What causes toilet to keep running after flushing?

Turn off the water and drain the toilet.
The flapper is a round rubber seal that stops water from draining from the tank and into the toilet bowl. When you flush the toilet, the chain pulls the flapper up so fresh water can fill the bowl. Problems with the flapper are among the most common causes of a running toilet.

What is a toilet flapper?

The flapper (aka “flush valve seal”) is the plug that falls against the drain hole (flush valve drain seat) on the bottom of the tank and holds water in until the next time you flush. If you've tried replacing toilet flapper but the toilet still runs, the flush valve seat is probably rough or pitted.

Why is toilet not filling with water?

Adjusting the Fill Valve
If the toilet still proceeds to not fill properly from readjusting the float ball, then the problem may be resolved by adjusting the fill valves. Toilet fill valves control the flow of water from the supply line to refill the tank between flushes.

Why does toilet run every 5 minutes?

toilet runs every 5-10 min for 30 secs. your toilet is "cycling" because water is slowly leaking out of the tank during those 10 minutes. The most common cause of this is a leaking flapper valve. Put some food colouring in the tank water and see if the bowl water changes to the same colour.
