i am doing a central heating job for a friend and have finished everything up with no leaks in the pipe work, but the boiler is losing pressure and as a result there is no central heating OR hot water. i checked the expansion vessel and pumped it up with a foot pump, still no pressure and no water leaking. i am clueless as to what the problem could be, i have a glow worm technician coming out later in the week but would greatly appreciate any ideas from anybody in the meantime, so i could have a shot at fixing the problem myself. thanks.
