Frequently Asked Questions

How do I know if my bypass valve needs replacement?

Signs of a failing bypass valve include water leaking from the water heater, inability to pressurize the system, or water spraying from relief valves. If you notice any of these issues, test the valve or replace it to restore proper system function.

Can I use this valve for winterization?
