Plumbing 0030 Flush Valve Service Pack, Fits 210/211 Flush Valve

The seal fit perfect and the leak stopped immediately. I really believe the new seal is designed and made better than the old one.

This is a real Mansfield product. It is made from a different type of rubber than the aftermarket alternatives available in the big box stores (which only last for about a year). The instructions are clear and easy to follow, and it only takes a couple of minutes to change. The videos on the product page are particularly helpful. If you are changing the flush valve tower, I recommend always changing this seal at the same time, it is very cheap insurance!

worked great stopped leaking and only 2 minutes to change

Products fit fine in both cases and took less than ten minutes to replace the seal and broken flush handle. Stopped toilet leaking and repaired broken flush rod. Saved a big plumbing expense.

While instructions for replacing the seal ring are printed on the back of the package, I would highly recommend that you watch the helpful videos on youtube before you try it the first time. Just search for: Mansfield Toilet Repair. For the video that most clearly shows how to install the seal ring (provides clearest image of the proper groove), search Google for: Mansfield Flush Valve Seal Video Grigg. This is the Mansfield OEM (original equipment manufacturer) replacement part (630-0030) for the flush valve seal ring for Mansfield 210 or 211 flush valves. If your Mansfield toilet leaks or is difficult to flush, then replacing the flush valve seal ring will probably fix the problem. I need to replace the seal ring every 2 to 12 months in my two Mansfield toilets, so I now keep at least 6 spare seal rings on hand just in case. Dear Mansfield: Please provide a seal ring that will last longer! If you have decided to replace the seal ring you might first try removing it, flipping it over, and reinstalling it. Sometimes this works, sometimes not. The two most important points to note: (1) the new seal ring fits into the TOP groove around the flush hole (when properly installed, you can rotate it with your fingers); and (2) the flush valve "stop cap" (the white or blue circular plastic piece that the refill tube is inserted into) unscrews, it does NOT pull out (if you try to pull it out, you will break it). If you want to know the model number of your Mansfield toilet, the number should be impressed into the lid of the tank (for example, 160) or it will be printed on the inside back wall of the tank. If you want to determine the model number of your flush valve, it is impressed on the black plastic body of the flush valve (you will need to remove it from the tank to see it). To read other people's experiences, search: Mansfield Toilets problems. Many people (including myself) have concluded that use of bleach tablets in the tank (for self-cleaning) may cause early failure of the seal ring. Also, hard water seems to cause the rings to fail sooner. If this ring becomes distorted or degraded, water can leak past the ring resulting in periodic re-filling of the toilet (you hear the water turn on and then off from time to time as the tank refills for lost water). Seal ring distortion can also cause a vacuum to form under the flush valve, making it very difficult to raise to flush the toilet. A very strong house guest applied so much force in his attempt to flush one of my Mansfield toilets that he broke the flush lever and the flush valve's stop cap!

Stop the running! My toilet used to run, at first just once in a while, but later when the water company started providing hourly updates on water consumption, I noticed that sometimes I would use 7 gallons an hour when I was sleeping or not even in the house. I replaced the old seal with this one, and my water bill dropped by 35%, Shocking! So it cost justified in 1 day. Make sure your have the correct Mansfield toilet and find a couple of videos on how to replace it. (The first video I found was overly complex, I found another video which showed me the easy way)

Bought one of these for 2.99 on ebay and one on amazon for 4.79 (had an amazon gc or would have done ebay). Both fixed my mansfield hard to flush problem. It's pretty easy to install too... here are the steps. Sounds a lot harder than it is takes about 10 minutes, 15-20 if you wipe down the parts while you're inside the tank. 1. Turn off the water valve all the way (under one side of your toilet) 2. flush until you get all the water out (well you wont get the last 1/4 inch) 3. Take tank lid off 4. Pull out house connected to circle piece on top of cylinder 5. Unscrew that circle piece with your hands like you are opening a bottle 6. Lift up cylinder a bit and turn to the right and pull the flush stem out through the square. 7. Pull Old Red Valve Off (Black might cloud water from touching other seal) 8. Put New Valve On In Top Groove, Use 2 Hands, Stretch A Tiny Bit Around Groove... 9. Make Sure It's On Right... If It's In Right You Can Move Around Clockwise and Counter Clockwise. 10. Put Back On Cylinder and Make Sure The Flush Stem Is Through the Square Loop Of The Cylinder 11. Screw Circle Piece Back On Cylinder 12. Put Hose Back In Top Of Circle Piece You Just Screwed On 13. Level Out Flush Handle And Tighten Back Up The Inside Plastic Nut To Make Sure It's Tight (can get loose replacing valve) 14. Turn Water Valve Back On 15. Flush A Few Times To See If It's Easier To Flush & The Water Is Stopping About At The Same Line It Was Before.

I don't think these are made to spec. They leaked, ALL OF THEM.
