Thanks for comments. Before I ordered a new flange I had one last go, being liberal with the blowtorch and the spanner and the fitting came off, so gas and agile, you were right! thanks

Thanks for the help everyone. I'll grab one of those and hopefully it'll fit without too many probs If not I'm sure I'll be back on here pestering you all again ( :

thanks denso, that looks like it might work. It doesn't say, but presumable the top and side connections would be 22mm and I could just use a standard compression fitting on them?

Well this is not going well! I tried to use a connector, but like denso said, the opening was reduced to practically nothing so that was a no go. Can you actually get a surrey flange with a 3/4 connection to the cylinder? because I'd had a pretty good look and they don't seem to exist...

Thanks Pete, that makes sense why it won't budge. Seeing as already have the 1inch one (and will be a faff to return) is there such thing as a 3/4 to 1" adapter? I realise this will make the flange sit slightly higher up but it would make life easier....... THanks

Thanks for your reply Sooey. Well as you can see in the pics, the heat removed the top fitting, but I'm right in thinking that the other lower one shown comes out as well? because otherwise the flange ain't fitting... Just how liberal is it acceptable to be with the blowtorch? I'm a bit...

Hi, I'm trying to remove the fitting from the top of my hot water cylinder to fit a surrey flange to feed a new shower pump, but it is thoroughly stuck! I've put plenty of WD40 on it and left it to soak in for hours as well as removing all of the gunk/rust that was around the fitting, but...

The TRVs are relatively new, although I didn't put them on so don't have the fitting instructions. I'll redo the piping as per the diagram and hopefully it will work Thanks for your advice :)

Hi KB, thanks for your reply. Not sure I understand entirely what you mean. Do you mean where I've drawn the dashes showing 'removed pipework' that should be put back in, with a tee put in it? and then a little further along another tee with the return coming back into it? As it stands...

Attached (hopefully) are pics of the pipework for existing radiator as well as sketch of how things are. Hopefully it all makes sense. Have I done something fundamentally wrong with the way the pipes are? To reiterate what I've said before, all other rads in house still get hot then...

I'm out atm but I will take some photos tomorrow so hopefully it'll make more sense than my rubbish descriptions! I really appreciate everyones help and suggestions so far

Hi, thanks for the replies Still nothing. despite turning off all other rads. By hot and cold pipes I mean flow and return, And to elaborate, I teed off the flow and return, taken from either side of the existing rad, then took them off to the new rad, then connected them back to the...

Hi John90 I cut into the flow/return pipes but they were 15mm not 22. All the underfloor pipework was 15mm. And yes, both the valves at either end are on and they are both fully bled. I will try what you suggested about turning off all the others, but suspect that as they are currently...

Diy teething problems... Hi, I added a new radiator to the system on the ground floor. I: Drained the system Cut into the hot and cold pipes running away from an existing rad Connected them up to the new rad Connected the new pipes back to the existing pipes under the floor However...
