    Default How to raise Tub Waste Shoe in New Installation

    Hi,

    I am replacing a tub and its fixtures. The drain kit assembly is older than me (50+ years) and I have been planning to replace it, even though it has no leaks.

    The replacement unit I purchased (see http://www.moen.com/shared/docs/prod...ns/90410sp.pdf or http://www.moen.com/shared/docs/inst...ts/ins1680.pdf) has a 3" pipe below the waste shoe (please scroll to the bottom of http://www.moen.com/shared/docs/prod...ns/90410sp.pdf to see the 3" pipe). The problem is that in my current assembly that piece is almost 4" long. If I sweat the current set up and install the new part, the waste show will be below the floor.

    What options are there? The local Home Improvement center did not seem to have a solution, other than suggesting I keep the existing set up and replace the waste shoe and trip assembly with the one from the new kit... Definitely would be easier. But, I am not sure if that's a good idea.

    What do you suggest?

    That piece screws in, and you have to remove it and apply pipe joint compound to its thread before you install it, or it will leak. THEREFORE, all you have to do is purchase a 1 1/2" x 6" or 12" threaded tube and cut it to size before affixing it to your drain's tee.

    That's good to hear. I tried, but seems like the piece in the picture below is tightly attached. Could htey have used pipe joint compound in the factory? How can one remove it?

    They must have made that for the "do it yourself" trade, because I have NEVER had one preinstalled that tightly. If the factory assembled it, then they probably used "litharge and glycerine", if so, you have to heat it up to unscrew the piece.
