Weil-McLain water heater or indirect tank is leaking water onto the floor.

Safety first: Turn off power and, if necessary, close the cold water supply to the heater. Hot water can cause burns; avoid direct contact.

• Identify leak source: Dry the area and observe where water first appears: from fittings, relief valve, tank seam, or sensor wells.
• Check relief valve discharge: If water is coming from the temperature and pressure relief valve discharge pipe, the system may be over-pressurized or overheating. Do not cap this pipe.
• Tighten fittings: For minor seepage at threaded connections, gently tighten with appropriate tools. Do not overtighten and crack fittings.
• Replace faulty components: Leaking relief valves, gaskets, or nipples should be replaced. If water is seeping from the tank body or welds, the tank is likely failed and must be replaced.
