I've got a nice new chrome basin trap that comes with about a foot of
34mm waste pipe (chrome plated copper by the looks).
I need to do a 90 degree bend from this into standard plastic waste
pipe (32mm I think). Anyone know what might be the best sort of
connector for this? Can you get reducing elbows? Can I use a plastic
connector onto this copper?
Umm. Bad luck. I think both of mine are bodged with odds and ends of
plumbing bits. It will be chronmed steel or brass by the way.
Search until you find some thing that fits, almost, and then use car
body filler, layers of tape. silicone sealer or whatever to make up the
Some of the plastic waste fittings in the sheds come with a big chevron-section
rubber seals that will accommodate a range of pipe sizes. Used to be a problem
in the early days of plastic wastes with various proprietary pipes in both
metric and imperial.
There are two different British Standards covering plastic waste pipe. There's
the type that uses solvent-welded fittings and the smaller dia type that uses
push-fit fittings. The chrome waste pipe out of your trap fits the push fit
type, and you'll get a push-fit 32mm waste elbow at any shed. To connect to the
other type of pipe you'll need a compression coupling as made by Macalpine.
