Will use for any future plumbing needs. Had a 70 ft buried gas line installed for a generator along with Riser and regulator. They showed up on time for both the estimate and the work. Finish the work in a timely manner communicated every step of the way there were no surprises. 100% recommend.
Water Softeners and Whole-Home Filtration
Houston-area water is hard. It carries enough dissolved mineral to leave white scale on your fixtures, shorten the life of a water heater, and stop soap lathering properly. A softener is the usual answer to that, and it is the one most homes here end up needing.
A water filter is a different thing solving a different problem. Where a softener targets hardness, a whole-home water filter targets what the water tastes and smells like: chlorine, sediment, and the other things that make people buy bottled water for a house that already has a supply. Plenty of homes want both, and they are usually installed together at the point the main enters the house.
We install, replace and service both. GarSan obtains required permits and coordinates inspections when required for the scope and jurisdiction.

What customers say
Responsive, easy to work with. Clearly explained the issues and the options. We are a small business and will definitely keep Jose on speed dial.
Jose from GarSan Plumbing Services came out to assess and locate a water leak that had caused significant damage inside my home. He was punctual, or early, for each visit and spent the time required to assess the situation and provide cost effective solutions. I think he did a fantastic job and I would definitely call him again when I need plumbing work in the future. Thank you!

Questions
Water Softeners & Filtration FAQ
Not answered here? Call and ask. We would rather talk it through.
What is the difference between a water softener and a water filter?
A softener removes the dissolved calcium and magnesium that cause hardness, which is what scales up your fixtures and your water heater. A filter removes things you can taste and smell, like chlorine and sediment. They are not interchangeable. If your problem is white crust on the taps, that is hardness. If it is the taste, that is filtration.
Do I need both?
A lot of homes in this area do, because Houston-area water is genuinely hard and also chlorinated. But we will tell you if you only need one. There is no point selling you a filter for a hardness problem.
Where does a whole-home water filter go?
At the point the main water line enters the house, so everything downstream of it is filtered. If a softener is going in too, the two are normally installed together in the same run.
How much maintenance is there?
A softener needs salt topping up on a regular basis. A filter needs its cartridge or media changed on a schedule that depends on the unit and your water. We will tell you what yours needs before you buy it.
Do you install salt-free systems?
Yes. They work differently to a conventional softener and they suit some households better, particularly where somebody would rather not add sodium to the supply. We will explain the trade-off rather than just selling you the more expensive one.
