My father-in-law wants to add a toilet in his laundry room and since I have installed sinks and faucets for him, he thought I might be able to answer his question about accomplishing this new task... but I can not...

He wants to know if he can add a toilet into the laundry room and he wants to use the same drain as the washing machine.

First question. Is this allowed? :confused:

Second question. If it is allowed, is a trap required in order to prevent any backups from the toilet into the washing machine?

Can you point me to some instructions on what is recommended when adding a toilet to a washer drain?

Thanks so much.

Not one single answer?? Bummer. Did I ask the question incorrectly?
