San Antonio Water Softeners
Walk into the garage of a house built in the last twenty years in Alamo Ranch, Stone Oak or Schertz and you will likely find two capped pipes sticking out of the wall near the water heater. That is a softener loop, and builders here install it as a matter of course because they know what the water is. San Antonio draws most of its supply from the Edwards Aquifer, a limestone formation, and the water arrives at your house carrying dissolved calcium and magnesium that come back out as scale on everything they touch.
A softener trades those minerals for sodium as the water passes through a resin bed, then rinses the resin with brine on a schedule. The result is water that does not leave crust on the shower glass, does not bury a water heater in sediment, and rinses soap off the way water in a soft-water city does. In the older neighborhoods inside Loop 410 and near downtown, there is no loop, so we cut one in where the main enters the house and run a drain for the regeneration cycle.
Sizing is the part that gets skipped. A softener is rated by how much hardness it can remove between regenerations, and that depends on your water test and how many people are in the house. The mechanics of resin, salt and regeneration are laid out on our water softeners page. Here is how it works out in San Antonio homes.
Is It Time
Most homes here need one. These are the signs it has become expensive to keep going without.
The haze is mineral scale. Vinegar takes it off; a softener keeps it from coming back.
Scale on the tank bottom. Softened water slows the buildup to a crawl and adds years to the heater.
Minerals drying on the surface. Rinse aid hides it; soft water removes the cause.
Soap reacting with hardness and leaving a residue. One of the first things people notice after a softener goes in.
Aerators and spray heads scaled shut. A recurring small repair that a softener retires.
The builder made it easy. Connecting a softener to an existing loop is a short install.
Softener Services
New installs, replacements, repairs and the drinking-water systems that pair with them.
Install Day
Test, size, install, set. Then salt every month or two and forget about it.
We test at your tap, count bathrooms and people, and find the loop or the spot where one will go.
Unit, loop work if needed, drain and bypass, itemized and honored for 72 hours. Financing through Service Finance Company if you want it.
Plumbed, drained, powered and programmed for your hardness and household. Outdoor spigots left hard if you ask.
We test the softened water, show you the bypass and the salt, and answer the question everyone asks about the taste.
Save on the work your home needs most.
One test, one written quote, one afternoon in the garage.

It comes down to two numbers: how hard your water is and how much of it your household uses. Softeners are rated in grains of capacity, meaning how much hardness they can remove before they need to regenerate. Multiply your hardness by daily water use and you know how fast a given unit will exhaust. San Antonio water is hard enough that a family of four in a three-bath house usually needs more capacity than the smallest units on the shelf, but oversizing wastes money and lets the resin sit too long between cycles. We test your water at the tap, ask about the household, and size from there. A unit that regenerates every few days on a sensible schedule is the goal.
It is the builder doing you a favor. A softener loop is a section of the main water line, usually two capped pipe stubs on the garage wall near the water heater, that routes all the water for the house through one spot so a softener can be connected without cutting into the plumbing. There is normally a hose bib or drain nearby for the regeneration cycle and an outlet for the control valve. Homes built across the far west side, Stone Oak and the I-35 suburbs in the last couple of decades almost all have one. Connecting a softener to an existing loop is a short, clean install, and it is the cheapest a softener will ever be to add to that house.
Not salty, but different. A softener exchanges hardness minerals for a small amount of sodium, in proportion to how hard the water was to begin with. In San Antonio the water is hard, so the sodium added is more than it would be in a soft-water city, but it is still far below what most people would describe as salty; the change people notice is more that the water feels slick and lacks the mineral taste they were used to. If anyone in the house is on a sodium-restricted diet, or you simply prefer the taste, a reverse osmosis tap at the kitchen sink removes the sodium along with everything else for drinking and cooking. Many of our softener installs include one.
Yes, and we usually recommend it. There is no benefit to softening water that goes onto the lawn, and softened water on plants and soil is not ideal over time. Skipping the irrigation also means the softener regenerates less often and uses less salt. In a house with a builder loop, the outdoor lines often already branch off before the loop. In an older home where we cut the loop in, we can leave the hose bibs and the irrigation feed upstream of the softener. Tell us which outdoor taps you want hard and which you want soft, such as a spigot for washing a car, and we will plumb it that way.
Salt depends on your hardness and water use, but for a typical San Antonio household expect to add a bag or two every month or so; keep the brine tank about half full and never let it run empty. Service is lighter than most people think. Once a year, check that the brine tank has not formed a salt bridge, a hard crust that leaves the water below it untouched, and clean the brine well. Resin beds last many years on city water, less on wells with iron. If you notice scale returning, the unit running through brine too fast, or the control head cycling at odd hours, call us. Care Club members get the softener looked at during the annual plumbing inspection.
