My code book will allow two water closets on a three inch horizontal branch. Why do you ask? Hope this helps and thank you for rating my answer. Tom

Tom gave you correct answer. If you are having more than 2 toilets than you will have to upgrade to 4".

Hi Guys...
In my area you can have up to and including 3 toilets on a horizontal drain line... ;) I am under the Massachusetts uniform state plumbing code.
What area are you from LRKM123..?
