apologies if this already answered. I did look. I have an old cast iron flange and perhaps some floor flex. Considering the Danco although the fluid master looks better for my application. The flange is not quite level and goes from about 1/8 below finished floor in front to about 1/4 below in the back. The finished floor itself is pretty darn level. All the Danco vids show use on ABS or PVC. Same with the other products.
Will any of those rubber seals work on old rusty cast iron? I can clean, scrape, wire brush, sand, whatever.. Still gonna be a pitted surface. Yes I know there is a wax piece in the Danco.
One option I have been considering is using a plastic spacer, seal it with silicon and bolt it tight so I have a clean smooth surface for the gasket. Will the silicon stick to the rusty surface?
Question.. On the Danco.. remove the blue? The black plastic on the bottom? It really looks like it would be too high to get the toilet to sit.
The Fluidmaster better than wax actually looks better to me, perhaps with a spacer carefully attached and sealed to the old cast iron?
I am asking because I anticipate and perhaps can feel some floor flex. Its an old house and destined to be a rental that I don't want to visit when done.. Learning a new trick would not be bad either. I have installed a few toilets, always going to the wax ring, often (more often than not) stacking. A neater method would be nice as I always have a mess to clean. Usually I take 2 sets of rings, stab the toilet and if it doesn't feel right, pull it up, change out the wax and try again..
I tried one of the twist-n-set varieties on another property, also CI, but getting a seal against the rust stuff seemed impossible and in fact lifting the toilet lifted out the twist-n-set from inside the pipe.
Ok thanks for the input. I am expecting trial and error here as is usual with something new to me.
I am expecting its either stacked wax or the Danco without the blue piece if I can get it to compress. Too bad their instructions are so weak..
