604-359-1081 — book a diagnosisWhat the expansion tank does
The expansion tank absorbs the pressure change as system water heats and expands. A waterlogged or failed tank causes pressure spikes, dripping relief valves, and stress on the whole system.
Signs it needs replacing
Pressure climbing above 30 psi when hot
Relief valve weeping or discharging
Pressure swinging up and down
A tank that feels full of water when tapped
