Joining 2 toilets together.

Jackinbox99

I am planning to build an on-suite bathroom in my main bedroom. This will involve fitting a toilet against a stud wall. The other side of the stud wall is the main bathroom for the house and the main toilet for the house is actually sitting the other side of this stud wall.

My theory is, i could just feed the waste pipe from the new on suite toilet, straight through the stud wall, fit a Y piece between the current bathroom toilet & the soil pipe, then connect the new toilet to the Y piece. So 2 toilets will connect to the same soil pipe.

Problem is, I cant seem to find anywhere which does a Y connector for toilets. Any ideas?

Or does my plan have any obvious problems which ive missed?

Thanks
Jack.

I don't know anything about the regulations, but I'd be surprised if you can do what you're saying. I'd expect the new toilet will require its own branch from the main soil stack, and can't be simply tee-d into an existing branch.

System

a back to back y connection would likely mean that when one toilet was flushed the water would be pulled from the trap on the other, so probably not a great idea! it should have it's own connection to the soil stack

Exactly and the nasty niffs promptly enter the building. Its for the same reason that a bath, basin and shower should have separate waste pipes.

Thanks, i was just chatting with someone else and he mentioned something about building regulations saying both toilets have to go into the stack seperately and be a certain distance appart. Which explains why I cant get a Y piece like I thought. Makes my en-suite plan more difficult as Id have to now some how take a feed from the stack below the current one to give it the right angle, then feed that through into the ensuite..... hmmm...
