ok ive just refilled and bled the rads again and turned on the CH & W ill go take a look at pump again. at present its on the III and 36w

ok so ive turned everything off and have started to drain the system again as mentioned previously, the ballcock dropped and then it started to fill the F&E tank back up, ive hung the ballcock up and turned the refill valve off and the F&E tank is draining down, ill give it another clean and...

All pipes apart.from.cold.feed from header are hot on the heating side in the cupboard Some of the upstairs radiators are now starting to get a little warm? how long should it take to get hot? ive cranked heating up to full? or should i drain down and back fill again?

Went around bled all rads water coming out of them all, I've put heating and water on heard a few gurgling noises but don't appear to be getting heat to radiators? Here's a close up of pump, I did notice boiler fired up for a bit then went back to pilot setting as well?

will do and thanks everyone for the help so far it is really appreciated and its helped me feel a lot more confident going forward with issues like this, hopefully this will have sorted it out short term, will know more this evening.

Yeah i hadnt opened the outside tap fully as i wanted to also check for leaks, i havent had time to check it last night or this morning but a lot of air did come out of the system whilst backfilling it yesterday, ill go around al lthe radiators again when i get home and bleed them, after should...

Update, got home, put 22mm push blank on Pipe (A) (Feed Vent) connected downstairs rad to hose and outside tap, ive turned water on and waited nothing for about 10 mins the F&E was not getting any water to it, then i started down stairs and bled each individual radiator in turn loads of air came...

When you say trickier in what sense, as the cold feed comes straight down the wall into the bend - air separator, so could i not cut the pipe slightly above the bend ? Then as you say if its blocked further up the pipe i can cut the section out? my only worry is how to clean the separator...

I will when i get home, isn't that the feed to the boiler? as the one on top is upto the F&E feed vent pipe and then the next one is to the F&E outlet and the one below your arrow is to the pump ( or is that just a picture to show where to measure )

Thanks when i tested with a magent it only seemed to stick / get attracted to the pipes very close the separator? so if i cut close to the separator then how do i clear it out as wouldnt i just dislodge anything and 'move it further around system, or if that is the purpose should i then had some...

Didnt get chance last night to try the block feed off and backfill, but had a thought about if i needed to cut the air separator out. Would another option be to cut the 4 pipes ( think they are 22mm) and clean out the Air Separator/Pipe work then re attach it using compression connectos...

Just thought it would be easier, more flexible, i open to suggestions, i dont have skills or tools to solder. Here's a pic of the current air separator taking leaning over the cylinder. Another option im guessing would be to cut the 4 pipes ( think they are 22mm) and clean out the Air...

Hi may have to cut my copper pipes going to my air separator as it appears bunged/clogged up, if i do this ill have great difficulty fitting copper back due to the limited space, could i use this type of pipe with either push on or compression connectors...

In the pictures in #13 can you tell me (if you can) if the 4 pipes going to/from the air separtor are 22mm ? and one of them that connect to the bottom of the pump can that be unscrewed from the pump instead of cutting? im just looking at the worst case that air separator needs cutting out and...

Yes i just use the bleed key to open close that drain valve, every radiator in the house has this on them, i have three radiators where i cant open these valves for various reason (to close to wall, one is rounded plug valve and the other the pipe is dented so the bleed key wont fit in) but i...

Not being familiar with you radiator valves I’m assuming you have to remove or unscrew a plug inside the drain off spout while the main valve is open in order to get the mains pressure from the from the hose to enter. If you look at the picture in post #6 where the water is coming out that is...

Great now i understand what im 'trying' to acheive, tonight after work ill manually take some water out of the F&E tank as its full, and block off the feed pipe (A in the drawing right?) and then ill stick a hose on one of the downstairs radiators and see if it forces water up through the outlet...

i didnt see the water rise or notice any bubbles so id say no but cant be 100%

ive just been in garage to check boiler and noticed a drain vent above it on one of the pipes ?? that surely cant be the drain valve as its not at the lowest point

What do you mean by that statement. When i got home this evening the rads had no water a couple had some air in but not as much as last night. I connected a hose to the downstairs radiator and connected that to outside tap and cranked it open, went into loft and waited for about 10mins for the...
