    Ok reread Frodo and MrDavids old posts. Sounds like I can buy a p-Trap with a rotatable weir. Is that rotation counted against the 135 degree limit before being required to install a cleanout?

    Still don't understand how I'd be able to use a sanitary tee to vent.

    no, the 135 degrees does not include the p trap

    Reread some of frodos and MrDavids posts. A trap with a rotating weir maybe the solution. I'll check my local plumbing shop.

    diagram showing drain distance from the main stack. Is it possible to implement the santee solution?

    Couple questions

    1. How close to the ptrap can the sanitary tee be?

    2. Is the 90 degree turn of the sanitary tee counted against the 135 degree limitation?

    yes, the tee is an offset

    you are allowed 6' from the tee to the weir

    using 2'' pipe

    So if I put a 90 on the bottom of the tee to bounce back to that toilet, I've turned 180 degrees which is greater than the 135 limit.

    Look at my pictures . pretty close is okay

    After the vent connection to the santee, the drain is no longer the trap arm.
    So the 5' max of trap arm is to the vent, not total drain length.

    They wye is backwards.
    Frodo drawing is what it should be but the vent is going the other way.

    Can I use a sanitary tee instead of a tapped santee? Looking at the Charlotte manual, the sweeps seem similar.

    Ok Here's my new plan for the drains. Does this work? There will be 90s at the bottom of the tees.

    Thanks

    2'' trap arm max length is 5' upc code
    and 6'' ipc code

    depends on where you live

    Can I cut off a 1/2" from the bottom of the sanitary tee? I already took an inch off the 90 that attached to the bottom of the santee.
