Hi all first post so be nice, I took a radiator off to flush it as it would not work / bleed. I put it back on and since then the radiators would not get warm, ive bled them all about 20 times each over the last two days, ive tried draining the system but the header tank remains full (ive turned off the refill valve and hooked the ballcock up just in case) i have managed to back fill the header tank or at least get water to come out of the overflow from a downstairs radiator connected to a hose and the outside tap, but still the header tank wont fill back to the radiators or empty. Ive just been around them all and drained and bled them again or at least the ones that could be drained, the upstairs didn't have any water in them. The system appears to be blocked somewhere although when backfeeding it gets water through? ive vented the tank (well i opened the bleed valve but nothing came out) Ive also got two radiators that still have water in as i cant turn the drain valve on one as it appears rounded and the other wont accept the bleed key (wont fit in the hole to valve)? ive tried loosening the screw but they are very stiff and im afraid to bend the pipework connecting them to the radiator and causing a leak / further issues.
Ive been around the system again this morning (07/04/24) and bled the radiators, all the downstairs ones had air in the system and after bleeding the first two (furthest away ones) i heard a little gurgling and water in the pipes, but nothing apart from air came out, again the one downstairs radiator had water in it (as mentioned above) upstairs nothing came out of any of the radiators, no air or water.
Any help much appreciated.
