50mm OD push fit

[Crunchynut]

I need to do some plumbing and match into an existing installation. The existing pipe is a funny size  -  it is 50mm OD which made me think it is metric PVC pipe. But, it is using push fit fittings, whereas the only PVC pipe I can find is solvent weld.

 

Any ideas as to what I’m dealing with and where to get supplies?

 

(note 50mm push fit is 50mm ID / 54m OD as far as I know)

Yes I’d say you are dealing with just that. How about a converter? https://thepvcshop.com/products/metric-x-imperial-adaptor?variant=32666578714669
 

that place sell metric pipe at 50mm OD too if that’s what your after, and presumably the fittings to match.

More details of what you are joining to and what you want to connect to when you have found something that will fit your 50mmOD pipe?

 

That is not a standard UK size of pipe

Thanks for your replies. I’ve not go an issue with staying with 50mm pvc and solvent weld, and plenty of suppliers around. The concern I have is whether I can solvent weld onto the existing pipe. If it is pvc then no problem, but the fact that it is push fit  makes me wonder whether it’s whatever push fit is made of and you can’t solvent weld that. As @ProDave says, 50mm OD is non-standard in the push fit world, it seems. I guess I can do the tap test (tap fingers on the pipe - push fit sounds soft and ductile  and solvent weld more brittle sounding) to help confirm but access is tricky.

 

A rubber sleeve adapter from push fit to pvc may be the answer in normal circumstances , though I’m space limited so might not be an option.

This might help.
