"Routine Water system inspection after installation. Very friendly and thorough"

"Enjoying our new water treatment system. Our old one was leaking. Now we have a new stainless steel system in our basement. Our salesman, Scott, was very friendly and helpful. I would recommend this company to anyone who us interested in a water treatment system."

"Excellent plumbers and water treatment systems experts! Josh is fabulous.... so professional, courteous, AND knowledgeable.... Alwasy a pristine job, solves many issues realiably and I can count on him to know just what to do and how to do it!"

"Previously, I had another system. The Hague uses a fraction of the salt that my previous system used - which mean less bags and less waste! The RO is even better! I never have to haul in 5 gallon bottles. Saves my back and the planet. All we use are reusable bottles now! My Hague RO water tastes so good - it is hard to drink other water."

"Fantastic service. This is the second time we've hired R & G Water Systems. Both times we had an issue in the middle of the night and they were able to send someone out first thing in the morning. They replaced our well pump the same day (within a few hours of calling actually). This went as smoothly as the first time we hired them and would definitely continue to use them."

"Services were prompt, clean and efficient. Tech was knowledgeable and personable. Water heater was affordable. Estimate (free) was done on site - not guessing over the phone."

"The technician was very professional, courteous and knew exactly what needed to be done to replace the backyard water bibb/spigot. He did the replacement successfully and tested for any possible leaks afterwards."
