"Neither technician nor installer could definitely tell me what was really wrong with my old water softener; its behavior (using salt too quickly, even when we were away for weeks at a time) merely suggested that the malfunction was â probably in the electronics.â Nevertheless, I had the softener & control unit replaced because I was tired of dealing with the problem. I have yet to see whether their â solutionâ fixes the issue."

"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."

"The experience beginning with Scott coming out to test the water to Jim installing the water softener tank and reverse osmosis unit was great. They are very professional and informative and the price was just right. I will highly recommend and will refer this company to any family or friends looking to improve their water."

"I ended up having a serious leak & water damage that needed to be repaired before the toilet could be installed. Jerry & Eric explained the problem & arranged the work with a fire & water damage company. Jerry & Eric were great guys...friendly yet professional & knowledgeable. I will definitely be calling this company for future plumbing needs & will recommend them to family & friends."
