Boiler Loosing Pressure Around Half a bar Every 3 days? Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[Not stupid]

Hi all

My boiler, logic, is losing pressure, about half a bar every 3 days.

House is new build (10 years old) with 10mm drop plastic pipes to rads

Cant find the leak as all the pipes are in the joists so nothing visible in ceiling.

Nothing visible in the boiler

No air in rads

Open / hoping for any help or suggestions.

Thanks

Hi notstupid
Either you have a leak - in which case try adding leak sealant to your system. OR your pressure vessel has failed and needs replacing. OR your pressure relief valve is faulty. Or, or ,or .... there’s probably plenty more.
