The bolts in the bottom section of the drain don't usually seize-up unless it's a metal drain assembly. Is it?
It may be possible to break off the bolts and grind flat ... then drill for new bolts, but it's a lot of work and can cause problems if done incorrectly.
Hi Harry-Sorry for taking so long to respond. I have a new 3 piece drain. For lack of proper terms for the pieces, I'll refer to the "bottom" as the one that gets glued to the pipe that comes up from the ground, the "top" as the piece that has the drain cover screwed on to it and then gets screwed into the "middle piece" the piece with the weep holes.
I was able to remove the old top piece and middle piece. I am left with the bottom piece glued to the drain pipe proper. Two of the bolts on the middle piece broke off, the other two bolts turn but will not come out. When I look down into the drainage pipe, I can see where the bottom of the drain assembly is glued to the drainage pipe.
I think I can cut that junction with a Dremel tool and cutoff wheel by inserting the Dremel down into drain pipe. Will I have enough room surrounding the drain pipe to add a coupler and a small length of pipe and then the new drain fixture? IF I were to do this, the diameter of a cutoff wheel is not large enough to go completely thry the pipe without cutting at an angle. i.e. the inside part of the cut pipe would be a bit lower than the outside of the cut pipe. Once they are separated I could grind the top of the pipe so that it would be level all the way around.
Can I cut off the 2 remaining bolts of the old bottom piece (still glued to the pipe), use fine sandpaper to clean to top of that piece very good and just used PVC cement to cement the new piece onto the old piece and not actually cut the old piece from the drain pipe?
IF I were to call a professional to install the drain and install the shower pan and get the floor ready to the point of tilling, who do I call? A plumber? tile person? Cement of concrete person? Would once person handle the whole thing even though it may be outside their area of expertise? A general contractor?
Thanks for any insight!
