Boiler losing pressure?

[tekinew]

Hi M8s

Had the boiler fitted today, Worcester Bosch combie, plumbers left with Boiler losing half a bar in an hour when idle. Seems to be holding pressure when running.

Plumbers said telephone if this continues. All joints seem to be sound no water evident on downstair ceilings.
Any ideas?

Turn the boiler off first and make sure it has had time to cool down.
Pressure the system up then isolate the flow and return. Do not use the boiler for a while.
Watch the guage to tell if the leak is coming from within the boiler or from the system

Woke up this morning to a damp patch on the downstairs ceiling. Lifted floorboards and found a leaking joint. Water running along the length of the ceiling and thankfully not holding in one spot. Plumber came back and repaired.

He obviously tested everything well before he left then
