I have read many different threads/posts about flange extenders and still am confused.
I am removing the vinyl floor in my bathroom and installing hardibacker plus tile over the existing plywood subfloor so I need to raise the flange about 5/8 to 3/4 in. or so.
My existing trap/flange is PVC.
One of the "U" slots where the "T" bolts go is broken
on the existing flange so that only one "wing" sits under the flange. The heads of one or two of the 4 screws that hold it to the plywood look corroded enough
that I can't make out the "X" anymore where the screwdriver should go. The screws themselves
might be fine.
The rest of the flange is in good shape and the subfloor
looks to be in very good condition.
Questions:
1. Am I supposed to remove the 4 screws to the flange and screw the flange extenders onto the flange all the way through to the subfloor? or do I somehow attempt to attach the extenders to the original flange? Or do I
attach the flange extenders all the way to the subfloor
through new holes in the old flange?
( I know to use silicone caulk or something between
the extender(s) and each other and the flange. )
2. Is the broken U slot going to be a problem? Do I need one of those repair plates? Do I need to be able to get the existing screws out to make it work?
( From other posts, it appears that if the extenders are anchored to the floor, it is permissible to use the "U" slots on the extenders )
3. Do I install flange extenders before or after I tile?
4. How closely around the flange and extenders do
I cut the hardibacker and tile (gap or no gap)?
5. Do I grout or caulk or nothing in the gap between the flange extender and tile and hardibacker?
I know this is a long list. Any help with any of the pieces would be greatly appreciated.
