I recently had to replace the prv on this boiler and now find that the pressure keeps dropping and rising to 3 bar, just short of where the prv should blow. I think that I need to do something to the expansion vessel with a pump but there is nothing in the manual that I have. Is this something I can do and can anyone tell me how?
Thanks,
Frosty
