There is very little room behind these appliances and was wondering how
practical it is to have a common waste system.

Are there any regulations on the horizontal length of the U trap, such
that I can make a combined trap for both. I would use 40mm pipe,
possibly solvent weld.

This diagram will only work with fixed width fonts.

Use one of these

most plumbers merchants have them.

Many thanks.

I have seen similar, but I suppose I'm rather used to hoses loosely
placed in a vertical waste pipe, rather than to a push fit attachment as
in your link.


The good thing about pushing a hosepipe onto the spigot with a jubilee
clip over a hosepipe pushed into a 40mm waste pipe is that if there is a
blockage downstream, it does not overfill past the open end of thje 40mm
pipe and flood the floor, buy stays within the machine concerned.
