Hi all
Hope everyone is staying safe in these bizarre times! I was hoping to get some advice from the experts on waste pipes for a washing machine. I'm not a plumber, but I think I'm reasonably able when it comes to DIY.
I'd like to move my washing machine from the kitchen into a hall cupboard in my first floor flat. My current plan is to install a standpipe on the left wall of the cupboard and run it through the stud wall at the back of the cupboard to join the vertical 40mm waste pipe from the ensuite sink (approx. 18 inches distance). I've crudely drawn this onto the photos.
I've had a look through the forums and came across this thread which describes a potential issue - if the sink is discharging at the same time as the washing machine would the water be likely to back up and overflow the standpipe? The other concern I had is that when waste is discharging from the sink could it create a suction effect and draw water from the standpipe trap?
Unfortunately I can't easily access the soil stack to add a separate waste for the washing machine, so it would need to connect to an existing pipe. I suppose an alternative solution might be to run the washing machine hose through the wall and connect it to an appliance trap directly under the sink - this is how it's connected in the kitchen and makes a bit of a racket when it's draining so ideally I'd avoid this if possible.
I hope this all makes sense - any advice would be greatly appreciated!
