    We are needing a toilet in the basement and we have the stack available in the laundry room. Can we use the rear discharge toilet and go into this??

    Are you talking about a pump up toilet system like a Liberty or Sani-flow? Its recommended to tie into a 3 or 4 in line which
    you have. They also need to be vented.

    Hi Tom,

    No, I am talking about a rear discharge toilet and have it tied into this stack.

    Have you looked into a rear discharge toilet. They have to go into a carriage that ties into the main line. It could
    probably be done but that clean out wye is in the way and would have to be rearranged. A pump up toilet system would be ideal in your situation.

    yes you can buy a floor mount/ rear discharge terlet, that does not require an expensive carrier

    but...the terlet itself is aroud $300.00....and thats a cheap one

    All of this will have to be removed and reconfigured

    or a platform built.

    no.
    well....yes you can. but the flange will not be 4'' off the floor

    what you have to do is easy,
    shorten the 2 pipes at the top the same as the take out on the tee
    cut the bottom 1 1/2'' off the floor

    set that section aside

    install the tee

    clue the removed section into the top of the tee

    reconnect the pipes using 1 --each proflex couplings
    model numbers. 4''--3000 43
    2''---3000 22

    pop the top on a cold beer.

    Sorry, but how high does the toilet flange have to be above the floor to have enough room for a 3" bend and then connect up with the san. tee centerline, which looks like would be a minimum of 4 1/4" above the floor?

    Not sure what that 4" dimension represents.

    I read that hooked up like this , when a terlet upstairs flushed, it will suck the water out of the downstairs one.

    no it will not

    for that to happen the whole system would have to be no-vented
    and the terlet upstairs would cause a suction
    the main stack. is vented via the washing machine vent, it will not back siphon

    Hmmmm...Would it be reasonable to assume it won't be that existing concrete block wall?
    Does OP plan on building a new wall for the purpose of using a wall mounted toilet? I suppose that's obvious. I retract the question.

    he really does not need a wall, the terlet bolts to the floor
    so their is no strain on the plumbing.
    for sanitary reasons i would build a wall
