Signs of Gas Valve Failure
The boiler fails to fire (no gas flow despite ignitor working), the boiler fires weakly with a yellow or lazy flame, the gas valve makes a clicking sound but does not open, intermittent operation where the boiler sometimes fires and sometimes does not, or a gas smell near the gas valve.
Why Professional Replacement Is Required
Gas valve replacement involves: working with gas under pressure, disconnecting and reconnecting gas piping, pressure testing for leaks, adjusting the gas pressure regulator for correct manifold pressure, and verifying combustion with a flue gas analyzer. Only licensed gas fitters should replace gas valves.
Replacement Cost
Boiler gas valve replacement costs $400-800 including the valve ($200-450 depending on brand) and labour ($200-350). Navien and Viessmann gas valves are typically more expensive than budget brands. Emergency same-day replacement available.
