Must be 1 1/4 pipe, try getting an imperial olive, or nip it up, undo it then ptfe on the olive, not the thread

yes brass fittings ! but if you go in the shop and say 28mm compression male iron or female iron , they will know what you mean !
it doesnt mean Iron fittings !
its just the way I say it I guess ?

Iron means it’s threaded, you would have to ask for an malleable fitting to get iron rather than brass in the merchants I use

28 will go onto inch with a bit of persuasion

Here's a few photos of what I've found...
I'm not sure how we were getting any hot water at all really!
Cold water inlet,
Boiler feed to the coil,
This is the collection of junk that held the cylinder up for nearly 40 years!
Yep all those bits were wedged in underneath including the iron pipe fitting!
Cylinder in place on it's new stand, that took 2 hours too build on it's own due to three different levels to work off!
I might get a bit of ply under it yet.
All this is temporary too! I'm getting a new 200+ litre cylinder installed in a few months time along with a nice new Grant Vortex Pro boiler.
The reasons I'm not just fitting the big cylinder now is that,
1 Not sure the old gravity boiler can heat it!
2 The 4" kitchen ceiling joists won't hold it!
3 The new 7" joists I've just fitted are under the two header tanks that need moving but not yet.
4 I don't want the new permanent cylinder full of the ****e you see in the top pictures!
What a PITA!

Just wanna say, what a great forum/bunch of people, so often I've seen posts like this on Diy type forums and the replies are 'don't touch it' etc.
I guess that some plumbers/heating engineers don't wanna give any tips away for free?
Sorry that I can't give any advice on this one, I'm currently waiting for a new pressure diverter valve to come for my boiler, I stripped and used the repair kit on the current one but no joy.
My boiler is a Baxi 105e, what a pig to work on, really tight spaces, not looking forward to getting that valve off again but hey oh.

That reminds me when I had to replace a leaking auto air vent on my Ideal boiler, It was right at the back & couldn't get the water pump pliers on it to loosen it. So I screwed a jubilee clip around it which gave me something to grip onto it & remove it
How you getting on @dobbslc? Have you sorted out your problem?

I’m happy to advise on anything except gas or flues, regardless of people’s view of the law I’m not being responsible for someone hurting themselves or others
105e is a great boiler, first of the decent Baxi combi’s
Oh yeah, I totally agree about the gas aspect, that's pipework I won't touch,......on some of those forums, some engineers try to discourage folk from even tackling a water based or electrical fault by saying that it's illegal to even remove the cover off a boiler unless you are gas safe.

You have hot the nail on the head, most covers these days are cosmetic but some are combustion seals and some are depression chamber covers. I would always ask what the boiler was and go from there

My thoughts also, I would rather call in an expert, Than risk anyone's life

The longest day.
Two 12 hour plus days and it's now working! I'm totally knackered!
Spent a lot of time messing around finding the right size fittings to convert from the old imperial pipe to metric. The coil pipe unions on the old cylinder were positioned one on each side of it so I had to reroute everything to new positions to fit the new one where they are one above the other
.
There were lots of small take offs for the heating system that needed to be T'ed off the 28mm pipework and it had to make new overflows for both header tanks!
The most ring shrinking moment was soldering a reducer to the old vertical 35mm or 1 14/" pioe to convert it to 28mm pipe
I had to use an end feed fitting in the vertical position and wasn't to sure about how well it would take.....
Spent an hour filling the system running round looking for leaks and so far I've found one on a 28mm compression fitting that I nipped up and seems ok. I have air locks in the radiator pipes but that's the same as every other time I've drained it down so tonight ill go round shutting off various rads to push the air out.
I'm off to work now for a rest!
