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
