Wastes for sink, dishwasher and washing machine

[eddieboo]

I can't believe that this question has not been asked before, but I have searched many a forum and cannot find it.

I am having trouble designing a waste solution for kitchen sink, DW & WM. I will explain my situation.

The waste stack is on the left hand wall of my kitchen. One metre away from the wall (right) will be the sink. To the right of the sink will be the dishwasher and then comes the washing machine. ie, both appliances are after the sink.

I know that I can get an undersink waste with two appliance spigot connections, but cannot believe that the waste pipe from the WM will reach around the DW and then into the cabinet to connect to the trap whilst still having enough slack to pull the machine out from the wall. I can see that if the two appliances were either side of the sink, this would not be an issue, but would prefer not to have it this way.

So, I picture the waste pipe coming from the soil stack and meeting the trap under the sink, then maybe continuing the pipe and putting in two tee pieces, behind each appliance, with waste nozzles coming out of the tees, but then how would I terminate the pipe after the two tee pieces?

If I have to give-in and change my intended arrangement, I will, but it would be great if someone could think of something!

Why do you need a Tee behind the washing machine? Can't you use an elbow so there is no open end to terminate?

If the wm drain hose is too short, you can get extensions.

Or you could extend the sink waste pipe towards the machines, with a running trap fitted to this pipe. Then put two 40mm pieces of vertical pipes as upstands for the machine waste hoses.

Attach waste from nearest appliance to spigot on sink waste, (providing this gives you enough slack on the hose). Take your 40mm waste from stack, connect sink waste on a Tee, then continue behind 1st appliance and fit a standpipe on the end to accept 2nd appliance waste.
