Slowly open the main shutoff valve to let water into the sprinkler system. The fully open position for a ball valve is when the lever handle is parallel to the pipe. Use a sprinkler valve key to turn the valve clockwise until it is fully closed. If the water level in the system is too low to allow sprinklers to be installed, you may need to add a second valve.
To do this, remove the first valve and replace it with a new one. The new valve should have the same size opening as the old one, and it should be located on the opposite side of the line from the original valve so that it can be easily opened and closed by hand.

How do I manually open my sprinkler valves?
To open the valve manually, twist the manual bleed screw counter-clockwise until the valve opens. It isn’t usually necessary to be more than one-half turn. The manual bleed screw needs to be turned clockwise until the water level in the tank drops to the bottom. If you don’t have a pump, you can use a garden hose to pump water into your tank. You can also use an aquarium pump if you have one.
How do you know if an irrigation valve is open?
The internal gate that releases water as it turns is lifted by turning it to the left. When the handle is turned counterclockwise, the gate lifts completely. If the handle will turn no farther counterclockwise, the gate will not lift, and the water level will remain at the same level as before.
If you want to turn it clockwise and then reverse the process, you can do so by turning it in the opposite direction. For example, if you wanted to raise the level of the pool by one level, turn the handles in opposite directions, then turn them back to their original positions.
Why is my irrigation control box full of water?
An irrigation valve box can hold water after a heavy rain or when a valve, pipe or fitting is leaking. If the valve box is always full of water and you have ruled out irrigation leaks, you might need to replace the French drain pipe.
If you’re drinking water from a faucet that has a leak, the water may be unsafe for drinking. Check to see if your water has been tested for lead, arsenic, cadmium or other contaminants.
How do you remove a sprinkler cover plate?
Pull the outer ring or skirt out by slowly pulling them down over the sprinkler head. Remove the cup from the sprinkler head by cutting it with kitchen shears or pruners. Simply cut the plate and skirt in half.
Can you manually open a solenoid valve?
Override is a method of opening a normally closed valve (power to open) without having power. A person can operate the valve by either hand or screwdriver with this mechanical device. This can be useful in case of a power failure. Solenoids are used in a wide variety of applications. They can be used to control the flow of water in pipes, valves, and other mechanical devices.
The manual override valve is located on the side of the machine. It is connected to the power supply and is controlled by a switch. The valve will close automatically when power is applied to it. Manual override valves can also be operated manually by the operator.
How do you fix a clogged irrigation system?
Open the gate valve at the water source or when using a water pump, turn the water pump on and run the irrigation system for at least an hour.
The acid-water solution will be brought into the system through the mainline if this is done. pH of your water is too acidic, you may need to add a small amount of sodium bicarbonate (baking soda) to the solution to neutralize it. You can also add sodium hydroxide (sodium carbonate) if you have a pH meter.
If you do not have pH meters, it is best to use distilled water to test your pH.
Why do irrigation valves get stuck?
One of the most common reasons for a valve to keep running continuously is the accumulation of debris in the diaphragm. The most common reason for a valve to stay on is that it has been damaged or worn out.
Do sprinkler valves need pressure to open?
The common sprinkler valves on the market require pressurized water to close properly — they generally should open without much problem; but when closing they need internal pressure build-up to keep them from closing too quickly.
This pressure buildup can be caused by a number of things, such as a leaky valve, a broken valve stem, or a valve that has been improperly installed. This can cause the sprinklers to overheat, which can lead to a fire or explosion.
