Review on 🚽 Mansfield 210 & 211 Flush Valve Rubber Seal Gasket Replacement - 2 Pack (Mansfield Flush Valve Seal) by Rubeen Black

Working. Somehow I'm going with three stars as I'm not sure if my problem is related to anything other than the shim itself. Flushing the toilet was a real agony, the old gasket was worn out and the valve was sticking around it. I bought a replacement and it seems to work. until I heard the toilet run every 30 minutes. After researching, I found that the smallest drops of water slowly seep into the bowl. This never floods the toilet, but the tank does need to be refilled from time to time.
