Here is a link to the funky Mansfield valve to buy. amzn.to/4c9QPGe
Mansfield Toilet is a popular brand. Maybe you've never seen a Mansfield Toilet valve. To be honest I had not either until I went to repair my mother-in-law's leaking toilet. I quickly identified the toilet valve as a Mansfield toilet. The rubber washer just needed to be replaced. The red washer could have been any color but a red or black washer would be the most common. This toilet was installed in the 1970s and may have been more popular at the time. The gasket can be purchased at Lowe's and Home Depot as well as online. It's easy to change and you'll see that I did not even turn off the water! Keywords include weird bell valve toilet, toilet valve leaking, identify toilet valve, ghost flushing. 1970s, 1980s. It was easy to fix this Mansfield Toilet/Mansfield Potty. Weird looking toilet valve.
