"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 $$$."

"Great crew and awesome service. I had a hard time finding a place interested in dismantling a rusty failed 10k steel water holding tank. These guys got it done quickly, cleanly and they were very nice and good about communication. Top notch!"

"I have not written a review for a person I have hired in Angie's list and this is the first one... With countless options for water filter and softener in the market, it can be very overwhelming. Products, technology and quality of customer services are at stake. Most products and technology at this point in time are top notch. The prices as well become so competitive... Bottom line, when having an investment such as water softener and filtration, it boils down to education and customer service. This is clearly where Ed and his crew have a significant edge...his attention to detail, thoughtful consideration and assurance of quality of work is unparalled. You can text and call him and you can almost guaranteed he will reply. This is PEACE OF MIND that no other pricing nor product nor a company can deliver! He admits that his pricing is certainly not the lowest one nor its the highest but guarantees its VERY competitive! And based on my countless of research, it is indeed one of the best one out there! His product is neither the most cutting edge (a TESLA dor example), but its like buying a TOYOTA, a reliable and no nonsense working machine that takes in all replacement parts and DOES the job! What you want in your house is a workhorse backed up by solid customer service that will last you a long time. I have not yet seen this but so far his efforts and reviews has proven this greatly!!! Ed is your water guy! He knows his stuff and has the passion to make it known and delivered with his outstanding care to his customer!"
