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

If you have a sticky flush lever it’s time to inspect your gasket. Slipped this on to fix my Mansfield. Perfect fit that works like a charm.

have an older mansfield 160 fit and worked perfectly

I used to be able to buy these at the local hardware store, but they are no longer stocked nor is an acceptable replacement. Anyway, these gaskets fit the flush valve on my Mansfield toilet and stopped the constant draining. I tried a gasket from another manufacturer, but they didn't fit properly and made things worse. I will be buying these again then next time one of my toilets starts leaking at the flush valve.

Perfect fit and seal for out Mansfield flush valve. Easy to install. Good quality

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!
