The bleed screw on a sprinkler valve is an important component that serves a specific purpose in the irrigation system. When it is opened, it allows water to “bleed” or escape from the upper pressurized section of the valve. This action enables water to flow through the valve and ultimately reach the sprinkler heads to irrigate the desired area.
One way to understand the function of the bleed screw is to think about the valve as a gateway that controls the water flow. When the sprinkler system is in operation, water is pressurized and needs a way to pass through the valve and reach the sprinkler heads. However, if the valve is closed, the water cannot flow freely, and the sprinklers will not work properly.
By opening the bleed screw, you create a small opening or pathway for the water to escape from the upper pressurized section of the valve. This relieves the pressure and allows water to flow through the valve, reaching the sprinkler heads and effectively irrigating the desired area.
One practical situation where the bleed screw comes into play is when you need to manually activate the sprinkler system. Sometimes, after the system has been turned off for a while, air can get trapped in the valve and prevent water from flowing smoothly. In such cases, opening the bleed screw can help release the trapped air, allowing the water to flow freely and ensuring proper irrigation.
It is important to note that the bleed screw should only be opened when necessary, such as during system activation or troubleshooting. Leaving the bleed screw open for an extended period can lead to water wastage and potential damage to the sprinkler system.
The bleed screw on a sprinkler valve serves the purpose of relieving pressure and allowing water to flow through the valve. By opening the bleed screw, you create a pathway for water to escape from the upper pressurized section, ensuring proper irrigation in your garden or landscape.
