trying to install a washing machine. ran a t piece off the cold and into washing machine inlet. waste pipe from washine machine is connected into sink trap.
everything seemed fine, no leaking joints, however, when the washing machine drains, the water is filling back up through the sink. this also causes some leakage - it seems that the sink waste pipe doesn't like all this water flowing back up it.
anyone any suggestions as to what could be causing the water not to drain away correctly?
