Customers say: Quick response

"They were knowledgeable, experienced, and efficient. Duke Energy turned off my gas when a leak was detected after line replacement in my neighborhood. After strategizing how to tackle the project, D&P fixed the leaks in a little over two hours. I had contacted another plumber whose estimate included a crew for a whole day and a rip and replace of 70 ft of gas pipe to the tune of $8200! D&P actually repairing the problem was much more cost effective."

"Our tankless water heaters stopped working. Chris quickly found the problem being the snow/ice blocked intake and venting outlets. He cleared the blockage and made suggestions for future improvement. Throughout the process, Chris was courteous and professional. We would recommend his service."

"Whoever Nick sends to work at our house has always figured out what needed doing (and not more) and been able to get it done quickly, surely and cleanly. In this case we had just at our water main changed which cause sediment to clog fixtures and kill water pressure. Chris gave us the good news that a replacement fixture and part was all that stood between us and square one----and he fit us in the next day so that we could go out and buy the kitchen faucet we needed."

"I purchased a water softener package from Ohio Valley Pure Water.  Unfortunately, my home setup is not easily adaptable for a water softener.  My clean out is on the back-side of the house but my main is on the front.  The difficulty in setup was enough for Ohio Vally Pure Water to recommend Rodney for the job.
Rodney is awesome.  He did the work the well, didn't complain once about the setup and so far everything is working well.
