Desert Water Services, LLC

Mark rebuilt my home water treatment system five years ago which saved me many $$$. Mark works conscientiously with attention to detail. I was shocked to see he polished my water softener on the outside to make it look new. I also had him install a reverse osmosis system under my kitchen sink which he did neatly, this allows me to utilize the space underneath effectively. I can recommend Mark's work confidently.

On recommendation of a well specialist I purchased a spin filter that ‘cleans itself’ for our well water. It didn’t. Within a few months it was clogged beyond what frequent manual cleaning would improve. Consulted with several plumbers who in turn consulted with water specialists - the solutions were wide ranging and all cost prohibitive. Van Marke plumbing supply has provided great customer service so I called to gain insight into what I really needed that wouldn’t break the bank. “If we have water quality questions we call Desert Water Services. Nice guy, knowledgeable, good prices”. So I called DWS, owner Mark McCoy arranged to meet me that afternoon (👍🏻). That visit was a cursory assessment for him but I learned exactly the information I’d been seeking for a year. Once he had reviewed

It was a pleasure working with Mark to install our RO and water treatment system at our house. I received quotes from four different vendors, and the prices varied greatly. One vendor didn’t even bother to visit the site to discuss it with me. We chose Desert Water Service because it offered the best value. During Mark’s visit, we discussed what we needed in a system. He provided several options and explained the maintenance and future costs associated with each. He clearly aimed to engineer a solution that met our needs, rather than just selling a pre-made kit like the others seemed to do. He arrived on time, did professional work, left the work site spotless, and followed up in the following days to ensure everything was functioning as expected. I highly recommend Desert Water Services

Mark is a wealth of water knowledge! He just designed and installed a water system with softening, RO ice and RO drinking water for us. It is fantastic to not have to buy and lug home heavy flats of spring water anymore. It’s some of the best tasting water I’ve ever had. I cannot recommend Mark and Desert Water Services highly enough. Thank you Mark!

I've known Mark for years. He's done plenty of work at my home and he recently installed a new whole house water softener. The installation was quick, neat and economical. His attention to detail is great (that's why I use no one else) and we've never had softer water. He knows what he's doing and he takes care of his customers. Thanks Mark!
