How hard is Seguin’s water?
About 14 gpg on average.

Yes. City of Seguin water runs 10–18 grains per gallon — classified as very hard on average.

Seguin draws from the Carrizo-Wilcox Aquifer and the Guadalupe River rather than the Edwards Aquifer. That makes it somewhat softer than SAWS water on average, but still well into the range where scale, spotting, and appliance wear show up.

The spots are dissolved calcium and magnesium drying onto surfaces. Seguin water averages about 14 gpg — very hard — so you'll see it on glassware, faucets, and shower glass. A softener removes the minerals at the point of entry so the film stops forming.

Mill Creek homes inside Seguin city limits are on Seguin Water; some nearby builds are on GVSUD. The water in both areas tests very hard, so if your home didn't come with a softener, it's untreated.

Yes — very hard starts at 10.5 gpg. At 14, you'll see spotted glassware, scale on faucets, and shortened water-heater life without treatment.

Yes. Marion is served by Green Valley Special Utility District (GVSUD), which sources from the Canyon Regional Water Authority — Guadalupe River plus Carrizo Aquifer — and tests 10–22 grains per gallon (about 16 on average) per its 2024 water quality report. Very hard. We've plumbed 45 homes in Marion's Harvest Hills community (Chesmar), and those homes were built with a softener loop ready for install.

Verified July 2026 against the most recent published utility water quality reports — including the 2025 SAWS water quality report, City of Boerne water quality data, New Braunfels Utilities' hard water facts page, and 2024 reports from CLWSC, GVSUD, Goforth SUD, and the cities of Kyle, San Marcos, and Seguin. Hardness shifts slightly year to year with source blends — we re-check each utility's published report quarterly and confirm on-site before sizing a system.

Most installed water softeners run $1,698-$2,152 for the equipment, with a typical single-unit install landing around $1,800 all-in. Larger homes or systems with an added filter run closer to $2,200. Every quote includes the unit, install, and haul-away — no surprise add-ons. Answer the 4 quick questions above for your exact price.

For a 4-person home at ~14 gpg, expect ~18 lbs/month. Roughly $40-55/year in salt.

Plan to check the salt level about once a month and top it up every 4-6 weeks — roughly one 40-lb bag, depending on your hardness and household size. Beyond salt, a standard softener essentially runs itself: no filters to change, and it regenerates automatically on its own schedule. We size it so it’s efficient from day one.

Salt-based softeners typically last 10-15 years. Premium systems (better resin, dual-tank designs) reach 15-20. The resin bed is the wear part — it can be replaced once for roughly $300-500 to add another decade of life.

Properly sized systems lose 2-5 PSI max — imperceptible. Undersized systems can lose 10+ PSI. NSF/ANSI 44 caps the standard at 15 PSI at peak flow. We size based on your home’s actual demand, not square footage.

Yes for healthy adults. Softening adds about 7.5 mg of sodium per grain of hardness removed — at SA-area hardness that’s ~30-40 mg per 8 oz glass, less than a slice of bread.

Most installs run 2-3 hours, single trip. Water is shut off for the middle ~30 minutes. You need one adult home to walk through the completion check — our crew handles everything else.

Tankless heaters are especially vulnerable to hard water. Manufacturer manuals commonly require softening or regular descaling to keep the warranty valid in hard-water areas, and SA-area water is well into that range. A softener helps protect your warranty and can extend a tankless heater’s life in hard water.

Salt-free systems condition water — they prevent scale from sticking but don’t actually remove calcium and magnesium. They can work in mild-hardness areas, but at SA-Austin levels (15-24 gpg) they fall short. We only recommend true salt-based softeners here because that’s what actually works in our water.

A pre-installed plumbing stub that lets a softener tie in without cutting pipes. Many newer Seguin-area homes were built with one — we confirm whether you have a loop before any install.
