How do I install a suitable standpipe?

you drill a 1/3/4" hole through your wall at the rear of the washing machine( maybe easier to smack out half a brick) pass the pipe through the wall fix a 90 degree elbow on the outside, in to this run some more waste to your drain.inside the house fix another 90 degree elbow, at this point may need to SHORTEN the pipe that passes through the wall so that the elbows fit CLOSE to the wall on BOTH sides insert another piece of waste pipe and cut off just under the height of the washer unless you have a manual giving A MAX HEIGHT,MAKE GOOD THE DAMAGE TO THE WALL fill hole up with mortar BOTH SIDES AROUND THE PIPE and secure with pipe brackets
(IGNORE THE STAND PIPE METHOD FITTING ABOVE IF YOU LIVE IN A HIGH RISE FLAT) CONNECT DRAIN HOSE TO THE U BEND ON THE SINK BUT RAISE THE PIPE BETWEEN THE SINK U BEND AND MACHINE TO PREVENT BACK SIPHONING.
