Why do I have hot water in my toilet?

You may have hot water in your toilet because of a bad flapper in the toilet tank or a bad fill valve. When a toilet has a mixing valve (to prevent condensation), a little hot water is added to bring the temperature up. When this system is not functioning correctly, you can get a bowl full of hot water!
