why is my backflow preventer leaking water

Plumbing

The answer to 'why is my backflow preventer leaking water' is that a leaking backflow preventer is often caused by a worn or damaged internal seal or gasket. This can happen over time due to normal wear and tear, or it could be caused by debris or mineral buildup in the device.

Some common symptoms of a leaking backflow preventer include water dripping or seeping out of the relief valve or the body of the device. In some cases, you may even notice water pooling around the base of the backflow preventer. If left unchecked, a leaking backflow preventer can lead to water damage and potential contamination of your home's water supply.
