One of our toilets barely flushes. It's not the flapper type of insides it's a mansfield toilet and the kind of insides that slide up and down to cover the drain hole. The tank fills full but when it's flushed only about a quarter of the tank is emptied before the thing slides back down and covers the drain. Is this adjustable? The wrong type ? Need to be replaced? Thanks

Is this tha flush valve that you have,(see image)?
When you find the flush valve overflow pipe rises as you turn the flush handle, you have to unscrew the small (one inch) disk on the top and lift the entire overflow pipe up and out of the toilet in order to remove the replaceable valve seal on the bottom. This type of valve comes in both plastic and metal. But both have a large rubber disk on the bottom that pulls off. Good luck, Tom
