boiler pressure

gasman3555 · 18 Feb 2010

hi i recently installed a new radiator and now after 30 minutes my boiler loses pressure and ideas?

I'd be looking for a leak somewhere at the first instance...

I assume you've re-pressurised the system via the filling loop?

defo not a leak and bled the system over and over, the system has no trvs but i have put 1 on new rad could this be the problem

yes 1.5bar

Adding a TRV wont cause the pressure loss, if you are certain there are no leaks from any of the glands etc... maybe some of the pipes wewre disturbed at a place where its not obviously visible?

yes but i carnt see that as the boiler is located next to the new rad and the pipes all run up yhe garage and a leak would come threw the plaster board

would a leak not be noticeable??????

could it be the pressure vessel damaged when bleeding the system?

Bleeding the system wont do any harm to your Expansion vessel. If you are concerned it may be let some air out the valve, if it squirts some water out its toast.
