Last night, I noticed my upstairs master bathroom toilet was running, so I thought it might just need a new flapper. However, when I woke up this morning, there was water all over the bathroom floor! The toilet bowl and tank were both overflowing, and water leaked through the ceiling downstairs. If I had known this was coming, I would have turned the water off right away. I've never experienced something like this before—what could have caused it, and what should I do now?

First thing you should do is check with your insurance to see what they will cover. If they don’t cover the expenses for cleanup, consider renting some powerful dehumidifiers and running them for about a week. This helped me a lot when I had a flood situation. Also, it’s a good idea to get some leak alarms and place them around critical areas like the toilet and washing machine to prevent future disasters!
What brand or model is the toilet? Generally, when the tank overfills, the excess water should drain into the bowl. There are a couple of parts to consider: the tank has a valve that connects to the handle and a tube that almost reaches the top. If the float mechanism fails, water can overflow. It's also worth double-checking if anything has fallen into the tank, like a plastic bottle, which can block the fill valve. Here’s a diagram of the toilet parts for reference: [toilet parts diagram].
It sounds like the flapper might have gotten stuck open, which could explain the overflow. But since the toilet bowl is backing up, there could also be a blockage somewhere. If your cesspool is full (if you have one), that could be causing the issue too. It's definitely unusual to have both problems happen at the same time, so I'd recommend calling in a plumber to check it out before you try any fixes yourself.
