Great product .. This product glues to the base of the toilet (the horn) and ensures a long term, leak free seal. All toilets should use these. I'll never install another toilet with a wax seal. If you have chronic "pee" smell in the bathroom you probably have a leak of the wax seal. The was seal is the weakest link the whole waste plumbing system and most likely to form a leak. It depends on beeswax for heaven's sake! This is what the Fernco Waxless replaces and reduces you chance of a future leak. Don't be fooled by the Fluidmaster waxless seals. They rely on a foam pad which in my opinion doesn't seal near as well as the Fernco. (Fluidmaster seals by compression with a gasket not a glued on connection) http://www.amazon.com/Fluidmaster-7500P8-Wax-Free-Bowl-Gasket/dp/B000BQUG7U/ref=sr_1_1?ie=UTF8&s=hi&qid=1301842760&sr=1-1 (Fluidmasters are at home depot but i did not find the Fernco there) I just installed 4 new Eco Drake toilets in my house and a few pointers when using these Fernco Waxless Seals.. If you have had the toilet seal leaking for a while examine the floor around the flange carefully to ensure there is no rot of the subfloor. If there is rot this should be repaired.. [...] There are three sizes of Fernco waxless seals. Choose the correct size waxless seal based on the flange and the pipe and how the flange is glued to the pipe. once the toiet is off examine the flange and the pipe that the flange is inserted on to determine which of the three sizes of Fernco you will need. http://www.amazon.com/Fernco-Inc-FTS-3-3-Inch-Toilet/dp/B000BQUJEA/ref=cm_cr_pr_pb_t (most common size for 3 inch pipe with flange gled to outside of pipe) http://www.amazon.com/Fernco-Inc-FTS-4-4-Inch-Toilet/dp/B000BVMZUG/ref=pd_bxgy_hi_text_b (for 4 inch pipes with flange glued to outside of pipe) http://www.amazon.com/Fernco-FTS-4CF-3-Inch-4-Inch-Toilet/dp/B000X1063C/ref=pd_bxgy_hi_text_c (for 4 inch pipes with flanged gled to inside of pipe, more commonly seen in basement toilets where the floor is cement) There are generally two sizes of pipe. 3 inch is most common 4 inch less common. You know what size of pipe you have to select the right Fernco . The flanges are also two different types. The flange can be glued on the outside of the pipe or the inside of the pipe. (Most commonly the flange is glued to the outside of the pipe.) Examine the flange carefully. This Fernco product is more forgiving when there is not an extension used and you may get by skipping this step. If you have had remodeling of the bathroom floor, the flange may be below the level of the finished floor. Toilets are designed to have the flange on top of the finished floor. If yours is below the finished floor, put and extender on the flange to bring it to the proper height. http://www.amazon.com/PVC-Closet-Flange-Spacer-Ring/dp/B000KKON1M These are attached to the existing flange using silicone caulk and stainless screws to fix to the subfloor. Sometimes you may have to add two or more of the spacers to bring the level to above the finished floor. I prefer size 10 X 1 1/2 or two inch stainless steel oval head screws placed through the flanges and secured into the subfloor. Sometimes you have to drill through the existing flange to be able to place the screws into the subfloor as the holes don't always line up. When installing, the Ferncos work best on a new toilet with NO wax on the horn of the toilet. They can be used on old toilets but ALL THE WAX needs to be removed. I used gas after scrapping all the wax off . Be careful when using these strong solvents and always use then outdoors. To insure the fernco bonds to the horn of the toilet, I used a hair dryer to slightly warm the toilet base to enhance the adhesive bonding. Seat the toilet using your weight to push the Fernco waxless into the pipe. Lubricate the flange and the Fernco with dish soap. Then, attach the toilet to the flange using brass toilet bolts, Johnny bolts, or glass filled nylon bolts. http://www.amazon.com/Toilet-Bolts-Open-Cap-Nuts/dp/B000L87RN4/ref=sr_1_58?s=hi&ie=UTF8&qid=1301844139&sr=1-58 Secure the toilet bowel to the floor and tight the toilet bolts. if there is rocking of the toilet from and uneven fit, stablize the rocking using small plastic shims as necessary (or pennies or lead shims) http://www.amazon.com/WM-Harvey-091816-Toilet-Shims/dp/B000H5OWE8/ref=sr_1_fkmr1_1?ie=UTF8&qid=1301844691&sr=1-1-fkmr1 If the toilet still wobbles slightly, secure it further using caulk. I like poly seam seal with just a small bead (you may have to remove it someday) leaving no caulk on the back of the toilet so that any water can escape should there be a leak for heaven's sake. (don't use silicone caulk! it seals well but is near impossible to remove when changing toilets.) Another alternative is to use plaster of paris rolled up in a "snake placed under the edge of the toilet bowl. Plumber's putty can also be used but it is kinda oily and tends to collect dirt. If the toilet was wobbly, don't sit on the toilet until the caulk dries to ensure the caulk hardens and gains strength.(usually overnite) [...]
