    Hi, I have recently removed the broken dishwasher we inherited with our new house. The waste pipe for the dishwasher was connected to the same waste pipe for the washing machine. Now the dishwasher and its waste pipe have been removed it has left a open gap (see picture). Due to the waste pipe for the washing machine being inserted above I need to block off the gap below. What is the best (and quickest) way of doing this? Can i get some sort of a plug/stopper to put in it?

    If it was me, I’d cut the vertical pipe just below the dishwasher connector, then, cut off the connector, and get a 40mm straight push fit connector from B&Q or similar and put the pipe back in.
    The vertical height will only be about two inches lower and should not make any difference washing machine waste.

    A washing machine/dishwasher waste is supposed to have a trap. If it has a trap then yes you can do what is mentioned above. If not fit a washing machine standpipe but as shauncorbs said a couple more pics would be good.

    It will still fit. They are designed to.

    A compression waste coupling can usually be made to fit but King of Pipes has the best solution, especially if the W/M waste doesn't already have a trap.
