Noritz Expansion Tank Replacement in Greater Vancouver
Genuine Noritz expansion tank, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Expansion Tank on Your Noritz Boiler
The expansion tank (expansion vessel) gives heated water room to expand, keeping system pressure stable. A waterlogged or failed tank causes pressure swings, repeated relief-valve discharge, and short-cycling.
On Noritz systems — including models such as EZ Series, NRC Series, NRCB Combi — a failing expansion tank often shows up as error 10 air supply or related symptoms. We diagnose it precisely and install the correct genuine Noritz part.

Safety Warning
A relief valve that drips whenever the boiler heats up is usually a failed expansion tank, not a bad valve.
