Suburban tank water heater P/T relief drip or lost air pocket

Use this when a Suburban tank water heater weeps or drips from the pressure-temperature relief outlet during heating.

Owner-safe checklist

• Turn the water heater off and let stored water cool before following Suburban air-pocket guidance.
• Record whether the P/T relief outlet drips only while heating or continues after cooldown.
• Do not cap, plug, restrict, or ignore the relief outlet.
• Have a dealer or qualified plumbing/RV service handle persistent discharge, valve replacement, or accumulator work.
