a valve that regulates the water level in a toilet tank by using a floating ball to control the flow of water from the supply line
A ballcock is a mechanical device used in toilets to control the water level in the cistern. It consists of a float ball attached to a valve, which regulates the flow of water into the tank. When the water level drops, the float ball moves downward, opening the valve to allow water to fill the cistern. Once the tank reaches the correct water level, the float ball rises, closing the valve and stopping the water flow. Ballcocks help ensure that toilets refill properly after flushing.
- The ballcock in the toilet broke, causing the cistern to overfill with water.
- He had to replace the ballcock because it was leaking water continuously.
- The plumber recommended fixing the ballcock to prevent the toilet from running constantly.
- She noticed the toilet wasn’t flushing properly because the ballcock wasn’t working.
- The ballcock automatically shuts off the water when the cistern reaches the right level.
