Katy and west Houston sit on some of the hardest water in Texas commonly 12-18 grains per gallon, often higher. That's why your shower head clogs, your dishwasher leaves spots, your hot water tank fails early and your skin feels dry after a shower. Obsta Plumbing designs and installs whole-house water softeners, carbon filtration and reverse osmosis systems sized specifically for your home and water usage.
We start with a free in-home water test so the system we recommend actually matches your water hardness, iron content and household size. Undersized systems waste salt and fail to soften properly; oversized systems waste money. Right-sized systems quietly do their job for 15-20 years.
We install and service every major brand: Kinetico, Culligan, Aquasana, Pentair, Rainsoft and high-quality private-label systems. Every installation includes a bypass loop so future service is easy, a softener-loop test, and our written workmanship warranty.

Frequently asked questions
How hard is the water in Katy, TX?+
Most of Katy and west Houston sees water hardness in the 12-18 grains per gallon range, with some areas testing higher. Anything above 7 gpg is considered hard, so virtually every home in our service area benefits from softening.
How much does a whole-house water softener cost in Katy?+
Quality whole-house softeners installed in Katy typically run $1,800-$3,500 depending on capacity, brand and whether carbon filtration is included. RO drinking-water systems run $600-$1,400 installed. We provide free in-home assessments and flat-rate quotes.
Do I really need both a softener and a carbon filter?+
Most Katy homes benefit from both. A softener removes calcium and magnesium (the cause of scale); a carbon filter removes chlorine, chloramine and odor. Many of the systems we install are combo softener + carbon units in a single tank.
How long do water softeners last?+
A quality, properly-sized softener should last 15-20 years with annual service. Most failures we see are undersized big-box units that wear out in 5-8 years right-sizing pays for itself.
