What should I do if my water heater is leaking from the top?

Turn off power or gas, close the cold-water shutoff on top, and call CM Heating. Top leaks often come from the cold/hot inlet fittings, the T&P valve connection, or other top-mounted fittings. We provide diagnostics, repair, or replacement for tank and tankless units with 24-hour emergency service in areas like Everett and Bothell.

Quick steps:

• Turn off the breaker or set gas to pilot.
• Close the cold-water valve on top.
• Dry the area and note the leak point.
• Avoid tightening pressurized fittings.
