My backflow preventer sometimes leaks water from a relief valve. Can I remove or plug the valve to prevent water loss?
The relief valve is installed to prevent water pressure from building up too high when the water in a water heater expands. The relief valve can be replaced with a small expansion tank that does not leak. Plugging or removing the relief valve, however, could cause damage to your water heater or plumbing.
