A tap washer works by creating a seal that stops the flow of water when the tap is turned off.
Understanding the Basic Mechanism
Tap washers are typically found in traditional compression taps. Their primary function is to physically block the water path. When you turn the tap handle, it causes a spindle inside the tap body to move. A washer is attached to the end of this spindle.
Based on the provided information, the process of turning the tap off involves the washer moving into position to stop the water flow:
"And when i turn it off the opposite direction the white washer. Comes down until eventually it's pressing. Hard against those two edges."
This describes the washer's action:
- Movement: As the tap is turned in the "off" direction, the spindle lowers the washer.
- Sealing Action: The washer is pressed "hard against those two edges." These edges form the valve seat within the tap body.
- Result: The pressure of the washer against the valve seat creates a watertight seal, preventing water from passing through and exiting the tap spout.
The Role of the Washer
The washer, often made of rubber or a similar flexible material, is designed to deform slightly when pressed. This allows it to conform to the shape of the valve seat, ensuring there are no gaps for water to leak through.
How the Seal is Created
- When the tap is on, the spindle is lifted, pulling the washer away from the valve seat. Water can flow freely around the washer and out the spout.
- When the tap is off, the spindle is lowered, pushing the washer down onto the valve seat, just as the reference describes the "white washer" pressing "hard against those two edges." This compression blocks the water flow.
In essence, the tap washer acts as a simple, effective plug that is moved into and out of position by the tap handle to control the flow of water.
