I might add silicone to the bottom of this gasket, too, just to play it safe so no water leaks to the outside of the pipe.△The tire producer / manufacturer of the tires you are buying, and Canadian Tire is responsible for the recycling fee that is included in your invoice. The plumber supply guys said to use the silicone directly under the flange metal, thus it will sit on the very top of the rubber, double-ring gasket. I asked where to put the silicone sealant as the manufacture states to use, but instructions had no diagram or directions. This device comes with an interesting rubber, double-ring gasket that goes directly beneath the flange in the sink. NOTE: I had to stop at the plumber supply to get an answer, and I'm still uneasy. Putty at the gasket from the bottom side of the sink does not work.įor those looking for these hard-to-find Pop up drain assembly WITHOUT overflow, here's a link to Kingston Fauceture Pop up Drain assembly Without Overflow: And sure enough, after assembling, I cannot stop the leak at the nut. The new Moen faucet only comes with assemblies WITH overflow. The prior drain assembly has overflow holes in it, but there was never a leak. I have a vanity, cultured marble sink without an overflow. You may want to consider whether someone will be rinsing contacts in that sink when making your choice of drain assembly. And, no stopper (to hold water) is required. The codes only require a single bar across the middle of the drain so that nothing as big as the drain can go down it. If you want a vessel sink without an integral "overflow", then you should look into the different types of drain strainers/stoppers with bigger holes. Neither a bathtub or sink overflow will do any good if the trap is clogged. This means, that even if you could add an overflow with a drain assembly like a bathtub, it would not help with the actual problem that the "overflow" is designed for. In order for the overflow to help this problem, the "overflow" has to be connected to the drain immediately below the strainer, so that the air has somewhere to escape. The strainer, and the water trying to go down the drain pipe, trap the air directly under the strainer, causing a big air bubble, which causes an air lock, and keeps the sink from draining very well. The water wants to go down the drain, but the air wants to rise to the surface. Then the water goes through a strainer at the drain that has too small/many holes in it. The water goes through an aerator as it comes out of the faucet, and obviously, there is air in the drain between the trap and the strainer before you turn on the water. The problem with vessel sinks is that the cute little strainers and small drain pipe cause an air lock. Saying that "Vessel sinks will not drain properly because they do not have an overflow" is a bit like seeing two red cars get into an accident, and concluding that they crashed because they were red, but you will read it often. The confusion comes from the fact that vessel sinks would benefit greatly from having an overflow. Many, if not most, lavatory/sink overflows are not big enough to keep the sink from overflowing if the water was left on at full force, and a stopper in the drain hole. You would know if you had the other kind because you would be cleaning the hair out of it every few weeks. What is worse, it will probably overflow inside the wall, behind the trip lever (on some models), long before you notice it anywhere else. The bathtub would still overflow if you left the water running. The funny thing is that, by far, the most common waste and overflow assembly used for bathtubs does not allow water to drain out of the overflow either when the stopper is engaged. Out of a few different major plumbing codes in the US, only the IRC/IPC requires overflows, but just on bathtubs. The only difference between bathroom sinks and other sinks is the size and type of strainer going into the drain. I have never seen an "overflow" on a kitchen, laundry, or bar sink, so it is not really the code requiring it, but the confusion by the local inspector. The codes, and calling them an "overflow" in the first place is what causes all the confusion.
