Genuine Noritz three-way diverter valve, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Three-Way Diverter Valve on Your Noritz Boiler
The three-way diverter valve directs hot primary water either to the heating circuit or to the hot-water plate exchanger. When it sticks you get heat but no hot water, hot water but no heat, or radiators warming when you run a tap.
On Noritz systems — including models such as EZ Series, NRC Series, NRCB Combi — a failing three-way diverter valve often shows up as error 10 air supply or related symptoms. We diagnose it precisely and install the correct genuine Noritz part.
