    Here's the situation. I pulled my old tub out and discovered that drain system looks like this:

    [​IMG]

    1 1/2 inch brass slip joint style connections.

    So I pulled off the the T joint and now I'm left with just a brass slip-joint style end sticking out of the slab.

    What I'm installing as a replacement for the tub is a fiberglass shower base with the drain located in the middle. The thing to note is that I can't (i.e. don't want to) relocate the drain, so underneath the shower base I'll have to run horizontally to span the distance.

    Here's my questions. I was down at the hardware store looking around and it seems brass slip joint connections have sort of gone out of style, because I couldn't find any. All I could find were the black plastic equivalent (ABS? which I suspect is the standard now). Will I be okay attaching an ABS elbow to a brass end?

    Next question is about achieving the recommended slope (1/4" per foot) for that couple of feet that my drain will be running horizontally. How to you achieve a slope between two 90 degree elbows? Is there that much give in the joints? I know it's only a 1/2 inch of slope, but wouldn't anything other than a dead straight connection compromise the integrity of the joint?

    Also, can these slip joints be trusted for something like this? My mind would be much more at ease with say, a glue or solder joint. I fear the day one of those nuts starts to come loose and my only way of accessing it is to pull up the shower base.

    So yeah. Hopefully that give you an idea of the situation. I'd appreciate any guidance you can give, or specific answers. Thanks!

    Sewer bends are usually 88degree or 85degree bend to allow for fall. Even though they still get called 90 bends.

    As far as type of pipe etc, kind of different to what is used here in Australia. I myself would adapt the brass to PVC and glue the shit together, but yeah..

    Use PVC "white' or ABS "Black", pvc is better but its availibility may be regional. Make sure you use solvent and glue, to glue it together. Make sure you dont use cleaner. you can get the pitch out of the joint. Adapt the PVC to brass using a rubber plumbing coupler, its a rubber coupling with two stainless pipe clamps.

    good luck.
