Water Heater & Softener Repair in Schertz, TX
Armor Pro Services handles water heater and softener repair across Schertz, TX, where SAWS water runs about 20 grains per gallon and scales heaters and wears out softeners faster than the brochure says. We diagnose the actual fault before quoting, size softeners from an on-site water test, and pull the City of Schertz permit when a changeout needs one. Licensed under Texas RMP #36282, and you pay the price we quote.
The four calls that stack up in this town: tankless heaters that need descaling, tank heaters at end of life, softeners sized wrong the first time, and expansion tanks or PRVs failing on the 8-to-12-year-old builds toward Cibolo. We cover all four below with the real specs, not brochure numbers.
What we do in Schertz
Softener sizing for Schertz hardness levels
Local hardness commonly tests 18–22 gpg. We size by capacity (grains between regenerations) instead of tank diameter, and pair with a sediment pre-filter to protect the resin from the iron content. See how our [water softener installation in Schertz](/water-softener-installation-schertz-tx) is scoped from the on-site water test.
Tankless water heater repair and descaling
Rinnai, Navien, Rheem: we diagnose the error code and amp-test before quoting a part. Most Schertz tankless repairs are really a scaled heat exchanger, so we run a proper citric-acid flush (not vinegar), clean the inlet screen, and verify combustion. If the unit's still under manufacturer warranty, we file the claim paperwork so you don't have to argue with a call center. Call 210-212-7667 and we'll tell you straight whether it's a part or a flush.
Builder PEX repairs
Sub-slab manifold systems with copper crimp rings have a known failure mode in the Cibolo / Schertz area. We repair the leak, then assess whether a manifold relocation makes sense for the rest of the home.
Conventional tank water heater repair and replacement
We repair before we replace when a repair is honest. A pilot that won't stay lit is usually a thermocouple; no hot water on an electric unit is usually an element or thermostat. When the tank itself is leaking or corroding through, a standard 40 or 50-gal swap runs about a half-day with new T&P, expansion tank, pan, and code shut-off, permit filed with the City of Schertz when required. Don't replace a heater under 8 years old over a $30 part, get it diagnosed first.
Whole-home water filtration + softener combo
Carbon block ahead of the resin tank, sediment filter ahead of the carbon. The carbon strips chlorine that would otherwise oxidize the resin; the sediment filter catches the iron and grit that would foul it. Same footprint as a standard install — twice the resin life.
Yard and irrigation leak repair
Schertz lots have a lot of irrigation, and the polyethylene mainlines from the meter to the backflow are the usual failure point at year 12–15. We pinpoint with acoustic gear, dig only the bad section, and re-bed in clean fill so the next failure isn't six feet away.
Backflow assembly testing & repair
Annual RPZ and DCV testing for irrigation and fire lines, filed direct with the City of Schertz. Common issue out here: assemblies that froze during a hard winter and quietly cracked the bonnet. We rebuild in place when parts are available.

Technical notes
Tankless water heater repair and descaling in Schertz
Most tankless repair calls in Schertz trace back to one thing: scale in the heat exchanger. At roughly 20 gpg, an unsoftened tankless unit fouls its exchanger inside two seasons, then starts short-cycling and eventually throws an ignition or flow error. Before we quote a part, we descale with a proper citric-acid flush (not vinegar), pull and clean the inlet screen, and verify combustion. About half the units we're called out to fix don't need a part at all, they need the flush the last company skipped.
When a part genuinely is failing, common culprits on Rinnai, Navien, and Rheem units are the flow sensor, the flame rod, and the fan motor. If the unit is still inside its manufacturer warranty window, we file the claim paperwork so you're not arguing with a call center about labor. And if we're already onsite for a repair, we'll tell you straight whether softening the incoming water is the fix that keeps this from happening again.
Conventional tank water heater repair and replacement in Schertz
A tank water heater repair in Schertz starts with a real diagnosis, not a sales pitch. A pilot that won't stay lit is usually a thermocouple or gas control valve, not a whole new heater. No hot water on an electric unit is usually a failed element or thermostat. We test the actual fault first. Where it makes sense, a repair on a heater under about 8 years old is the right call. Our dedicated page on [water heater repair in Schertz, TX](/water-heater-repair-schertz-tx) walks through the no-hot-water diagnostics before you spend on a changeout.
Replacement is the right call when the tank itself is leaking from the seam or the anode is long gone and the tank bottom is corroding through. In Schertz's hard water, that clock runs faster: sediment bakes onto the element or insulates a gas burner, and a heater that should see 12 years often taps out at 7 or 8 without a softener upstream. A standard 40 or 50-gallon swap is a half-day job and includes a new expansion tank, T&P valve, drip pan, code-compliant shut-off, and the City of Schertz permit. We haul the old unit away the same day. Anode-rod replacement around year 3 is the cheapest way to stretch a tank's life, and we'll flag it on any service visit.
Water softener sizing in Schertz for 20 gpg hardness
A water softener in Schertz has to be sized for the water it's actually treating, and Schertz water is genuinely hard. Local testing commonly lands at 18 to 22 grains per gallon. We size by grain capacity (how many grains the unit clears between regenerations) instead of tank diameter, because that's the number that determines whether the softener keeps up with your household. For a four-person home at 20 gpg, the math points to a 48,000-grain unit minimum, demand-regenerated, with a 64,000-grain giving headroom for guests and irrigation top-up.
Two things quietly kill softener resin in this part of Guadalupe County: iron fouls the beads and free chlorine oxidizes them. A 10-year resin can be done in five if neither is filtered upstream, which is why our standard install adds a 5-micron sediment filter and a carbon block ahead of the softener. If you're pricing a new install rather than a repair, our [water softener installation in Schertz](/water-softener-installation-schertz-tx) page walks through how we scope it from the on-site water test.
Expansion tank and PRV replacement in Schertz new builds
Expansion tank and PRV repair is one of the most common calls we get on Schertz's newer subdivisions, and it's tied to age. Homes built roughly 2008 to 2015 in the Cibolo Valley Ranch and Crossvine areas are now in the 8-to-12-year failure window for the thermal expansion tank and the pressure-reducing valve at the main. A waterlogged expansion tank shows up as the T&P valve on the heater weeping every time the burner fires, or a hammering knock when a fixture shuts. That's not a heater fault, it's a dead expansion tank, and swapping the tank is a fraction of the cost of chasing the wrong repair.
A failing PRV shows up as incoming pressure that climbs above 80 psi or swings all over the range. High static pressure is what shortens the life of every fixture, supply line, and the water heater downstream of it. We test static pressure at a hose bib, confirm the PRV is the fault, and replace it with a properly set unit dialed to the 60 to 70 psi range. Since 'expansion tanks repair schertz' is already the query most likely to land you here, it's worth saying plainly: on an 8-year-old build with a weeping T&P, the expansion tank is the first thing to check, not the last.
Why softeners fail early in Schertz
Two things kill softener resin in this part of Guadalupe County: iron and chlorine. Iron fouls the resin beads, and free chlorine in municipal water oxidizes them over time. A 10-year-rated resin can be done in five if neither is filtered upstream.
Our standard install adds a 5-micron sediment filter and a carbon block ahead of the softener. It adds a small footprint at the manifold but doubles practical resin life.
What 20 gpg actually does to your house in 24 months
Unsoftened Schertz water at 20 grains per gallon deposits roughly 7–9 pounds of mineral inside a typical home's plumbing every year. Most of that ends up in the water heater tank (where it bakes onto the heating element or insulates the bottom of a gas burner) and in the heat exchanger of any tankless unit.
On the fixture side: aerators clog every 4 months, glass shower doors fog with calcium etching that won't come off, and dishwashers leave a white film on glassware no matter what detergent you switch to. None of it is dangerous. All of it is expensive in aggregate.
A correctly sized softener — 48,000 to 64,000 grain capacity for a four-person household — handles all of it for the cost of a bag of salt every six weeks.
Builder PEX in Cibolo subdivisions: the failure pattern
Homes built between roughly 2008 and 2015 in the Cibolo Valley Ranch and Crossvine areas frequently used PEX with copper crimp rings on a sub-slab manifold. The copper crimp rings — when over-crimped or installed on a slight angle — develop pinhole leaks that show up as warm spots on tile or unexplained bumps in the water bill.
We pinpoint, expose the failed crimp, and either re-make it with a stainless cinch clamp or re-route the run overhead in PEX-A with expansion fittings. If you've had three or more failures, an attic re-route of the whole manifold becomes the cheaper long-term play.

Frequently asked
How big a softener does a 4-bedroom Schertz home need?
At 20 gpg and four occupants, the math points to a 48,000-grain unit minimum, demand-regenerated. A 64,000-grain gives more headroom for guests and irrigation top-up.
Can you fix a leaking PEX manifold under the slab?
Yes. We pinpoint the leak with acoustic equipment, expose only the failed run, and either spot-repair or re-route the line overhead in PEX-A.
Do you do water heater repair in Schertz, or only replacement?
Both, and we diagnose before we quote. Many Schertz water heater calls are a thermocouple, gas control valve, element, or thermostat, not a whole new heater. We test the actual fault first and only recommend replacement when the tank is leaking, corroding through, or past about 12 years. On tankless units it's usually a scaled heat exchanger that needs a citric-acid flush rather than a part.
My T&P valve keeps dripping and the heater is only 9 years old. What is that?
On an 8-to-12-year-old Schertz build, a T&P valve weeping every time the burner fires is almost always a waterlogged thermal expansion tank, not a bad heater. We test the tank and the static pressure at a hose bib. If pressure is climbing above 80 psi, the PRV at the main is also due. Both are common in the Cibolo Valley Ranch and Crossvine subdivisions at that age, and swapping the expansion tank is a fraction of a heater replacement.
Do you handle commercial plumbing in Schertz?
Yes, light commercial: backflow testing, grease line jetting, and tank/tankless water heater work for offices and small retail.
Will a softener help my tankless heater?
Massively. Unsoftened Schertz water will scale a tankless heat exchanger inside two seasons — the unit starts short-cycling and eventually throws an error code. Softening upstream extends practical heat-exchanger life from 6–8 years to 15+.
How much salt does a Schertz softener actually use?
A demand-regenerated 48k-grain unit on 20 gpg water for a four-person household burns roughly one 40-lb bag of salt every 5–6 weeks. Time-clock units waste 30–50% more salt — we don't install them.
Do you service the Schertz Master Planned Communities (HOA)?
Yes. We provide license, insurance, and scope documents to the HOA management company before work starts and observe weekday work-hour windows when required.
