Likely causes
- Normal pressure loss over time
- Radiators bled recently
- Leak on the system or a passing pressure relief valve
- Expansion vessel has lost its charge
What you can safely check
- Top up through the filling loop to between 1 and 1.5 bar when the system is cold and close the loop fully afterwards
- Reset the boiler if it does not restart on its own
- If you are topping up more than once or twice a year, the system is losing water and needs looking at, so call us
What our engineer does
If the pressure keeps dropping we find the leak, test the expansion vessel and pressure relief valve and put it right. Anything involving the gas supply, gas valve, combustion chamber, flue, fan, PCB or heat exchanger must be left to a Gas Safe registered engineer and must not be attempted by the householder.
