The answer to 'my backflow preventer is leaking' is that a leaking backflow preventer is a common plumbing issue that can be caused by several factors, including wear and tear, debris buildup, or improper installation. Symptoms may include water dripping from the device or pooling around the base.
In many cases, the solution can be as simple as tightening the connections or replacing a worn-out gasket. However, if the problem persists or the backflow preventer is not functioning properly, it's best to call a professional plumber to diagnose and repair the issue. Attempting to disassemble or repair the backflow preventer yourself can be risky and may even lead to further damage if not done correctly.
