Backflow Preventer Testing & Repair in DC & MD

Your backflow preventer is one of the most important aspects of your building’s plumbing system in the MD or DC area—it’s designed to prevent dirty or contaminated water, commonly from sprinkler systems, from being siphoned back into your potable water supply. In addition to lawn sprinklers and irrigation, backflow preventers should be installed in swimming pools, dishwashers, washing machines, hose bibbs, and anywhere else where contaminated water is at risk of ending up in the clean water.

However, if your backflow preventer isn’t working properly, you could be putting your potable water at risk. The expert plumbers at James A. Wheat & Sons can test your backflow preventer to ensure it is in perfect working condition—and if it isn’t, we can do the necessary repairs to fix it.

Schedule your backflow preventer testing or repairs today by calling 240-399-5051 or filling out the form in the sidebar.

Why is backflow dangerous?

Backflow, caused by cross-connections between clean and dirty water supplies, can contaminate the potable water supply in your building and potentially lead to serious illness if consumed. In fact, over the past decade there have been numerous reports of backflow causing potential problems, including:

  • A cross-connection aboard an Alaskan crab processing ship resulted in backflow of sewage that caused 189 employees to get sick and also endangered about $35 million worth of processed crab.
  • Copper sediment got into a beverage mixing tank and caused four people in a residence hall at a university in Michigan to get sick.
  • Carbonated water back-pressured into the potable water supply through faulty check valves on soda dispensing equipment in a San Antonio lounge.
  • At a large public meeting facility and sports arena in Seattle, bright blue water was flowing from drinking fountains in the lobby and sinks in the concession area. Several people reported general nausea. The pressure of the carbonation equipment far exceeded pressure in the water main.

Ensure that this never happens in your building—schedule your backflow preventer testing or repair today! Our professional plumbers can help you keep your potable water safe and healthy.
