Rated 5 out of 5 by So far , so good! Leaky running Mansfield. Easy repair. Hard part to find though. Thank you to the advice in this section. Saved my insanity! November 16, 2014
Rated 1 out of 5 by Only get the original factory Mansfield brand seal! I go through these seals like crazy and know which ones to buy. If you buy a non-factory brand, it will not last! Get the original factory Mansfield brand and it will last a lot longer than the off-brands. The Mansfield brand is not easy to find, but when you find one, buy a spare. October 1, 2014
Rated 1 out of 5 by Mansfield Design is horrid I have replaced the whole flush valve and the seal with Mansfield parts twice and it still leaks at the red seal. I feel the design of the flush valve is just plain bad. I have tested this over a 5 gallon bucket and had enough water in the tank for the weight to push down on the flush valve. It still has a slow leak no matter what Ive tried. Im never using a Mansfield flush valve again doesn't matter if its OEM parts or a different brand such as this. This is the only place I can review without a login... November 17, 2014
Rated 5 out of 5 by WOW! Actually Fixes the Mansfield HARD to flush problem I saw that others had indicated that this was a possible fix for a hard to flush Mansfield 210/211 Toilet Flush Valve. I didn't see how this Flush Valve Seal could possible work, but sure seemed worth a try versus cost of a plumber. Jimminy Cricket! and Geeze Louise! it really is the correct solution. If you were a plumber and did this all day you could probably do the change out in 10 seconds. I changed out 3. First one was a learning curve and took about 10 minutes, then second one took about 3 minutes and last one took under a minute. Apparently this Flush Valve Seal breaks down from something in the water it does not like and gets a cupped shape and creates a suction seal which makes it extremely hard to push down the handle and flush. Made a believer out of me and definite *YES* it WILL fix a hard to flush problem with a Mansfield Toilet Flush Valve. I didn't even need any tools after I understood how everything worked.

Rated 5 out of 5 by easy and cheap repair This gasket will fix the sticky valve problem and water leakage. Make sure to install in top groove of housing not lower groove. You should be able to spin the gasket around housing after it is in groove properly. A butter knife might help in getting into this groove. Failure to get in top groove will result in water leakage around seal. Complaints of water leakage after installation is probably because of this. This is a very easy fix so don't put it off. Rate of gasket deterioration will depend on your water but replacing it once a year is probably average. April 24, 2014
