Schertz, TX Plumbing — Hard Water, New Builds, Real Fixes
Schertz water hits hard — like, leaves-a-ring-on-the-glass hard. Green Valley and Schertz-Cibolo are heavy on calcium, and an unsoftened tankless heater will scale up its heat exchanger inside two seasons. Most of what we do out here is softener sizing done right the first time, descaling the units the last guy never serviced, and patching builder-grade PEX that's giving up early.
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.
Tankless descaling and warranty service
Rinnai, Navien, Rheem — we run a proper citric-acid flush (not vinegar), pull and clean the inlet screen, and verify combustion before we leave. If your unit's still under manufacturer warranty, we file the claim paperwork so you don't have to argue with a call center.
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.
Water heater replacement
Standard 40 and 50-gal tank swaps with new T&P, expansion tank, and pan are usually a half-day. Permit filed with the City of Schertz when required.
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
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.
What plumbing costs in Schertz

- Combo softener + carbon filtration: $2,950–$4,650 — Adds whole-house chlorine removal upstream of the resin — doubles practical resin life.
- Tankless descaling service: $285–$485 — Citric-acid flush, inlet screen clean, combustion verification, warranty paperwork if applicable.
- Tank water heater swap, 50 gal: $1,750–$2,350 — Includes expansion tank, T&P, pan, code-compliant shut-off, permit, and haul-away.
- Sub-slab PEX leak repair (single failure): $685–$1,485 — Acoustic locate, expose crimp, re-make in stainless cinch or re-route overhead in PEX-A.
- Yard/irrigation mainline repair: $385–$985 — Single failure point — locate, dig, repair, re-bed. Larger trenches priced per linear foot.

We test hardness, iron, chlorine, and TDS in your kitchen — not by guessing from your zip code.
2 — Sized to your household
Capacity (grains between regenerations) calculated from your actual occupants and water test, not from truck stock.
3 — Permitted install where required
City of Schertz permits filed for water heater swaps and gas work. Inspection scheduled, attended.
4 — Water re-tested at the kitchen tap
Before we leave, we verify hardness is below 1 gpg at the fixture. You see the test.
5 — Salt-fill walkthrough + 1-year service
We show you how often to refill, what salt to use, and offer a free year-one service check.
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 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.
