You got it. This is the overflow from the cisterns. Filling heating system and then water starts coming through ceiling. Ball valve stuck and going down overflow and pouring out of the fittings over the pump, shower pump mv

Shocking isn’t it.

Dam, I thought it was the clips screwed into the CWSC to hold the 22mm in place. & why did they make it so difficult for themselves by using comp gate valve when there are push if versions.

Clips just floating

Oddly, tho it would have been so much cheaper to do it in copper! Ahh, forgot. That requires skill

I know, how bizzare!
When I saw that in the orig picture it made me laugh out loud like some nutter!

 

[mutley racers]

I wasn't laughing

Lol.

So i have been searching the forum for ways to connect copper to overflow and some say JG speedfit. Others recommend irons to overflow and irons to copper. Another recommends compression coupler with imperial olive on overflow.

If JG works I would have thought the hep would have.

It should seal as it's 21. Something mm

 

[Deleted member 96286]

That's an easy one. There's an iron lying idle in the airing cupboard, when it should be getting put to good use by the lady of the house doing her woman's work. Simples

I've put 22mm into plastic screened overflow tank connectors before now (only way I know of if you're using a Bylaw 30 kit). It was tight but, being on gravity only, it sealed okay.

Logically the 3/4" olive approach (wrapped in PTFE), much as you'd connect to 1/2" alkathene, should work, but I would worry about the lack of pipe insert. That said, rigid pipe won't be out of round...
