DIY Frequently Asked Questions / My toilet is constantly running causing ripples in the bowl. What’s wrong?

Either the float on the fill valve is stuck or it is set too high, causing water to overflow from the tank into the bowl through the overflow tube. Check the float on the fill valve to make sure it isn’t getting stuck on anything. Next, check for mineral build-up on the body of the fill valve, which may be causing the float to stick. This can be removed with steel wool or fine grit sandpaper.
