Reverse Osmosis

I highly recommend David and his team! They were kind, quick and knowledgeable. We can finally stop looking for a great water treatment provider!

You won’t find anyone more knowledgeable about water and passionate about providing great service to his customers than Mark Dierolf and his top-notch team. John and Ernie did a terrific job installing my system and took great care to educate me along the way. I highly recommend Dierolf to anyone in need of consultation and installation of a water system.

If you are considering a water treatment system or any plumbing I highly recommend Dierolf. If there was a higher rating than 5 stars, we would have given it. From the sales person Matt, the office staff and most importantly the installation technicians Jon and Dave, the knowledge and professionalism has been outstanding. The work was done in a timely manner. The installation was clean and they made sure we understood our system, how it works, expectations, and their availability if any problems or questions. Exceptional is an understatement!

Great job installing our new water filtration system! Installers were very communicative and efficient. Well done.

David Arrived on time, explained the problem, the solution, and completed the service as well as necessary repairs. I will be having Diefolf Plumbing back again to perform regular maintenance and it also looks like I just found myself a new plumber!
