Drip irrigation is one of the most effective and efficient methods for watering a garden. Through a drip irrigation system, water is directly able to reach all of your plants in the right quantity. Drip irrigation systems deliver water through their valve. Valves can wear out or need repair over a period of time. The repair can be something as simple as a rock possibly being stuck in the valve’s solenoid. Depending on the type of drip irrigation system you have, you can usually do the valve repair yourself.

There are many types of drip irrigation valves available to irrigate your farms. Most drip irrigation valves come with a controlled shut off and an emergency shut offs. There will be times that you will have to repair or even replace a broken drip irrigation valve.

    Step 1 – Shutting Off the Water

    Turn off the sprinkler system. To keep water pressure from causing damage to the system from building up, shut off the main water supply.

    Step 2 – Releasing the Drip Irrigation Valve

    The drip irrigation valve is similar to a cylinder with wire coming off of both of its ends. Once you have located the sprinkler valve, release it from the sprinkler head. Turn the drip irrigation valve in a counter clockwise position and it will pop out of place.

    Step 3 – Removing the Drip Irrigation Valve Components

    The drip irrigation valve sits inside of its housing. To open this housing, twist the top part of the drip irrigation valve until it is released. There should be spring as well as a flexible diaphragm in the valve. Remove these as well.

    Step 4 – Cleaning the Drip Irrigation Valve and Components

    Use a soft cloth or your fingers to remove dirt that may be in the diaphragm. Check the diaphragm and spring to see if there is any damage done to them. If there is, then replace them with new pieces. The housing and the valve should also be cleaned to get rid of any possible dirt. This dirt is what can possibly be causing the water to be blocked and making the drip irrigation valve malfunction.

    Step 5 – Putting All the Pieces Back Together

    Put the valve back together and put the valve back in the head of the drip irrigation sprinkler.

    Step 6 – Turning On the Water Supply

    Turn the water supply back on to the drip irrigation system. Test the system to see if it is working properly.
