This is a bit of a repeat of a thread I did a while back, it's taken me a
while to get in a position to actually do stuff.

I'm thinking of going ahead and getting a second washing machine which
will
stand alongside the existing one. I can sort out the water supply by
getting
a Y Piece (Screwfix) so that's not a problem. But I can't find the
equivalent for the drainage pipe. I can just about fit one pipe into my
existing stand so obviously two isn't going to go, is there something
available which can connect two drain pipes together into a third single
pipe?

I don't intend to drain the two machines at the same time so the capacity
need not be greater.

Cheers

I've done this for a washing machine and dishwasher, where getting another
waste pipe under the floor was going to be a real PITA. I used a normal w/m
trap and vertical pipe, cut the upstand close to the trap, and fitted a
swept tee into the vertical pipe, and an elbow to turn the result upwards.
Another vertical piece of pipe provides two inlets to one trap. The whole
thing takes up about 300mm width of wall with the various fittings.

We do not make any particular effort to ensure that both machines do not
pump simultaneously, and have not so far had any problems with overflowing.
This will depend on the particular flow rates of your machines, of course.

Make sure the vertical pipes are tall enough to give some immediate fall,
given that one is now fitted to an elbow above the trap.

Use plastic compression fittings, unless you are sure that the pipes
involved are glueable plastic, and the right size for solvent fittings.

Clip the upstands firmly, as the whole assembly will be a bit wobbly if you
don't.

Best of luck,
