Connecting up Washing Machine, Dish Washer and Boiler Waste All aspects of plumbing questions and answers, help, tips and information

[somser]

Hi,

We're putting a new kitchen in and I need to connect waste pipes for a washing machine, dishwasher, and boiler to the sink waste pipes.

Any advice for what the neatest way of doing this would be?

Would I need two standpipes with P-traps or could I get away with using one?

Thanks!

If you have the room for 2, that's the better option.

The condensate pipe needs to be connected downstream of the trap, as the condensate can become the flue, if there was an issue with the boiler, if fitted upstream the fumes could enter your home
