How easy is it to fit one of these and where can you purchase them from. It appears that my filler loop has jammed shut as I am unable to equalise the pressure on the system and have had to back fill it via the radiator valve to get pressure back into the system.
Sorry, I was not very clear on the question. The bit that is causing the problem is where you stick the T key in. There is no water going through on this system.
