I have replaced the the CH flow sensor (34) but it will not fire at all then? It is reading approx 1.2k!!! At room temp?? I had another and that reads the same?? I also swapped the CH and HW over over and HW is still fine/no problems at all? Also looking on page 29 the as temp increases then...

That is rough!!

The thermostat on the boiler to set the CH is also ok. But even when I have it set at at its lowest in order to call for CH the outlet pipe is gets absolutely red hot. I can not keep my hand on it! It’s the internal ‘heat exchange limit thermostat’ (50 on diagram) that is switching the boiler...

Hi all My trusty Ferroli 701CH is switching on /off. I checked the LED status and done a few basic with my multimeter checks and it’s tripping on the CH limit stat/over temp on heat exchanger. Would the CH flow temp cause this as it’s not adjusting/modulating the gas valve? I have tested...

How could you cut it to leave a thin flange? The Pegler type you ‘might’ be able to perhaps file it down level with OD of the pipe. I’ve replied with a better solution. Thank ls for the advice as this could be used when not using Danfos ones. Cheers

Little update. I went to LBS plum centre and they had Danfoss branded ones in packs of two. Much heavier and more solid plus they have a proper (grey) collar like normal pushfit and the super seals fit it perfectly. They are also cheaper then the Pegler brand from Screwfix that will not...

Yes I know that. But superseal/sleeve type inserts don’t fit. The ends are to wide and fat. Looks like you have to use compression type inserts as below.

Hi all Picked up 4 of these today ti fit to new rads. It’s all mainly JG 10mm with JG super seal (with rubbers) inserts in all connections. On looking at these it seems it is VERY tight to get a superseal insert on as it seems so tight as the insert it very slightly wider/pokes out more...

Looks like the leak is back? I could ONLY it to leak by directing shower head directly at the T&G panelling . I also ran the basin/bath constantly plus filled them both several times/emptied them and no water at ceiling. So confused now???

Did not have chance to post pics as leak was not from my repair it was from shower that has 250mm cladding. Looks likes it’s been fixed to battens behind at approx 1 ft horizontal. The tray is solid and smooth sunk in slightly. When I spray jet direct at the vertical joins it’s like...

The problem is there is now a 2ft gap between pipes when it cut out yet again. It was just one SV fitting. That failed. I then cut out about 1ft to get a new sort length of PVC and 2 couplers. Now I have to cut it again!! If I have to use compression couplers I would be doing just the...

Hi all I had a leak from a bath waste last year and it was found to be a coupler between new 40mm PVC to a grey PVC pipe. The white/new side from bath waste was fine but it was if the other side to the existing grey waste pipe had silicon on it and not solvent glue? Also there was ‘pressure’...

I managed to get it back in and like you stated if you do over tightening it it does effect the valve operation. All back and zero leaks (I had blue roll wrapped all around it). The boiler is still losing pressure though BUT I think it may be the expansion vessel as the pressure jumps about...

There’s no pressure there anyway. Only got HW. So the gland just pushes in and nut holds it? Want I do t get it that it’s has 1.5/2bar in it like that and was o my a very slight weep. I checked other rads lock shields and the nut definitely goes in there. I’ll have a play tomorrow if I get...

So the white bush part is not threaded? It it actually held in place by the brass bush I found? It seems way to much of a coincidence to find it with valve covers. I’ll check another old existing valve later and compare it. Cheers

I have some yellow gas tape. Never new it was thicker tbh, plus I always wrap correctly with thread. What I did find today on a window cill was this below. Is this not the ‘part’ that actually holds the inner ‘valve’ in place? Has it somehow been removed by someone trying to just open the...

I just find the the tails keep on screwing on the way in? I’ve tried with PTFE and still get weeping joints. Never tried adding paste as well though. Plumber I know stated 13 turns. The threads are so long on tails what part of tail is it best applied. Bit confused on last turn on the end...

Looks like Toolstation no longer do them? Are interference fits still available?? https://www.toolstation.com/angled-radiator-valve-cp/p15063 Cheers

So it is a 15mm valve. I really do not want to remove the ‘tail’ going into rad if possible. That’s what I meant by ‘interference’ fit’ just did not know the correct terminology just needs to be clean (some use paste). I have had a few valves from Screwfix recently and they have all had...

Hi all Been helping my Aunty who has jus minded into a property and it needs a lot of work. All rads were isolated except fir living room. I opened the rest and tapped the TRV to get them to open. I’m stuck on one lock shield, when I try to open it the whole valve comes out and it’s still...
