    Toilet Drain
    Can two toilets that are on opposite sides of a common wall, use the same sewer drain
    Down through the slab foundation?

    Thanks

    Hey Carroll99:

    They sure can... ;) In fact, you can be sure of it.

    Can you tell us why you ask?

    Thanks...

    Mark, Thanks for the reply
    We are remodeling the master bedroom and the plan we like has the master bath located on the opposite side of the MBR from its present location. The toilet, shower and lavatories will be on a wall that has the hall bath on the other side of the wall. We can locate the toilet in the master bath so it is on the opposite side on the wall and in-line with the toilet in the hall bath. I was concerned that the plumbing code might require each toilet to have its own separate sewer drain through the slab. We live in Texas.

    Thanks Carroll

    Carroll, all those drains eventually come together in every house. You are just joining them early on, its allowed by code but you need to use the rights drain parts. I don't do rough in but Speedball1 and Massplumber do it all the time. Will you be pulling a permit, some towns do not allow this as a DIY project.

    Carroll, in Texas you can do your own plumbing work if you are the home owner and also the person that lives in the house but they reqauire you to get a master plumber to sign off on the work that it is done in an approved manner.

    Now all states are the same so you would want to check before you do too much.

    Hey Carroll99...

    Like Bob said, if you need some help designing waste/vent system let us know... glad to help! Bob also nailed it when he said a permit was needed here.

    And as Letmetellu suggested, check local codes in your area as codes differ from town to town and you may not be able to do this without enlisting the help of a licensed plumber!

    Let us know more...

    This is what it looks like under slab: it is double "Crossed San T" . Each horizontal outlet than extends via 90 ell extension to each toilet, terminating with Closet Ring.
