February 1, 2023

If you have a backflow preventer in your home, it is critical that you understand how to properly maintain it. Backflow preventers were created to curb the start of backflow in residential structures, industrial buildings, and commercial facilities. Backflow occurs when liquid flows in the opposite direction in which it is supposed to. This guide will provide you with some maintenance tips for your backflow preventer.

Backflow Preventer Maintenance Tips

Before we discuss how you can properly maintain your backflow, you should know that backflows aren’t just something that you should ignore. It is a huge issue that anyone can deal with at any time. Knowing this information, it is smart to install a backflow prevention device properly. But, of course, you can’t do it on your own unless you are a professional. You must hire a licensed plumber.  

Here are some backflow preventer maintenance tips to keep in mind if you have one in your residential or commercial building, or you plan on having one installed:

  • Ensure that your device is installed at least five feet or lower from the ground. With this amount of space, it can ensure adequate testing, repair, and maintenance without jeopardizing the tester’s safety.
  • A platform installation can come in handy to reduce the risk of injuries to the professional tester.
  • Inquire if a strainer is installed upstream of the device. You can ask a licensed plumber for this information. Strainers are a must-have in keeping debris from accumulating in your system and causing damage. The strainer will also allow the system to perform more efficiently.
  • The best way to minimize or avoid pressure altogether is with correct installation. Pressure reduction inside the device can cause water damage or a leak within the relief valve.
  • Ensure that you have the correct size drain pipe. Additionally, you must install an air break. Don’t be afraid to ask your plumber if these are installed properly. You’d be surprised by what you can learn just by asking questions.
  • Your backflow preventer should have enough space and distance from the ground and leeway for inspections, field testing, and maintenance. Having adequate space ensures that test cocks are attainable.
  • Don’t be afraid to ask your plumber during installation whether the device will be installed horizontally or vertically. Vertical installation can cause the check valves to malfunction during back pressure. This means that your preventer should be installed horizontally for maximum efficiency.
