"Ron and his crew did a great job. He started when he said he would and did a thorough job. Called for the pump truck to remove contamination, added a clean out where there wasn't one, and even brought gravel to fill in the area under house. The helpers were great as well. Thank you."

"Our experience with Dave, Tyler and Levi at Quality Water Systems was simply amazing. It is rare to find a company that is honest, communicates well, walks you through the project and does exactly what they say they are going to do. Water treatment is not easy, it is science mixed with construction. Hiring a great partner for this is critical and QWS is one I'd recommend and hire again and again. Dave's work to engineer our huge Reverse Osmosis system project with a new well and high-flow rate filtration system to take high levels of Boron out of our water was top-notch. Dave and I spent many hours together planning and executing the project. He never got frustrated or flustered, and he answered many questions while also dealing gracefully with the occasional water emergency from another client that needed his immediate attention. The outcome was a solid system that wiped out almost all of the Boron and other particulates and has already processed 194,000 gallons of water into perfect drinking and irrigation water. Levi is super knowledgeable and one of the hardest workers I've ever been around. He is smart, helpful, and calm, even when a challenge would crop up--which will happen on any large project. He was prompt and communicated well throughout the project and was able to help us save time and cost by coming up with really good solutions, while working hard through even the hottest days of the summer. His work was neat and tidy, and along with the rest of the crew I felt completely comfortable having them around knowing they'd look after everything and clean up after each day. He is willing to tackle any task, and takes picture of everything so that we can backtrack & troubleshoot if there is ever a problem in the future. Tyler is funny and engaging and has done a great job to install some of the RO components as well as service our filters and get our remote monitoring system setup. He too worked through hot days to get our system up and running, and was willing to do whatever it took to get the job done. Incredible work ethic from all 3 guys, including a few evenings that stretched to 8p when we were up against needing to wrap up portions of the project to be ready for the next step. I can't say enough good things about our experience and highly recommend QWS if you are looking to create a long-term, robust solution that will last a lifetime and work efficiently."

"We used All Systems Plumbing in 2008 when we remodeled our Kitchen and again this year, when we remodeled our master bathroom. The bathroom was a major remodel with all the plumbing being moved to different locations. The owner, Sean, is a wonderful, professional plumber and a very nice guy. The quality of his work is excellent. He's reliable, calls you back, shows up when he says he will and calls if he's running late. We are in the final phase of the remodel, we will be seeing Sean one more time to install the bathtub, toilet, sinks and all the plumbing fixtures. We will always use Sean for any plumbing problems we have and would recommend him highly to everyone.

"The work was done on-time and within budget.  It has continued to function well.  John has come out at yearly intervals to service it.  This was a relatively complicated job which required extra plumbing, since an existing pressure tank and water softener had to be removed from a small, awkward space.  John seems very knowledgeable and professional.
