Water Heater Relief Valve: A Safety Guide for Milwaukee

What it does

If the tank builds too much pressure or heat, the relief valve opens and releases water to prevent a rupture. It is the most important safety component on the tank.

Why it might drip

A valve that drips occasionally may be doing its job because the pressure is too high or an expansion tank has failed. A steady leak means the valve itself may be worn.

Never cap it

The valve must be able to open freely. Capping or plugging a relief valve removes the safety release and can turn a water heater into a hazard.
