Hi I have a Worcester 35CDi Combi Boiler that drops around 1/2 a bar pressure each week for the past 2 months. I keep topping it up expecting to see evidence of a leak but nothing so far. I have checked the pressure relief valve is not leaking. I am a bit lost to know what to do next. I don't want to start pulling all my floors up until I can confirm it is a leak. It would be helpful if I could isolate it to an area.
Does anybody have any advice on how I could trace the issue/leak.
Many Thanks
