Certified Backflow Installers

Backflow Certified Testing, Replacing, and Installing Services in MD & DC
Master Plumbing is the company to contact if you need certified backflow testing, repair, replacement or installation in the Washington Metro area.

People throughout the Washington Metro area can make great use of a backflow device. For those who may be unfamiliar with them, backflow valves are safety devices that help to keep your drinking water clean. They do this by keeping contaminants from getting into your drinking water, which therefore makes the water safe for consumption. These devices can eventually run into problems, however, so it’s important to stay on top of those problems before your drinking water is put at risk. This means proper testing of backflow devices is needed and, if there are serious problems with them, getting them replaced is a must.

Testing of your backflow device should be done annually to ensure that problems are identified early if they are present. You’ll need to have a licensed & certified backflow professional test, repair or install your device.
Master Plumbing is the company to contact if you need certified backflow testing, repair, replacement or installation in the Washington Metro area. With more than 40 years of experience providing plumbing services to our clients, we’ll properly assess the condition of your backflow device and get you set up with a new one, if needed.

What Sets Us Apart?

See What Our Customers Are Saying...

  • I was referred to Master Plumbing and Mechanical by a neighbor and couldn’t have asked for a better experience! Kevin was not only prompt, friendly and courteous but he was respectful of my home (covering his shoes), extremely knowledgeable and instantly identified the problem. He explained everything he was doing and answered all of my questions. He really took the time and care to ensure my comfort and satisfaction. I was so happy with this referral, I plan on telling everyone I know about them!

    - Jessica Fonoroff
  • Master Plumbing has been to my house twice now, and I'm already a diehard fan. Steve is on-time, covers his shoes to make sure no dirt is tracked in the house, and neat as a pin. Also efficient and highly professional. On the second visit, he was able to determine that a faucet he installed was faulty. He promptly bought another one and did not charge a cent for the visit, new faucet or work. I very much appreciate his honesty and fine work.

    - Wynne Cougill
  • Very pleased with the work done. I called them to replace two hose bibs/outdoor spigots. They were pleasant on the phone and scheduled me quickly. They charged a fair price and the two plumbers were extremely thorough in fixing the issue. They took their time to explain my options and walk me through the pros and cons of each.
