"Within a few hours of submitting my search in Angie's List for a company to empty my septic tank, R&E Chief Septic called to schedule the appointment and provide me with the cost. I was surprised at the quick response and immediately set up an appointment. They were on time and quickly went to work. I will definitely use them from now on!"

"The technician was thorough and took the time to address my issues. Being on well and septic, it can be tricky making sure the water is safe, not harmful to the pipes, and is right for things like bathing, Atlantic Blue makes sure all of those things are taken care of."

"Our tech Rich Bush was great. He installed a new water heater along with the thermal expansion tank. All plumbing work was clean and of a pro quality. I highly recommend Mr. Rooter and ask for Rich."

"My pump switch at the tank in my basement was cycling on and off every 40 seconds. The noise of the cycling switch was bothering me at bedtime and something to worry about. First called Tom on the phone and was impressed by his knowledge and experience in the well industry The 2 other companIes I also contacted did not seem to be as experienced and gave me quotes without knowing the problem with my system. I chose Able Well and Pump Service after some research and investigating the area near the well where I found wet soil and runoff below the well head. Able Well and Pump was there in a couple of days. They arrived with a back hoe and quality parts to complete the well repair which turned out to be a corroded galvanized fitting connecting the well casing to the PVC pipe that goes into the house. A stainless steel fitting and a lot of digging solved my problem. Thanks to Tom and Mike for being patient with all my questions and getting the job done. The men also adjusted the pressure in the tank and cleaned the switch contacts. Cost was reasonable for the job. I would call Able Well and Pump again without hesitation. Thanks, Tom and Mike and Angi for the listings of professionals."

"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."
