replaced the toilet ring on the master bath commode. The ring was rotted, pulled up and was allowing a very slow leak that eventually caused some staining in the kitchen ceiling.
but it took 3 attempts to find the solution that actually worked, because the builders left the pipe short, and compensated by opening the hole on the short side.
assholes. I ended cutting back a little tile, working in a two-piece ring by inserting and sliding the half-ring around. At first I tried a spacer to bring the flange up, but i wasn't getting any grab from the screws on the wide side of the hole - they were just hitting soft plywood edge. figured that out when I went to put the tank on and it rocked up on that side.
assholes. I had to wedge a screw down between the hole and the pipe on the short side to center the pipe in the hole, screw down a half-ring, drive the screw in to the subfloor gap, work the other half-ring in, then pry the half-ring and pipe over to the other half and screw it down.
assholes.
but I got it done. fuck plumbing.
