These will be next to each other.

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.

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.

I did exactly that.

But I made the trap out of 50mm elbows and tees (2 tees with a cap on
the top of each end to allow for cleaning).

Works rather well.

However, I find that it was a good idea to do this:

A B

The dip is 2 x 45 degree bends end to end. It is not much but it stops
back pressure from stand pipe A pushing back up B

I also finished A and B with screw caps so if either is not used it can
be blanked off.

****ing hell, another one of those complete obscenitys of a picture
with very little contrast between the item and the background.

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.

I did something similar --- I think you advised me here.

We have exactly as per your diagram. TW's idea of tees with screw caps
for cleaning would seem a useful improvement, provided they don't
leak. Ours haven't needed cleaning in the 15 years we've been here.

If ours leak, it will be in the dirt-bottomed crawl space under the
kitchen (which is accessible --- not pleasantly, but crawlable).

It's worked here for the past 32 years. The uprights are a machine-width
apart and the whole lot exits the room within the width of the second
machine.
