boiler pressure

I'd be looking for a leak somewhere at the first instance...
 
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
 
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??????
 
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.
 
Id be checking the Pressure Relief Valve is not letting by.
