Wax Free Toilet Seal for 4 in. Drain Pipe is rated 4.8 out of 5 by 11.

Once you install one by properly following the instructions, you will never go back to using a wax seal again. Should have been invented a long long time ago.

Rated 5 out of 5 by from success story I just reinstalled my basement toilet using the Fernco 4" Wax Free seal. My flange is not level with the concrete floor. My old wax ring deteriorated over time and the toilet was leaking. Because of the unevenness of the floor I decided to go a different route. I cleaned and sanded the toilet horn and surrounding area to remove all traces of wax. Wiped down with alcohol and attached the seal. I centered the toilet over the flange lowered it and felt it drop into place. Shimmed, leveled and bolted to the floor I flushed it numerous times. Success. I will now grout under the edges to help support the toilet. I highly recommend this product...

Rated 5 out of 5 by from Best waxless toilet seal there is These are the best waxless toilet seals you can get. The toilet can be installed and removed over and over again without changing the seal, they never leak (if the directions are followed) and they can accommodate extreme variations in the height of the waste pipe flange. I won't ever use a wax seal again. The only thing I wish is that Home Depot carried them in stock in my local store. I had to order them. Ship-to-store is free but there is a waiting period involved. Also, if you haven't used one of these before, you have to know the I.D. of your waste pipe because this seal spigots into the pipe. Fernco makes three sizes to fit various pipe sizes. If you don't know what you have, you will need to pull the toilet and measure the pipe. That's the problem with having to wait to get the seal. Either you have to put the toilet back in with another seal while you wait, or not use that toilet until the seal arrives. Alternately, you can order all three sizes in advance and return the ones you don't want to Home Depot. Finally, if you are replacing a wax seal, be sure to thoroughly clean the wax off of the bottom of the toilet with rubbing alcohol as the instructions tell you to do. This seal must adhere to the bottom of the toilet. But the adhesive really sticks to a clean toilet! I replaced a toilet that had one of these seals with a new toilet and tried to get the Fernco seal off of the old toilet. I was nearly impossible. You cannot get it off and reuse the seal on a different toilet. But I could see that the seal was never going to leak.

Rated 5 out of 5 by from Product review A great idea! No wax ring. No wax mess. Wax free toilet seal is easy to install (check out you tube installation instructions). Make sure you clean the bottom of the toilet in order for the ring to adhere properly. I will use this on my future toilet projects.

Rated 5 out of 5 by from Troublefree toilet seal - makes installation much easier I've been doing home maintenance for over 25 years and until recently, I was not a huge fan of installing toilets. Previously, I used wax rings, which work well most of the time, but once in a while, the toilet needs to be moved a little and the wax seal fails. If you're lucky, the wax ring fails while you're there doing the installation. If you're not lucky, your tenant calls you to let you know that there is leaking water out of the toilet - usually comes with a pretty stinky mess. With this product, you will not have a bad seal. The top of the seal has a sticky glue, which fits on the bottom of the toilet. After the seal is installed, you just place the toilet over the drain and push it down to seat the seal. Screw the bolts down (ones to hold the toilet to the flange) and install the water supply line. Check for leaks and caulk the toilet to the floor. That's it! I will never buy a wax ring again!

Rated 5 out of 5 by from Fixed our leaky rear ejection toilet We have a rear ejection flush toilet (wall mount) that was installed by a licensed plumber during a remodel project. The toilet leaked from the start and the plumber returned and installed two wax seals to solve the problem. The leak stopped for 9 months and then appeared again. After researching what seal is appropiate for rear ejection toilets, this seal was recommended. This Fernco wax free seal installed easy and stopped our leaky toilet. I would highly recommend this seal.
