Inlet Valve
Definition and meaning of Inlet Valve in real estate.
An inlet valve is the mechanical assembly inside a toilet tank that controls the flow of fresh water, automatically refilling the tank after each flush. It connects directly to the home's water supply line via an external shutoff valve located beneath the fixture.
In more detail
Commonly referred to as a fill valve, this component is critical for the proper and efficient operation of a home's bathroom plumbing. The valve utilizes a float mechanism, such as a plastic cylinder or a floating ball, to monitor the water level inside the tank.
When the toilet is flushed and the water level drops, the float sinks, opening the valve to let water in. As the tank fills, the float rises, shutting off the valve once the water reaches the target level to prevent overflows.
