    Usual story. Circa 1960 house with drum traps for tubs. Have found articles and videos on replacement with p-trap but unable to find anything relating to when there is a third connection going to a vent.
    Also, this appears to be lead. Does that complicate things ?

    Thank you.

    The vent will transition to a galvanized pipe in the wall
    you will need to cut the sheet rock behind the tub wall and remove the lead pipe
    tie onto the galvanized pipe
    cut the wall in the room behind the tub.

    That looks like the setup. How do I tie the vent pipe back into the P-trap after I take the drum out ?

    remove the drum trap and the lead pipe
    back to what ever it ties into, that is not pictured
    tie onto that with a fernco proflex band
    and repipe it with pvc

    drum4.jpeg drum5.jpeg drum6.jpeg drum7.jpeg drum8.jpeg Can't see it very well but, it looks like the vent pipe goes up about a foot before joining a different pipe.
    The drain runs to a bigger lead looking pipe, that I assume is under the toilet, which attaches to an , I assume, cast iron main outlet. Is all of the dark grey lead ?

    One problem is that the tub wall backs to another bathroom with a full vanity in the way .

    I am not commenting on advice but whomever did that job looks like he earned his money. One of the finest lead jobs I have ever seen

    I find it hard to believe they were still installing lead drum traps in new homes in 1960.

    I'm understanding that all of the lead needs to be removed and replaced with PVC ? I can't just remove the trap itself and replace with a P-trap ?

    No you have to remove unless you can wipe a lead joint

    There isn't some kind of PVC to lead coupler ? The pipe leading into the long drain pipe at a Y is also coming from a second tub with a drum trap.

    Hmm. Much bigger project then I anticipated. It looks like the pipe directly under the toilet would have to be replaced also.

    Lead bends used for toilets are different there are ways that you can reuse them or attach a coupling on to them

    After pondering this I think I'll call a pro on this one :) Thank you for your advice.
