"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."

"Repaired broken waterline and brought our water treatment unit up to snuff. Very satisfied"

"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."

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

"Remodeling work cause leakages in the gas lines. I made an appointment with the scheduler BUT Michael Bonsby called me to understand the problem and to explain/assure me that they would ensure a thorough check on the gas line/safety. Mark the specialist spent a good couple hours going through every corner of the gas/water lines and sent me a written report. And he spent time explaining the technical aspects so now I know how to maintain the system. Strongly recommend them for service. Good value to price. Peace of mind!"

"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."

"Very professional service and reasonably priced water system installed in my house. Installed a whole home filtration system to privide continous purified water through the home. Highly recommend!"
