dig. Roots at old joints, bellies from legacy settling, and the occasional pre-2018 section that hasn’t been rebuilt — all of it shows up on camera in seconds. A sewer line repair quote without footage is a quote against a system this town learned, the hard way, never to trust blind. We don’t ask for trust on sewers. We show you the inside of the pipe.
Suspicious smell, slow drains, or a soggy yard?
Camera inspection first — you watch the footage live, then we talk options.
Call — (866) 471-408815–18 Grains Per Gallon — In Print, From the Utility
Every city in our network argues about hardness. San Tan Valley doesn’t have to: EPCOR’s own 2024 San Tan water quality report (PWS AZ0411128) publishes the number. Here is the verbatim quote from the FAQ section: “The hardness in your water ranges from 15 to 18 grains per gallon (gpg).” Same report, same section: “We don’t treat drinking water for water hardness that can result in hard water deposits.” That is officially “very hard” water — the first city in our network with a utility-published figure, so no hedging, no “local pros estimate” framing. It’s printed. It’s yours.
What 15–18 gpg does to a home
At this mineral load, the damage is chemistry, not bad luck. Scale bakes onto water-heater elements and settles as sediment that cooks the tank bottom; fixture flow narrows to a trickle as aerators and cartridges crust over; and hard groundwater pits copper from the inside until pinholes open — the signature behind so many of our hidden leak calls. Heaters die years early without the 6-month flush, and softeners aren’t a luxury here — they’re sized to your actual number, which we test free on every visit. A softener quoted without a test result is a guess at the one number the utility was kind enough to publish.
The rest of the report, honestly stated
The 2024 CCR is a full read, and here’s the rest of what it says: sodium runs 85–210 ppm; arsenic up to 5.2 ppb; fluoride up to 1.07 ppm; uranium at 7.3 ppb (2021 data). Lead and copper sampling in 2024 covered 30 homes and met standards — the town’s service lines check out, and EPCOR keeps its lead-service inventory at its safety page. And the report carries a Spanish-language notice (“Este informe contiene información muy importante…”) — official acknowledgment of a Spanish-speaking customer base in a town that’s 25.5% Hispanic/Latino. One more honesty note, straight from the report: there are no San Tan Valley-specific PFAS detections published in the CCR. No PFAS angle here, and we won’t invent one. If you’d like the full aging-out timeline for the equipment this water destroys, see water heater repair — the 15–18 gpg sediment-death timeline is the whole story.
Don’t know your actual hardness?
We test your water free on every service visit — then recommend from your number, not a brochure.
Call — (866) 471-4088The Septic Fringe: Eight Neighborhoods, No Sewer
A first in our Arizona network: named San Tan Valley-area neighborhoods that run on EPCOR water with no municipal sewer at all — septic tanks and pumps on the homeowner. If you bought on the fringe and assumed sewer came with the water, check again. The neighborhoods: Bonanza Highlands, Bonanza Ranch, Chandler Heights Ranches, El Pedregal Estates, Magma Butte Ranches, the San Tan Mountain area, Sun Valley Farms, and Wild Horse Estates I & II.
Septic is a different trade
Septic work doesn’t run through the municipal sewer playbook. Tanks need pump-outs on schedule, pumps fail without warning, drain fields clog, and backflow prevention has to meet current standard — because a failed tank doesn’t just back up your drains, it backs up into your home. Septic work is a different trade, and whoever answers a septic-fringe backup call needs to carry tank, pump, and backflow gear — not just a snake. The warning signs are unmistakable: gurgling drains, sewage smells near the tank or in the yard, slow fixtures across the whole house at once, or the tank alarm sounding. Any one of those means call now, not this weekend.
The nitrate connection, stated straight
Here’s where the fringe meets the water report. EPCOR’s 2024 CCR shows nitrate up to 9.34 ppm against an MCL of 10 — current levels comply but run close to the limit, and the report lists fertilizer runoff and septic-tank leaching among the sources. The history is honest too: in 2017, Copper Basin samples hit 12 and 12.2 mg/L in the Johnson Utilities era, and the local K-8 shut its drinking fountains. For typical city-water customers, the tap meets the standard. On the septic fringe, the nitrate story is a reminder that your tank and your aquifer share the same ground — a maintained system protects both. A yearly water test is cheap insurance; call (866) 471-4088 and we’ll point you to the right test. And when the drains themselves back up — septic or sewer — a camera-tested drain cleaning finds the real blockage before anyone starts digging.
Septic backup, alarm sounding, or just overdue?
Pump-outs, tank inspections, pump replacement — the full septic package.
Call — (866) 471-4088Monsoon Season in a Town That’s Still Being Built
San Tan Valley’s newest storm story is also its most local plumbing lesson: on September 16, 2026, the Majors Brigade equine-therapy farm in the Hayden Acres area went under 3+ feet of water — the owner blamed blocked culverts and nearby construction, calling it worse than last year. Pinal County’s official note told the rest of the story: “the area is now under San Tan Valley’s jurisdiction.” The same storm dropped about 4 inches in 6 hours across the Valley and flooded freeways. That’s the STV monsoon pattern in one scene: a town mid-build, culverts mid-construction, and nowhere for the water to go.
What storms do to drains and sewers here
New construction means construction debris in drainage paths — and in a town adding homes as fast as STV, stormwater systems are a moving target. Overwhelmed culverts push water where it was never designed to go: under slabs, into garages, and — through infiltration — into sewer lines that then back up into the lowest fixtures in the house. If your drains gurgle or your toilets bubble when it rains, that’s stormwater infiltration talking, and it deserves a camera look before the next storm. A drain cleaning with camera inspection finds the actual blockage — debris, roots, a bellied section — and on the sewer side, a sewer line repair starts with footage, never a guess.
And the heat does its own damage
Then there’s the other 110-degree season: 2000s-era STV builds route supply lines through attics, and summer heat bakes PEX and copper from above while 15–18 gpg water works them from inside. Fittings loosen, lines lose flexibility years early, and attic burst pipes turn into ceiling collapses in July and August. If your supply runs through the attic, a summer walkthrough checks insulation, support straps, and connection points — before the heat does the testing for you. Storms flood the outside; heat attacks the inside. We handle both.
Storm coming? Drains acting up when it rains?
Pre-storm walkthrough: roof vents, flue pipes, sewer camera — no guessing.
Call — (866) 471-4088Collapsible Caliche Under Post-Tension Slabs
San Tan Valley has the most specific soil story in our network — documented not by us, but by a foundation company’s STV pages: collapsible caliche soils that fail unpredictably after irrigation or summer storms, plus expansive clay pockets. Monsoon rainfall after long dry seasons causes rapid soil collapse and slab cracking. And the foundation those soils carry is almost always the same: post-tension slab-on-grade, the most common foundation type in STV. That combination — shifting ground under tensioned concrete — is the mechanical engine of the town’s slab leaks.
How the ground breaks pipes
Caliche doesn’t settle politely — it collapses. A dry summer followed by monsoon saturation (or a broken irrigation head running all night) can shift a slab section inches, stressing the copper and drain runs underneath until something gives. Expansive clay does the same job in reverse: swelling when wet, shrinking when dry, working every joint through seasonal cycles. The under-slab lines don’t get a vote. The same local source publishes a $4,000–$14,000 range for STV foundation repair — which is why the cheaper end of the plumbing story is catching the leak early: a leak detection with acoustic and thermal gear pinpoints the break before a single saw touches concrete.
Post-tension slabs change the repair
On a post-tension slab, cutting concrete isn’t just messy — it risks the tensioned cables that hold the slab together. That’s why slab leak repair in STV so often means the overhead reroute: abandon the failed under-slab section, run new PEX through the attic, zero slab cuts. Spot repair and tunneling have their place — the right option depends on the leak’s location, the slab’s layout, and how many more pinholes this water is working on. But on post-tension concrete over collapsible caliche, the reroute is the default for a reason. Ask any contractor here: the ground moves, the slab follows, and the pipes underneath are the weakest link.
Warm spot on the tile? Water sound with everything off?
That’s the slab-leak warning pattern. Get it pinpointed before the ground does more damage.
Call — (866) 471-4088Johnson Ranch Is Aging Out First
Johnson Ranch — about 30,000 residents, homes from the late 90s onward, 18-hole golf course, 31 parks, 3 pools — is the oldest large community in San Tan Valley. Its late-90s and early-2000s phases are now crossing 25 years old, and at 15–18 gpg that age hits harder than the calendar suggests. This is the replacement wave: the oldest equipment in town meeting the hardest water in the network.
What ages out first in a late-90s STV home
Three things, in order: water heaters — 15–18 gpg sediment bakes the tank bottom and eats the anode, so original units from the late 90s are living on borrowed time; supply lines and angle-stop shutoffs — a quarter century of mineral-heavy water and thermal cycling leaves valves that won’t close when you need them most; and softeners that have been fighting this water for decades and are long past their media’s prime. The 2000s–2010s phases behind it — Copper Basin, Pecan Creek, San Tan Heights, Morning Sun Farms — run the same water through younger pipe, so their wave is still building. And at the other end of the timeline, the 2026 new construction at Skyline Village is the builder-grade-defect watch: fast-built phases, fresh warranties, and the under-torqued fittings that weep inside walls for weeks.
Plan the replacement on your schedule
A water heater that dies at 2 AM costs you the emergency premium, the ceiling it floods, and the weekend it ruins. One that gets replaced at year 24 costs you the unit and an afternoon. If your Johnson Ranch heater is original, start planning now — the 15–18 gpg sediment-death timeline is unforgiving, and the 6-month flush plan only buys time if it starts early. Our water heater repair page covers the repair-vs-replace math at this hardness, and when a pinhole opens in aging copper instead, a burst pipe repair isolates the section same-day — before the ceiling does the announcing.

Every service from the emergency plumber San Tan Valley, AZ calls first — one dispatcher, upfront flat-rate pricing, provider-aware on every visit. Pick your problem:
Leak Detection
Bill doubled with no visible leak? At 15–18 gpg, pinhole corrosion pits copper from the inside — in Johnson Ranch originals and 10-year-old slabs alike. Acoustic and thermal pinpointing finds the break before a single tile lifts.
Leak Detection →Slab Leak Repair
Post-tension slabs over collapsible caliche and expansive clay — the ground moves, the pipes underneath don’t get a vote. Spot repair, overhead reroute, or tunnel: we lay out all three with honest numbers for your slab.
Slab Leak Repair →Burst Pipe Repair
Pinholes in mineral-worked copper, attic-routed lines flashing in 110°F summer heat, aging Johnson Ranch supply runs. We isolate the break fast and repair or repipe the section — same day.
Burst Pipe Repair →Water Heater Repair
Officially 15–18 gpg water eats heaters here: sediment bakes, anodes dissolve, showers go lukewarm. We repair what’s worth saving and replace what isn’t — with the 6-month flush plan for this water written on the tank.
Water Heater Repair →Drain Cleaning
Grease, hair, hard-water scale, and the construction debris of a town still being built — plus stormwater overload when the culverts fill. Camera inspection first so we see the actual blockage, then clearing that lasts.
Drain Cleaning →Sewer Line Repair
The Johnson Utilities legacy means we never trust a sewer blind here: camera-located, trenchless options where the line qualifies — you watch the footage live. Plus full service for the septic-fringe neighborhoods.
Sewer Line Repair →Gas Line Repair
Gas is the one trade where “close enough” can kill. Leak detection, pressure testing, new lines for outdoor kitchens and pool heaters — permitted, pressure-tested, inspected by the right office in a town mid-transition.

Typical scenarios based on the housing stock, water, and ground we see across San Tan Valley — illustrative patterns, not real customers.
The 1999 Heater That Ran Out of Borrowed Time
The situation
A Johnson Ranch homeowner hears rumbling from the garage and finds the water heater weeping at the base — the original unit from a late-90s build, now 25+ years old, fed 15–18 gpg water its entire life with no softener and no flush history.
What we found
The tank bottom was caked in sediment inches deep — the signature of this water on an unflushed heater. The anode was gone to nothing, and the T&P valve was crusted shut. The tank hadn’t failed suddenly; it had been failing for years, quietly.
The fix
Same-day replacement with a unit sized for this household and this water — plus a softener loop discussion and the 6-month flush plan written on the tank. On 15–18 gpg, the heater is a subscription, not a purchase: maintain it or replace it early.
The Septic Alarm at 9 PM
The situation
A family on the septic fringe — EPCOR water, no sewer — hears the tank alarm in the evening and notices every drain in the house slowing at once. They’d assumed “sewer” came with the water. It never did.
What we found
The pump had failed and the tank was riding high — effluent backing toward the house. The system was also years overdue for a pump-out, and the backflow prevention wasn’t to current standard. One failing pump, three problems underneath it.
The fix
Emergency pump-out and pump replacement the same night, tank inspection with the lid up so the homeowner sees the condition, and backflow brought to current standard. Then a maintenance schedule — because on septic, the calendar is the plumber.
The New Build That Backed Up in the First Storm
The situation
A 2026-built home at Skyline Village backs up at the lowest fixtures during the first big monsoon — less than a year old, still under builder warranty. The builder blames the storm. The storm is only half the story.
What we found
Camera inspection showed construction debris lodged in the main line — the classic fast-build signature — plus a low section where stormwater infiltrated and pushed everything backward. Not “normal” for a new home: a defect with a paper trail.
The fix
Hydro-jetting cleared the debris, the camera footage documented the bellied section, and the homeowner got a written package — readings, footage, failure analysis — for the warranty fight. Independent proof is what turns “the storm did it” into a covered defect.

San Tan Valley Plumbing FAQs
The questions San Tan Valley homeowners actually ask — answered straight.
Who provides my water in San Tan Valley — EPCOR or the Town of Queen Creek?
Check your water bill — that’s the only honest guidance. Most of San Tan Valley runs on EPCOR’s San Tan Water district (about 31,000 service connections, groundwater only, per EPCOR’s 2024 report), but the Town of Queen Creek’s municipal water extends into north and east San Tan Valley — roughly 12,000 customers in the overlap, water service only. The exact neighborhood-by-neighborhood boundary isn’t published as a map. It matters because hardness, pressure zones, and shutoff procedures change by system. Not sure? Call (866) 471-4088 and we’ll identify your provider on the visit.
How hard is San Tan Valley’s water — do I really need a softener?
EPCOR’s own 2024 San Tan water quality report (PWS AZ0411128) states it plainly: “The hardness in your water ranges from 15 to 18 grains per gallon (gpg).” That’s officially “very hard” — and San Tan Valley is the first city in our network with a utility-published number, so no hedging needed. At 15–18 gpg, scale coats heating elements, narrows fixture flow, and shortens water-heater life — which is why we recommend a softener for most STV homes. We test your actual water free on every service visit, then size the softener to your number.
Who issues plumbing permits in San Tan Valley now — Pinal County or the new Town?
Pinal County handled permitting, zoning, and inspections right through the incorporation — county services ran through June 30, 2026 while the new Town built its own department. Now the Town of San Tan Valley is standing up its own permitting and inspection capacity, so the correct answer depends on timing: confirm the current jurisdiction before you pull a permit. When in doubt, call (866) 471-4088 — we’ll check the current desk before any permitted work starts, including gas lines.
My STV neighborhood is on septic — who services septic pumps and tanks?
We do. Eight STV-area neighborhoods — Bonanza Highlands, Bonanza Ranch, Chandler Heights Ranches, El Pedregal Estates, Magma Butte Ranches, the San Tan Mountain area, Sun Valley Farms, and Wild Horse Estates I & II — run on EPCOR water with no sewer: septic tanks and pumps are on the homeowner. If your drains gurgle, sewage backs up, or the tank alarm sounds, don’t wait — call (866) 471-4088. We service the full septic package: pump-outs, tank inspections, pump replacement, and backflow verification.
What happened with Johnson Utilities — is my sewer system reliable now?
Johnson Utilities served this area for decades — and the record is rough: 530+ recorded complaints, 78 documented sewer overflows, taps running dry and sewage backing up manholes in 2018, a $100M state lawsuit. EPCOR assumed operations in 2018, officially purchased the assets in January 2021, and has invested $259M+ since — including the $80M Copper Basin Water Reclamation Facility that replaced the old open-air lagoon plant. Today’s system is EPCOR’s, rebuilt with that investment — but that history is exactly why the emergency plumber San Tan Valley, AZ calls first starts every sewer job with camera footage, never a guess.
Can a 10-year-old San Tan Valley home get a slab leak?
Yes. Most San Tan Valley homes sit on post-tension slab-on-grade foundations, and the ground underneath is collapsible caliche with expansive clay pockets — soil that shifts after irrigation or monsoon storms and cracks slabs. Add 15–18 gpg groundwater pitting copper supply lines, and a 10-year-old home has all the ingredients. Watch for warm spots on tile, the sound of running water with everything off, or a musty smell near baseboards. Our slab leak repair page walks through the three repair options — spot repair, overhead reroute, and tunnel — and which slab each one fits.
Is San Tan Valley’s water safe given the nitrate history?
Current levels comply — but run close to the limit, and the history is honest: EPCOR’s 2024 report shows nitrate up to 9.34 ppm against an MCL of 10, with fertilizer runoff and septic-tank leaching listed as sources. In the Johnson Utilities era, Copper Basin samples hit 12 and 12.2 mg/L (2017), and the local school shut its drinking fountains. For typical city-water customers, tap water meets the standard. If you’re on the septic fringe, a yearly water test is cheap insurance — call (866) 471-4088 and we’ll point you to the right test.
My home is in Johnson Ranch (built late 90s) — what plumbing is aging out first?
The late-90s phases of Johnson Ranch — our oldest large community, about 30,000 residents — are crossing 25+ years now, and three things age out first: water heaters (15–18 gpg sediment kills them early), supply lines and angle-stop shutoffs, and softeners that have been fighting this water for decades. If your heater is original, start planning the replacement on your schedule, not its.
