What 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.

Mission Coverage
Mission & neighbouring Fraser Valley
Mission's hillside homes north of the Fraser and rural Stave Falls and Hatzic acreages often need carefully sized boilers and, on rural lots, propane conversions. We handle both modern condensing installs and retrofits of older Fraser Valley systems.
Approximate installed price (part + labour). A diagnosis confirms the fault and the exact part for your boiler. Call 604-359-1081 for an exact quote — we fit the part, we don’t sell parts over the counter.
