Boiler or nearby piping is leaking water

Safety first: Hot water can cause burns. Turn off power and allow system to cool if leak is significant.

• Identify source: Dry the area and observe where water reappears—relief valve outlet, joints, air vents, or boiler body.
• Relief valve: If water is dripping from the relief valve discharge pipe, check system pressure. High pressure may indicate a failed expansion tank.
• Tighten fittings: Gently tighten accessible unions or threaded fittings if they are seeping.
• Replace faulty components: Automatic air vents and relief valves are replaceable; ensure replacements match Pennco specifications.
• Boiler body leak: If water seeps from boiler sections or casting, the boiler may need major repair or replacement.
