"I received a lower price than the other two brands we got bids from and the installation was well done. I did not want to buy a water softener online and install it myself as I knew some plumbing would have to be done so I was willing to pay more to have an experienced person perform the installation."

"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 other plumbers wanted between $425 and $700+ to install our new water softener, even though the plumbing was already in place. Ed's charged $100 and worked for less than an hour to install it and get it up and running. They even disposed of the old one. A great value for a job well done!"
