is there any point in having a hot water pipe to the washing machine any
more? I gather they dont use that much water nowadays anyway (and can heat
the water if necessary), so by the time the water has got from the combi to
the washing machine it might already have enough water in it anyway. I
remember the machine coming with a y-piece but I just connected the two
pipes as we had them already plumbed in. Would I be better off sticking in
the Y-piece to connect cold water to both inlets? (I guess this will also
have a positive effect on someone using the shower while the washing machine
is on?)

cheers
