"Chris is very knowledgeable about water treatment. He did a nice job on the install, was on time and helped me get the system that was right for me. He was very helpful and answered all me questions. He did not try to up sell me on something I didn't need. The price was also significantly better than other bids that I got. We had very hard water and was ruining everything. It is nice to have normal water again. If you are in the need for water treatment I would definitely get in touch with this company"

"Abdiel was super to work with. He really knew his stuff and explained so many things to me that I did not know before. He gave me such a great deal that i couldn't say no. The system is perfect and the water delightful. Lucian installed the system. Couldn't have asked for anyone more gentlemanly. Very meticulous about his work. Seems to be a great company all around."

"first jim needem was so professional, caring about my water situation. he immediately called me back and set up a service for a sunday. Ben came and i can not say enough about his patience,professionalism, caring and was so helpful with my situation. He took the time to educate us and help us understand the system. He checked all points of our water in our house. he also had some suggestions for the future which we will do. this company also has a person to extract water thru my insurance for my carpet. He left nothing out. His expertise and honesty was amazing. I hope everyone who reads this will use this company. If there were 20 stars they would definitely get them. I am so thankful for their customer service, and kindness. Thank you Jim and Ben colleen L in Broomfield colorado"

"Patrick was the answer to my prayers! My water heater went out and I needed someone who could convert the old tank to a tankless system. My kids and I were without water for over a week because the first company I contacted was a no-call/no-show. But Patrick was able to stop by and provide an estimate the next day. Not only was Pure Water Services able to complete the work quickly but it did not cost an arm and a leg. I can not say enough good things about how Patrick helped out out when we really needed the help. I highly recommend him to anyone looking to do a water heater conversion!"

"We had blockage in one of our main drain pipes, causing water to back up in the kitchen sink, bathroom sink, and washing machine drain. Jason was able to get to our house within an hour and had it fixed in less than an hour. Overall a very easy process and easy to work with."

"I would highly recommend Brady (BC Plumbing) to anyone. I was thoroughly impressed with his prompt and excellent service on the install of my water main. His prices are more than reasonable. I admired his patience and ability to work with me as I accepted his offer in June, but did not get back to him until late September. At which point there was no delay in getting things done! Thanks Brady and your marvelous crew!"
