done a job today changing a rad on a primatic system, wouldn't have taken it if i'd noticed before pricing it!
so drained down (after 1.5 hours!) changed rads and filled back up slooowly. The pump is a high point (no vents) in the airing cup wedged between the cylinder and wall making it unbleedable!, how it was installed i do not know. anyway i couldn't get the heating going and i havent got big enough balls to boil airlocks out, dont even know if the pump is airlocked but am assuming. so any solutions or just some ideas or help would be greatly apprieciated as im half tempted to just not go back there and turn my phone off! ps never filled a primatic system before until today.
