Chrome pipe waste

[stevie12345]

Hi i'm currently plumbing in a new sink which has a chrome waste trap and pipe. Unfortunately I've just noticed that the chrome pipe is 30mm not 32mm and so the rubber ring for the 32mm compression fitting just falls off and even when I tighten it up the pipe is by no means water tight. THe chrome pipe fits snugly in a solvent weld fitting (in the end that normally slides into joint. I presume i couldn't attach it in here with solvent weld? Could i just put a layer of sealant around it and fix it with that? Is there a better way of doing it? Thanks

You can't use solvent weld it is not a glue it actually welds the two bits of plastic together so will not work on metal.
Have a look at the link if you or a good plumbers merchants can't come up with the correct adapter then contact McAlpine directly with the external diameter of your piece of pipe & they will have something, they always do.
Don't try to bodge-it it ends in tears.

I don't know if this is the case but in the past when I have fitted chrome traps, the supplied length of pipe has a different diameter at each end, the smaller to go into the trap and the 32mm end to go into your waste pipe compression fitting.

Hi thanks for replies. Unfortunately it's the same size all the way along. Been to plumber merchant and no help! hmmm

I read on here that when this happens and you don't want to put a compression coupler in the wall, you just wrap ptfe around chrome waste until a 32mm solvent weld coupler fits it and then do as normal..use solvent cement.

Have not tried it yet though

Try a poly pipe m+f push fit elbow. They have a large multi fit seal inside.

Yep that's the way to do it! Could buy them in b&q. Put elbow in wall and tile upto it, push in chrome And then slide bezel over it! Sexy as oot!

Hope this helps just pulled vanity out in guest bed for the pic.

can you not just buy some 32mm chrome pipe and use that instead of the 30mm?

Hi apologies for the delayed response. Thanks for all your suggestions. Would something like this be suitable: FloPlast Conversion Bend 32mm | NoLinkingToThis# or would it have to be the polypipe version? If it's still not sealed fully is there anything that would be appropriate to pack it out with? Thanks

The inside of the female end should have a rubber flange that is about 3.5mm deep, so u shouldn't need any packing. I think that I had a late night adventure to b&q to find one. Take tube as u can try before u buy.
