Frequently Asked Questions
What does a purge valve do?
A purge valve is used to get air out of a given system. Sometimes when water or refrigerant flows through pipes or coils, air can get trapped and cause excess noise or even damage. The purge valve removes the air and keeps everything running smoothly.
How do I test a purge valve?
Always start by turning off the system and closing the valve so the section you’re working with is isolated. Then, open the purge valve to let out air. You’ll be able to hear the hiss of air escaping. Once you get a steady stream of fluid, the air has been purged.
How do I bypass a purge valve?
We don’t recommend bypassing purge valves because of the role they play in keeping systems running correctly. If you need to bypass the valve for troubleshooting purposes, close it and isolate the section of the system it's responsible for.
What causes a purge valve to go bad?
Corrosion, debris buildup, or seal failure caused by wear over time. Regular exposure to water, especially if it is hard or has a high mineral content, can cause it to degrade especially quickly.
