Review on Korky 5030BP Universal Toilet Flapper by Keith Howe

Update: This is a one size valve that leaks. I replaced it with a regular damper and that fixed the leak. This product is good quality but does not provide a good seal after each flush and leaks a lot of water. My water bill has increased by 30%. The seal between the tank and the bowl is too big and the tank is loose. It's not a big problem, but leaking water gets pretty expensive. I'm upgrading 2 more stars because it leaks very often and sometimes runs for hours before I realize it. This gives me very high water bills. The lid does not lie flat. It stands at an angle and cannot be adjusted in any way. Even if it looks like it should be sealed, it leaks. Now I have to do everything again :(
