Test the tank's temperature and pressure relief valve
Every year, in April.
What to do
Lift the lever on the valve at the top of the tank briefly and let it snap back.
Why it matters
This is the only thing standing between a failed thermostat and a pressure vessel. A stuck valve is worth finding on purpose.
What to look for
- Water discharges when you lift it, rather than nothing happening
- It seals again cleanly when released — a valve that keeps dripping after the test needs replacing
- No rust or water staining on the discharge pipe, which means it has been relieving pressure on its own
Where this comes from
CMHC CE 47, spring. The water that comes out is scalding — stand clear of the pipe.
Catch it while it’s still maintenance.
