I'm about to embark on my first speedfit plumbing task, having always used endfeed copper before...
Anyway, I would appreciate some advice on how to bend the stuff?
Can you permanently deform it like copper? or does it spring back?
I've seen guidance saying you can bend it with a pipe bender, or a spring, but surely it springs back?
I've also seen the speedfix cold forming bend... does this bend have to be left permanently in place? The speedfit literature suggests you can achieve a much tighter bend radius with the former than just bending it and holding with clips?
Anyway, any advice would be appreciated. I'm keen to use longer lengths to save on fittings, and the potential failure of fitings in the future.
Also, if i'm running it across my loft, does it need supporting the whole way? or will clipping it to each roof truss (say every 600mm) suffice?
Thank you in advance.
