What is Backflow Testing?

One of the most severe issues that can happen with plumbing is a backflow malfunction. The crucial device which separates wastewater and clean water lines can break during severe changes in water pressure. If the backflow fails for any reason, you risk contaminated water leaking into the clean water supply. Any leaks related to the backflow can cause serious concerns for human health, so it’s important to test for backflow issues every year.

The Importance of Backflow Prevention and Testing

Chances are good that homeowners don’t think much about their backflow assembly. The small device helps separate the clean water flowing into the building from the dirty water leaving. No one wants to drink dishwater, but that’s what happens if there’s an issue with the backflow assembly. A problem occurs when there’s a dramatic change in water pressure, such as when a pipe breaks or the main water line clogs. This change in pressure is something the backflow can’t handle, and it allows wastewater to seep into the clean water lines. Wastewater can be anything from what goes down the sink to what goes down the toilet, so definitely nothing anyone wants in their water supply.

What the Testing Process Involves

The testing process for backflow issues is relatively straightforward. A licensed plumber will shut off the water for about 15 minutes. Then they will use a variety of test kit hoses that connect to meter reads. The plumber will check each test kit to make sure they’re reading a ‘normal’ pressure level, which is a number that varies depending on where the plumber is testing. If all the hoses read at correct levels, the plumber can sign off on the backflow assembly! If anything is wrong, the assembly can be replaced in its entirety, or further testing can be done to determine the exact issue.

Prevention Options for Backflow Assemblies

Having a trusted Sin City Plumber come out and test the backflow assembly every year is the easiest way to prevent backflow issues. A licensed plumber with backflow experience can also install a safety device that helps regulate water flow in the event of a pressure drop. These safety devices need to be installed correctly to be effective, and testing should still be done every year to keep the assembly in good shape.
