Review: Best fix out there - This was the last thing I tried to seal a toilet that must have been a second sale item. The toilet base wasn't level and I tried two different wax seal with poor results. This one fixed it! It was easy to install fit tightly into the drain line and no more leaking. Makes a one man job a lot easier.
Review: It works - It works perfectly

### ⭐⭐⭐⭐⭐ This is a fantastic product.
*by J***P on December 9, 2012*

I was a bit skeptical at first - but after speaking with a local plumber I decided I would go ahead and try it. Our bathroom closet had a sewer smell that would come and go. We washed out the vent pipes on the roof and the next thing to try was to pull the toilet and replace the wax ring. Come to find out, the wax ring failed and was allowing sewer gases to enter the home - rather than have to worry about a wax ring and after the positive feedback from a plumber I installed this product. The adhesion of the seal to the porcelain is quite good - if you had a wax ring before I would certainly recommend scraping off the wax and using a fairly stiff brush attempt to scrub and remove the remaining wax remnants. Only apply the seal once the wax is removed from the horn and the surrounding area and after the porcelain is completely dry (we used a hair dryer to speed things up). Upon installation I certainly "felt the seal" - another tip I would also recommend using dish soap to help the seal's ribs go into the PVC. 2 weeks later, no smells and no leaks.
