drain pipe for washer

[cmossom]

Hi all,

can anyone answer me this question?
I live in a mid terraced house and i want to put my washer under the stairs but confused on the right ways to plumb the drain pipe???
Should i just extend the washer pipe or plumb a drain and u bend in the crawlspace under the floor any help would be fab guys cheers

You dont want a long horizontal leg of waste hose from the machine. (Will collect crud and soon start to stink and/or block!) It needs to rise as close to machine as possible, to then discharge under gravity. If it is possible to run a 40mm waste pipe under the floor to a suitable drain then thats the method to employ. I'd fit a washing machine trap above the floor level, then run the waste from that under the floor.

Cheers for the advice.

The only grid that i have is in the back so i would have to go down under the floor board and then back up above the boards again to get to the grid.. but i worry that the smells from trapped water would start to smell.

Will have to see if i can run it along the back of the kick boards and cupboard instead.

thanks for the advice though

It will smell, and block too quite likely. Needs to use gravity, otherwise its a pump away job or a no can do job.
