Worcester 24i losing pressure

[timcunnell]

My Worcester 24i combi boiler keeps steadily losing pressure, and I am b*ggered if I know why!! As far as I am aware, the only possible cause for pressure loss is a leak somehwere in the system. Yet I have not been able to find any damp patches anywhere. Don't get me wrong, the pressure isn't falling at a dramatic rate - if I fill to 1 bar, this will drop to around 0.8 after approx. 7 days. Not drastic - but just rather worrying. Any help would be much appreciated!

Your pressure relief valve could be slowly passing to outside to check undo the connection under the boiler on the left hand side leading to the pipe that goes outside ,if water comes out then or over time (dish underneath ) it requires changing plus the auto air vent can pass slowly inside the combustion chamber and evaporate away

I recently went to a house with the same problem and there was no signs of escape from the PRV or anywhere else. He had just spent loads of money on laminate floor laid on top of his wood floor downstairs.






UNLUCKY!
