90 degree bend in polybutylene pipe within elbow

[tcarnell]

Hi all,

I was just wondering if anyone knows of a way to form a 90 degree bend in a polybutylene pipe without using an elbow connector.

The pipe runs in a floor void and will be hard to access once installed, so I wanted to eliminate a potential leak source if at all possible.

I vaguely remember a metal part that wrapped itself around the pipe to form a bend but maybe I'm mistaken...

All help and advice gratefully received.

Tony.

personally i would use a cement welded joint if done correctly no problem, can u not create an access panel for future service.

Can you solvent weld polybutylene pipe ??

The original poster did not say what size the pipe was nor if it was for water services, central heating, or a waste pipe

Thanks for that reply trying. I didn't mention that the pipe in question is a 15mm water supply pipe. Is it still possible to weld the joint?
No, it's not really possible to create an access panel. It runs behind a short run of floor standing built-in cabinets. It might be possible to access it by removing the plinth, but it might still be difficult to reach it.

You can either get a cold forming bend which will give a tighter bend than normal or heat it up with friction or hot air gun and bend the pipe.

In France you can get "shoes" that the pipe fits in for a bend this stops the pipe from "throating" or collapsing at a later date, don't know about the UK

This is exactly what I need. I knew I'd seen these somewhere before but wasn't sure they were for 15mm pipes.
Thanks again.

I think I get around 95% of my gear from toolstation, I just like the fact that you can see all the prices, good call.

me too, its like a info catalouge where you can work out best to solve problem, especially in the pan connectors.
cheap as chips too ie check out 25 elbows 15mm skrufix
