Where Water Heaters Leak in Chelmsford

Dripping relief valve
The valve opens at 150 psi or 210 °F. A steady drip means a worn valve or a pressure problem.

Weeping drain valve
Plastic drain valves wear out. A new brass valve usually ends it.

Water from the tank body
Rust and water at the seam or base mean the tank has corroded through. That one gets replaced.
Leak at the expansion tank
The small tank on the cold line, or its connection, starts to drip.
Rust-colored water
Rusty hot water or rust streaks on the tank can mean corrosion inside.
Tank seam or bottom leaking
Water from the steel tank itself, the one leak that means replacement.
