Since we moved into our newish house we have a problem with the washing machine waste slightly overflowing the standpipe.
The waste comes out of the back of the machine then loops up and over (with a U shaped holder) and into a standpipe (approx. 1m high, 50mm diameter). There doesn't appear to be any kind of a blockage and it only leaks a small amount of water each time (but enough to be messy/annoying).
Do you think the w/m could be pumping the water out too fast for the drain?
Would it help if we changed the standpipe to a bigger diameter?
The standpipe is approx. 700mm from the floor to the top.
The washing machine waste has to come through the wall and into a cupboard adjacent. It looks like the standpipe connects directly into the Svp through a floor socket ( hopefully if i have pasted this correctly you will se a photo!!).
