About us

At National Water Service, we set the standard for home water treatment, purification, as well as a complete line of well pumps, boosters, etc. In dealing with Residential areas, one of the important things a homeowner needs to consider is water quality. It is important to note that whether on City Water or a Well System, water quality can vary quite a bit from neighborhood to neighborhood. National Water Service is happy to do a basic analysis at no charge. And if extensive testing is deemed necessary, we have testing services available. National Water Service has been installing and servicing complex water systems in Restaurants, Hotels, Hospitals, Shopping Centers, and various other sites all over the the DC Metro area for over 45 years. We work with Architects, Builders, and Construction Firms to create custom applications for Water Treatment and Purification. Our installers are all professionally trained in both Water Treatment, Purification and well pump service.

My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone.

Original pump installed by them failed because spacers were not installed on the down pipe. Complex issue but they charged me for the repair claiming that the well had collapsed. A coupling was needed and that was not on the service truck. Made coupling from four pieces at the local hardware store. Another large charge. Pump failed two years later for same problem. This repair was done by L F Easterday, an outstanding firm. No failures since.
Response from National Water Service Corp
"I am sorry you had a negative experience, however when the pump was installed in 2008 a coupling was installed as well. The last time we serviced anything at your residence was in 2009 when you had a broken wire underground. I understand your frustration, but I do not believe we have been to your residence in almost ten years."
