How hard is San Antonio’s water?
About 18.4 gpg on average.

Yes — San Antonio has some of the hardest city water in Texas. SAWS water measures 15–20 grains per gallon, averaging around 18.4, which is classified as very hard. Anything above 10.5 gpg counts as very hard, so San Antonio is well past the line.

Yes — hard water is a mineral issue, not a safety issue. The calcium and magnesium in SAWS water are harmless to drink. The damage is to your home: scale buildup in the water heater, pipes, faucets, and appliances.

Those spots are mineral scale — calcium and magnesium left behind when hard water dries. At 18+ gpg, San Antonio water leaves visible residue on dishes, glass shower doors, and faucets within days.

SAWS water carries about 18 gpg of dissolved calcium and magnesium, and those minerals can leave a film on skin and hair after every shower. Many people notice skin feels tight and hair looks flat until the minerals are removed — a softener takes them out at the source. Enter your address above to see your exact hardness.

If your home didn't come with a softener installed, scale starts building in the water heater, pipes, and faucets from day one. Installing early prevents the buildup instead of fighting it later.

Yes. Converse is on the SAWS main system — the same water as San Antonio, averaging about 18.4 grains per gallon per the 2025 SAWS water quality report. That's very hard. We've plumbed 48 homes in and around Converse, including Willow View (Lennar), and the water there needs softening just like the rest of the SAWS area.

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 ~18.4 gpg, expect ~24 lbs/month. Roughly $50-70/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 San Antonio-area homes were built with one — we confirm whether you have a loop before any install.
