Frequently Asked Questions
What should I do if my backflow valve is leaking?
When you notice water coming out of a backflow valve, the first thing to do is turn off the water main to limit water contamination and property damage. Call Safe Flow LLC and we will come to your home or business for service.
How to check a backflow valve:
Depending on the type of device, testing can be as simple as a visual inspection on some devices. Testing some devices requires the use of a precision reduced pressure valve test tool. However, we recommend having your local plumber perform backflow prevention testing and explain the best solutions for any problems identified.
What are the normal backflow preventer locations?
A backflow preventer is most often installed where municipal or well water enters the home. Another popular spot for a backflow preventer is at an irrigation system’s intake point.
