Boiler Pressure Gauge Not Moving
A stuck gauge may be faulty, or pressure genuinely isn't changing — both worth checking.
If your pressure gauge never moves, the gauge or the filling system may be at fault.
Common causes
A faulty or seized gauge, a blocked filling loop, or a genuine pressure problem can make the reading appear stuck.
What to do
A technician verifies actual pressure independently and replaces a faulty gauge or clears the filling loop.
Key takeaways
- A stuck gauge may be faulty
- Verify pressure independently
- Check the filling loop
- Replace a failed gauge
