Irrigation Valve Stuck Closed

Some valves use a bleed screw to manually open them so if you dont see a lever labeled onoff or openclose look for a screw typically the screw has a knob handle to allow it to be twisted by hand. If the valve moves at all add a little more penetrating oil to it.

Take a cordless drill or screw driver and locate the four bonnet bolts on the top of the valve body.

Irrigation valve stuck closed. Air Trapped in the Valve. Opening a valve under pressure is dangerous and you could be injured. Rarely do I see it stuck closed as I do with the irritrol solenoids.

Finding the Valve First you need to find the valve. Since the water flowing through the port is what holds the valve diaphragm closed the valve stays open. Turn off main water supply to sprinkler system after identifying the trouble valve.

The valves may have air trapped in them. Rotate the manual onoff lever under the solenoid until its closed. I have learned over the years that if a DV valve is stuck open to try the solenoid first before taking it apart to replace the diaphragm.

A broken valve can mean water will not shut off automatically. Likewise if the handle is perpendicular to the top the valve is closed. When this happens try turning the tab or ring on the black solenoid on top of the valve clockwise until the water shuts off.

At this point open the manual flow control knob as far as it will go. Try to open the stuck valve now that the oils had a chance to work. After the water is flowing through the valve shut off the solenoid.

Its also possible that there is debris in the valve which is causing the diaphragm of the valve to remain open. Go to each valve and rotate the manual onoff lever to the on position. Identify the valve that is giving you trouble by locating the valve box and manually turning on one valve at a time with the bleeder screw or lever.

The valve should come on and sprinklers start to run. But the reading will still be showing good. To open a stuck gate value you need to follow the steps suggested below.

Ball valves are perhaps the easiest valve to see if they are open or closed. Tap again with the hammer to help the oil work its way into the valve. Every sprinkler system relies on valves to control the flow of water to individual zones.

Valves of the sprinkler may be stuck due to pieces of stone in them and refraining to be closed completely. Do not fully remove a. Unscrew the solenoid by turning counter-clockwise cylinder with two wires and make sure the plunger is clean and moves freely.

SHUT OFF the main water supply. If the gate valve becomes jammed or stuck and remains closed the gate valve stops operating and blocks the water from entering the water tanks. Try manually opening the valve using the onoff lever on top of the valve body.

Common places you might find a ball valve are in irrigation and in sites where you need to control water supply from one area to another. If this is the issue in the diaphragm of the valve then unbolt the solenoid to release the pressure. A small bubble of air becomes trapped in the tiny water ports of the valve this stops the water from flowing through the port.

If some kind of debris - sand silt solder etc - gets past the screen it can jam the plunger. If the handle on top is parallel to the valve its open.
