What should I do if my Ruud Ultra Plug-in Heat Pump with HydroBoost (120V Shared Circuit) has a relief valve producing popping noise or draining?

CAUTION: For your safety, always consult the manual or a professional before attempting any fixes.

Possible Cause: Pressure buildup caused by thermal expansion in a closed system.
What To Do: This is an unacceptable condition and must be corrected. Contact the water supplier or plumbing contractor on how to correct this. DO NOT plug the relief valve outlet.
