A backflow preventer is a critical component of plumbing systems that helps ensure the safe and clean flow of water by preventing contaminants or pollutants from flowing back into the main water supply. Backflow can occur when there is a drop in water pressure in the main supply line, causing water to flow in the opposite direction it is intended to flow. This can happen due to a variety of reasons. Two examples are a broken water main or a fire that uses up a large amount of water.
How To Prevent Backflow
To prevent backflow, you’ll want to make sure you install a backflow preventer valve. These valves are designed to close automatically when water pressure drops, preventing water from flowing in the opposite direction. Backflow preventer valves should be tested annually by a certified professional to ensure they are functioning properly. This typically involves checking the valve for proper operation, checking the pressure gauge, and checking for leaks or other signs of damage. In addition, the valve should be cleaned and lubricated as needed to ensure proper operation.
Backflow Prevention Testing Kits
We recommend the Diaphragm type instruments Model 845-5 and 835 with bottom and vent connection. Use for testing system differential pressure and checking assemblies used for back flow prevention. Backflow Test kits are also available in 2 and 3 valve models.
