When it comes to toilet repair issues, it’s useful to know what’s on the inside of the tank that can be causing the problem. Get to know your flappers, fill valves, flush valves, and handles so that next time your toilet isn’t working, you’ll know how to fix it yourself. The two main parts of the tank that cause problems are the flush valve, which lets water gush into the bowl after flushing, and the fill valve, that allows the toilet to be refilled afterwards. Here is how to fix them yourself:
