I am having an upstairs tub pulled to get at water damaged subflooring. O'Mike and some have already given me quite a bit of help on a flooring thread but I thought to ask some tub specific questions here on plumbing.
Some background is it is 22 year old Sout Cali tract construction. Existing tub is a pretty standard 5' x 30" porcelain over steel set into the alcove at the end of the bathroom, which has 16" oc 10" joists perpendicular to the tub. Sub Floor is OSB t&g. No flexing of the existing tub has ever been noted. Feed piping is copper and waste lines are ABS. Tiles are all common ones stocked at Home Depot so there is no concern with matching old and new. Floated on 3/4" thick concrete. Water damage is so far assumed to be from water spashed onto floor that was poorly caulked (actually grouted).
I have tried to gather some info here and elsewhere in the internet and I think I have a pretty good idea of the process. I plan on doing this myself but with some help and possible just hiring a contractor to do it all.
My first thought was to pull and reinstall the original tub. Two contractors said that can be done but a third is concderned that it will be damaged in the process and that I be prepared for a new one. He likes the BootZCast. Does this suggest that he is unsure of his skills or does it sound like he simply is being honest and wants me to be prepared for the additional cost of a new tub?
Should the BootZ be bedded in mortar, even though it has what appears to be a styrofoam levelling pad? I read the current thread on the same question but concerns a resin tub. BootZ warranty is voided if the self leveling pad is removed.
How is the overflow and waste connected to the drain? Is it done via the hole in the subfloor, by reaching down between the studs, or should I expect to have to cut an access hole in the back wall (on the other side of which is a closet)? Alternatively, can it be connected to the drain before you set the tub in place and then you connect the overflow and shoe?
Should the valve be replaced? If we get the tub out and there are no signs of the studs having had water running down from the valve, should it be replaced, now? As is, the plan is not to remove tiles up to the level of the valve. My thinking is that if the valve later goes bad, we won't know until we see water damage. Contra argument is I may be opening another can of worms.
Thanks for any advice you can give.
