Kitchen Sink Waste

[reggie76]

Hi,
I am planned to move my sink to the other side of the kitchen, this will mean either a run of about 4 metres to the original drain, or running through into the bathroom next door and connecting into the bath waste, this would been a run of about 2.5 metres, but would involve a verticle drop of 50cm, is this acceptable??, if so, what size pipe should I be looking to use, cheers

you should not have two appliances sharing the same waste, its a bugger to clear if it blocks up

how much drop do you have on the 4 meter run
