The rubber gasketed model will work just fine. You have to secure the drain to the shower pan before setting it son any connection has to be made between a stationary pipe and a stationary drain. Some drains use a rubber seal that is "caulked" into place and they also seal properly.
: I'm a homeowner and trying to replace the upstairs shower (a plastic shower pan with tiled
: wall arrangement) with a 2 piece fiberglass unit. I'd rathern not have to cut away the downstairs
: stippled ceiling to get access to the floor drain plumbing from underneath the shower stall.
: (Reason: this gives much more work in repairing the opening, replacing the stipple, and then
: painting the whole ceiling there). But feel that I can prepare the plumbing from the top (access)
: by cutting away some plywood flooring, positioning the drain pipe correctly, and then replace the
: plywood flooring that was cut away. Then I can set the fiberglass unit in place. The question is
: this: does a floor shower drain fitting exist that allows me to connect to the drain pipe (2" PVC)
: from the top, without having to gain access from below, AND, is reliable agains leaks? (I'd like it
: to last at least 10 years not leaking, if possible). Please help me.
: I have purchased two styles, one is: a type made of PVC and of solvent weld connection
: to the drain pipe (seems to require access from below to glue the connections between it and
: the drain pipe). The other is a cast brass type with an elongated rubber ring seal that fits into
: the brass fitting and goes around and seals around the outside of the 2" PVC drain pipe.
: (It has a threaded ring that screws into the inside of the drain fitting and pushes down on the
: rubber ring so that it tightens against the outside of the 2" PVC down drain pipe. This system
: does not seem as watertight as the solvent weld variety). Is there a better system out there
: that I can do this job without cutting out the downstairs ceiling to gain access to the plumbing?
: Say, a fitting that has a more secure screw in type of arrangement that I can connect to the
: drain piping from the top, by, say, a screw-in motion? Please please help me. Thank you
: very much. I would also like advice on the cast brass drain fitting I described, please. Is it
: reliable, and would you use it in your home. Thank you very very much.
