How to Fix Toilet Flushing on its Own
Does your toilet flush on its own? This is a problem known as ghost flushing. It signals that your flapper is leaking and needs replacement. Hearing your toilet running and wasting water is common when your repair parts begin to wear out.
However, did you know that the most common cause of a leaking toilet is your toilet flapper? Since you can hear your fill valve working, it is easy to assume that it is the main issue when your fill valve is doing its job of bringing water into the tank.
Shut Off the Water Supply
To start, turn off the water supply to your toilet. Look for the water shut-off valve on the wall or floor near the toilet's base. Turn it clockwise to shut off the water flow.
