I have a soil pipe coming down from the upstairs bathroom. I want to plumb the washing machine waste into said pipe downstairs. Can this be done?
I understand a special type of trap would be needed to stop blow back - what exactly do I need?

I think you can do it with a strap on boss and a washing machine trap for starters-

Chez,
both your links go to the washing machine trap.
The hidden url is the same in both.

Think this is the one you meant.

Yes a strap on boss and washing machine standpipe and P trap should do the job, but keep it up about 400mm from the bend.

Thanks for the info on the boss - in the screwfix trolley already!

SWMBO also wants to original toilet reinstating (we've smashed an old downstairs loo into the old coal shed to make a bigger internal room), so I want to ensure we don't have issues when this happens.

Would I need some kind of trap to stop the toilet sucking the trap dry and thus letting the smells up the washing machine waste pipe?

You also need a 40mm boss adapter to be able to fit the 40mm pipe to the boss.

Boss adapter

Infact it'll work out cheaper if you go to B&Q and get a standard 40mm strap on boss

Marley Strap On Boss (Dia) 110mm x (L) 40mm - available in Black or Grey

Not all strap-on bosses require an adapter, some are O ring to the right size.

Thanks guys for the info on the Strap-on boss. Will go to B&Q as recommended.

What about the bottle trap?

No, get the proper washing machine trap and standpipe, it's sold as a kit.
