Rinnai Flow Sensor Replacement in Greater Vancouver
Genuine Rinnai flow sensor, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Flow Sensor on Your Rinnai Boiler
The flow sensor measures domestic hot-water flow so a tankless or combi unit knows when to fire and how hard. Scale and debris are the usual enemies, causing no hot water or false activation.
On Rinnai systems — including models such as i-Series i090, i120, M-Series — a failing flow sensor often shows up as error 11 no ignition or related symptoms. We diagnose it precisely and install the correct genuine Rinnai part.
