Yes, you can use a repair kit from a different brand on your backflow preventer, but there are important considerations to ensure compatibility and effectiveness. First, verify that the repair kit is designed for the specific model and type of backflow preventer you have.

Some high-risk facilities may require more frequent testing, as specified by local codes or regulations. Regular servicing includes cleaning, checking for wear and tear, and replacing any faulty components.
