Boiler Loosing Pressure Around Half a bar Every 3 days?

Postby Not stupid » Fri Feb 05, 2021 5:21 pm

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.

Simply Build It

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.
