Expansion Tank Repair and Installation

What an expansion tank does

An expansion tank provides a place for thermal expansion in systems where heated water increases in volume and system conditions require accommodation.

Signs of an issue

Pressure-related symptoms, unusual water heater behavior, or a visibly damaged/leaking expansion tank can indicate evaluation is needed.

Installation considerations

Sizing, system configuration, connection location, and manufacturer requirements matter when installing or replacing an expansion tank.
