What's Really in Houston Tap Water?

Houston's water meets every federal legal standard. But legal limits and health guidelines are not the same thing, and the Environmental Working Group found contaminants above science-based health guidelines in the City of Houston system.

Why We Can Quote You Over the Phone

Most companies insist on coming out first. Here's why we don't have to.

1
Your water is already on public record
Every water district in Texas has to publish what's in its water once a year, and we read your district's report before we call you.
2
Our installs are standardized
Same Clack WS1 valve, same 1" or 1.25" connections on the main line, same licensed plumber.
3
We only come out when we actually have to
If your main line is somewhere unusual, we'll say so on the call and set up a look before anything is final. Otherwise the number we give you is the number you pay.

Jacob is a great representative to work with very informative I highly recommend him. After talking to him it was installed in a couple of days. The equipment is top of the line. Installers knows what they are doing and didn't take long to get it installed.
