"Update - Issue has been resolved. The bitter taste was from the mineral filter (Very strong). I was looking for Costco bottle quality water with some minerals, but the mineral filter adds a VERY significant amount. The Salesperson stopped and removed the filter, and tested my water. McCowin water made it right, and offered to credit me for the mineral filter. I have had my reverse osmosis system in place for about a month now and all good. ———— Installation was good, but my review has to do more with Scot the salesperson. I received a text from him following up on the install and responded with several concerns. 1st) Water from the reverse osmosis was not crisp, and I told him it had a metallic taste to it and did not taste like Costco water, which he assured me that it would and was the major selling point for me to purchase this system. When I contacted Scot later that evening to discuss my concerns, he told me that the water would not taste like Costco brand because I chose to add minerals back into the reverse osmosis water and that if I wanted to spend more money to get the water to a Costco taste level I could. He also told me while making the sales pitch that he would come back and do a test of the water to make sure it was to my liking. When I asked about the test, he said that he was not available and had no idea when he would be back in my area. Then he abruptly ended our conversation without really addressing my concerns by saying bye, have a good evening. For peace of mind, I purchased my own water test kit/strips. I found that the water appears to be safe but it still tastes as if the metal is in the water. Be aware and be skeptical, do not just take the salesperson's word for it. If you do decide to purchase, do an independent before and after test to make sure you are getting what you paid for and requested. Once they install the system, they are on to the next."

"Hats off to Daniel W. from Western Rooter who installed a water filtering system in my garage. Right from speaking with him on the phone, he was courteous, friendly, and very knowledgeable in his craft. You would think that companies would offer you their premium package right from the beginning but not Daniel. Instead, he asked what I was looking for and took the time and effort to send me multiple filtering systems (including Amazon choices) to choose from. This gesture tells you that he is looking for the customer's best interest at hand which is outstanding. Once I selected my choice, he thoroughly explained the contract and servicing process as well as answered all the questions I had. No big complicated words or complex contracts to decipher but simple and easy was the way Daniel pitched it. All in all, Western Rooter needs to hire more professional, knowledgeable, and charismatic people like him as he is a prime example of excellent customer service. I plan to use his services in the future and will definitely refer him to neighbors, friends, and family. Thank again Daniel W."

"We had a hot spot on the floor and a high gas bill last month leading us to suspect a slab leak. We called several plumbing services and Personal Plumbing was able to come out the next day with their own slab leak tech. The techs were on time and took about three hours to find the leak and reroute and place pipe to repair. They were able to avoid more holes in the drywall by placing the pipe on the exterior garage side, extending us savings. They also showed great integrity by letting us know that any repair would also have to replace factory pressure valve that was no longer working (putting pressure on our system). We will definitely keep them in mind for any other plumbing work we need done!"

"Unbelievable customer service. I’ve needed a new water heater for a while, been calling around for quotes. And this was the best!! They came out within a day and took out the old water heater and installed the new one within a few hours.

"Repaired my leaking filtration system, gave it a tune-up, corrected the back-flush setting which was wasting water/money, and said I'd get another 7 years out of it. Very happy I didn't have to replace it."
