"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

The installer guy (Rudy) was also an excellent plumber. You can't go wrong with any of these folks. I highly recommend these folks to anyone who is in the market for a new water softener system."

"Aztec H2O provided a high quality water softener and the install was impressive. Stephen, the owner was very meticulous and took his time to explain the function of the Pentair unit. Best of all, he was a fraction of the cost of other water systems like EcoWater, Culligan, and Life Source! Please call Stephen first!"
