Get matched with top water treatment pros in Bethesda, MD

"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."

"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."

"They replaced my leaking Poly water line from the street to the house with a new copper line. They tried to pull the new line through but were unsuccessful so they eventually had to trench through my yard to install the new copper line. In order to do this, they did have to cut through my concrete driveway which I had to get patched. After some adjustments were made with the new water pressure valve the system works great."

"Very knowledgable and professional. Tech took the time to explain how the system works."

"We got a quote from leaf home water solutions, Frank was our sales person, he was very nice and personable. We decided to buy the system. We have well water. We had hard water. We were sold only what we needed! Nothing else! Our installer was Andy and he was also very nice and cared about the work he was doing! He made sure everything was level and did a wonderful job! Thank you guys! We are very happy and our water tastes good."

"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."
