Heater frequently shows small drips from the pressure relief or drain points when hot.

Safety first: Allow the heater to cool before tightening any drain or relief fittings.

• Check system pressure: Ensure there are no closed valves downstream causing pressure build-up.
• Tighten plugs: Gently tighten drain and inspection plugs; do not overtighten plastic parts.
• Replace washers: If weeping persists, replace sealing washers or O-rings on the affected plugs.

Persistent or heavy discharge indicates a pressure or flow problem that should be investigated further.
