Where Water Heaters Leak in Marlborough

Water from the T&P valve
A relief valve that drips or runs every day usually means a worn valve or too much pressure in the tank.

Leak at the drain spout
The drain valve at the bottom is one of the most common leaks, and one of the easiest to fix.

Rust at the bottom seam
When the steel tank itself leaks, no repair holds. This is the leak that means a new heater.
Relief valve dripping
A T&P valve that drips or runs, either worn out or reacting to high pressure.
Drain valve weeping
The valve at the bottom drips from the spout or around its threads.
Element or control valve seep
Gaskets behind an element panel, or the threads of a gas control valve, let water out.
