FERNCO FTS-4CF 3-1/2IN, 4CF, Toilet Seal, Wax Free

Worked like a charm! Be sure to clean thoroughly around the toilet opening so it adheres properly to the bowl. Press firmly around the glued area several times to ensure a secure, tight fit.

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.

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.

Damn construction company set my toilet flange tipped over and too deep (1/4” one side, 1/2” on the other). This product fixed all of those problems. It has a very sticky adhesive to attach to the toilet horn and is made of a durable rubber-like material. I believe this will far outlast those foam wax-free pieces of junk.

For this to work properly, your mating sewer drain pipe for the toilet should be a matched sized PVC to the wax free seal and in good condition (not pitted or grooved). If it is not a smooth PVC mating surface or your trying to use this on a rough surface cast pipe, it is not going to work. If installed properly, these things last at least 10 times longer than the wax seals. I have installed several of these over the last 5 years and none have leaked so far. Tip: On one cast toilet floor drain pipe I installed one of these on, I honed out the rough surface just enough to fit a mating 5 inch long PVC pipe into it. Before inserting the PVC pipe, I heavily siliconed the mating surface of the cast pipe so the silicone would seal the PVC to the casting. I let it sit for 24 hours and then installed the toilet with the new wax free seal. With the old wax seal, I always had a problem with this toilet blowing the seal whenever the sewer line back up for any reason. Since installing the wax free seal, it has never blown the seal or leaked whenever the sewer has backed up. This was well worth the extra effort to install.

Much better replacement for the wax rings. Good strong seal against the toilet base. Be sure to measure the inside diameter of the drain pipe for proper fit. Use a little dish soap and this seal will slide in and properly seal.

Wrong size, returned. Probably works for you though

GOODD

Not installed yet but it looks perfect.

Excellent product.
