What is a backflow? A backflow preventer is a device that is connected to your home’s pipes in order to stop the sprinkler water from flowing back into the main water supply. This prevents the water supply from being contaminated.

*Some backflow preventers must be tested by a certified plumber

How do you know if you’re due?  WSSC, other water authorities and manufacturers recommend replacing your backflow every 5 years.  Check the date on your backflow tag at your water service entrance, usually located in unfinished area of your basement.  If your home is in a county which does not require a backflow tag, then determine when your home was built to see if replacement is necessary.

 Realtors, is your client selling their home? Your building inspector will recommend this change if it is over 5 years old.
