I'm not a plumber. I have installed/replaced maybe 10 toilets so far in my life.
Not an expert by any means.
We had a laminate floor installed which left the flange about 1/3 inch below the top
of the laminate floor. Cast iron piping eliminated sliding the floor under the flange.
Bummed.
I took a heat-soften wax seal and smashed the wax all around the outside of the
cast iron flange so if there was a leak the water would come out on top of the new floor
hopefully so I would immediately see the leak. Then I used this new seal instead of a wax
seal. It cost about $10 vs ~$1-$3 for a wax seal. I was able to set the toilet to make sure
bolts and toilet were seated properly then removed it for adjustments. This was worth the
extra $7 to me a novice at this game!
I was very impressed at how easy it worked for me.
Sure wish I had the patent on this new product. Thanks guys for your input. If anyone has
any negatives I sure would like for you to share. Thanks~
