40mm drain to Square gutter downpipe?

[philipp]

Looking for a bit of help.
I want to move the washing machine into an integral garage to free up some space in the kitchen. The garage already has mains and a cold water supply so i just need to sort out the drainage. I'm thinking i can drill a 40mm waste pipe through the garage wall and hopefully connect it to this square gutter down pipe. What kind of connector/brace would i need? ie: 40mm round to square gutter down pipe? Looks like the gutter down pipe has some kind of shoe. Am i better off removing this and taking the 40mm waste pipe directly down and keep them separate?

First - Are you sure your water authority allow this? The square gutter down pipe is for rain water. The water from your washing machine is grey water. Many areas have two drainage systems, one for taking rain water away, untreated, then a second one for grey water/sewage, which needs to be treated.

It's illegal, to discharge grey water/sewage, in a rain water only system.

Follow the manholes to where your toilets drain, and where your rain water go - if they are definitely one and the same, you can do what you propose.
