Are Hunter sprinkler valves good?
Hunter Sprinkler valves provide superior flow control and are the heart of your irrigation system. From low flow to high flow, clean water to dirty water, low pressure to high pressure, every Hunter irrigation valve will work reliably for the lifetime of your irrigation system.
How do Hunter sprinkler valves work?
Water enters the valve from the system main line and exerts a force against the center of the valve’s diaphragm. A small orifice in the diaphragm allows the water to flow through to the upper chamber between the diaphragm and the bonnet.
How do you tell if a sprinkler valve is bad?
Signs of issues in sprinkler valve:
Water not turning Off: If you notice that water is not closing off from the sprinkler, then there seems to be an issue in the diaphragm valve. Leaks of water: Broken Sprinkler Head. Stuck Valve. Wiring: Irregular Watering:
How much should it cost to replace a sprinkler valve?
On average most homeowners pay $212 to repair a sprinkler system. Replacing sprinkler heads at $5 to $20 per head, or replacing valves at $20 to $40 per valve, not including the cost of labor of about $75 an hour by a professional, is what most sprinkler repairs involve.
How do you clean Hunter irrigation valves?
Wash the diaphragm with clean fresh water to remove any debris that may have been deposited there. The diaphragm spring should be intact and bounce back when compressed. Examine the valve body and remove any debris, pebbles, or dirty water. The seal seat should be clean and free of nicks, grooves, or abrasions.
What causes a sprinkler valve to stay open?
Air Trapped in the Valve:
The valves may have air trapped in them. A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.

There are three basic types of valves used in irrigation systems – gate valves, ball valves, and electric valves.
How do you turn on an irrigation valve?
Slowly open the main shutoff valve to let water into the sprinkler system. For a ball valve, turn the lever handle one-quarter turn until the handle is parallel to the pipe; this is the fully open position. For an in-ground shutoff valve, use a sprinkler valve key to turn the valve counterclockwise until it stops.
How do you adjust a hunter valve?
Turn the solenoid ¼ turn counterclockwise or open the bleed screw ¼ turn. When using this method, you will see some water trickling from the bleed screw and this is normal). To stop manual operation, tighten either the solenoid or the bleed screw to its original position. The valve will close within 15 seconds.
How do you manually turn on a Hunter sprinkler valve?
One way is to simply turn the solenoid (the black cylinder with 2 wires) counter-clockwise a 1/4 to 1/2 turn. To shut off the valve, twist the solenoid clockwise until it is snug on the valve. The other way is to use the bleed screw the same way, loosen the screw enough to release air (1/4 to 1/2 turn).
What happens when a sprinkler solenoid goes bad?
Water leaks: High pressure from a broken solenoid can put a lot of stress on your sprinkler system and burst small or large leaks throughout it. Low water pressure: Low water pressure can be just as much of a problem.
How do I know if my solenoid valve is working?
Sometimes you find a normal read on the digital multimeter but the coil is actually not functioning. At this time, you can use a screwdriver and put it near the armature then energize the solenoids. If there is a magnet in the presence, the coil is good. Otherwise, it is bad, and you need to change a new one.
