Understanding Automatic Sprinkler Valves with Sprinkler Master Repair (Fresno, CA)

There is a lot to understand when it comes to the components of a sprinkler system. At Sprinkler Master Repair (Fresno, CA), we not only care to provide you with quality service, but we strive to teach quality service as well. A job is still half-complete if you didn’t learn something along the way, so today we are here to help you know all you need to know about automatic sprinkler valves, and what they do for your lawn! If you want to get in touch with Sprinkler Master Repair (Fresno, CA), simply give us a call, at (559) 422-3808.

The Automatic Sprinkler Valve Purpose

The purpose of an automatic sprinkler valve is to turn the water on or off to the sprinkler zones.

Names of Parts

  • A solenoid is a device that lifts a cylindrical metal bar up and down through electromagnetism. When this cylindrical bar raises, it allows water to flow through the valve. The majority are actuated with 24-volt ac electricity.
  • Valves also have bleeder screws that allow manual operation of the valve. The bleeder screw is small, and when it is unscrewed to allow air into the top of the valve, it then allows water to flow through the valve.
  • Another feature some valves have is called flow control. This is a small gate valve that when screwed clockwise restricts the flow of water, and when turned counterclockwise, allows water to flow again. A valve can be turned off all the way within the flow control.
  • On the inside of the valve, there is a rubber diaphragm and a spring that is used with the valve parts above to help control the water.

Common Brand NamesFresno CA Sprinkler Master Automatic Sprinkler Valves

Part Names

Casing: The plastic outside containing all of the internals.

Wiring: The electrical connections allowing the valve to function.

Diaphragms: The rubber piece inside that lifts or falls, allowing water to flow.

Solenoids: A metal rod that is lifted or dropped by electric flow allowing the diaphragm to move.

Flow Control Screw: Screw on the top of the housing that allows the pressure to flow through the valve without the solenoid being actuated.

How Automatic Sprinkler Valves Work

An automatic sprinkler valve is electronically controlled. A sprinkler timer tells the valve to open or close using 24v ac electricity, with the solenoid allowing the diaphragm to open, and water to flow through. Valves can also be turned on manually with the bleeder screw turning it a quarter turn counter-clockwise.

Pros and Cons

  • Automatic sprinkler valves can be turned on and off electronically or manually.
  • They can be battery powered.
  • There are many different brands and styles, but all use the same universal functions of having a diaphragm and a solenoid actuating them.
  • When there’s any electrical damage, valves will not turn on. This can include hard water residue build-up on solenoids.
  • Valves being stuck on are usually caused by torn Diaphragms, dirt or rocks ruining the valves, solenoids breaking off in the valve, and the flow control getting stuck in the closed position.

How to Diagnose Automatic Sprinkler Valves


  • If the valve does not turn on, it’s most likely an electrical issue.Fresno CA Automatic Sprinkler Valves
  • Start by turning on the clock for that zone, then feel the solenoid with your hand. If you feel a small vibration, the solenoid is on and functional. If so, check the flow control. Turn the flow control counterclockwise as much as you can. If the valve still does not turn on, unscrew the solenoid by turning counterclockwise.
  • If there is still no flow, use the bleeder screw. Manually turn on an adjacent valve to ensure that you’re getting water pressure. If the valve is installed backward, water will never flow through. At that point, if none of those work, replace the diaphragm and clean the valve out. If that still does not work you’ll need to replace the entire valve. Make sure there’s water pressure running to it.


  • If it’s an electrical issue and you’re not getting power, You need to do deductive reasoning to find out which of the three possible problems you’re dealing with. Those possible problems are; the solenoid is bad, the wiring is bad, Or, the timer is bad. We cover more detail on electrical later in the course.
  • If a valve is sticking on and is getting power, you will need to replace the valve or rebuild it.
  • To rebuild a valve, you will first need to unscrew the screws, take off the top, and take out the internals. Remember exactly how you took it apart. Replace all the internal parts, the solenoid, manifold, spring, and top of the valve, and screw the assembly together again. Remember if you replace any parts of any valve to match it with the exact same brand and model. If any parts are mismatched or improperly installed, it will probably not work.
  • To replace a diaphragm, take apart as shown in the video, and simply place the new diaphragm in place of the old one, and reassemble the valve.
  • To replace the solenoid, remove the wiring, unscrew from its housing, and screw the new one into place, and connect the wiring using waterproof wire nuts
  • If the valve is damaged or cracked it is best to replace the entire valve.

Tips and Tricks

Always try to use waterproof wire nuts on your electrical connections. They’ll hold up better in the long run. Also, the easiest way to see if the valve is getting electricity is to activate it via the timer and feeling if the solenoid vibrates. If it doesn’t, you need to check the wiring. If it does, there’s a problem with the valve internals.

10 Ways a Great Lawn Will Make Life Better!

Top Advantages of a Beautiful Lawn

Happy Family Playing in lawn Sprinkler Master Repair
A beautiful family having a great time on their luscious green lawn
A beautiful, lush, dense lawn has many great advantages. A home with an inviting lawn will welcome you and all of your guests. Here are a few advantages of a well maintained lawn.
Grass Cools Down Your Property
When the heat is on in the summer, grass keeps you cool. Front lawns of just 8 average houses have the same cooling effect as about 70 tons of air conditioning, while the average home-size central air unit has only a 3 – 4 ton capacity. On top of that grass acts as a noise reducer as it effectively absorbs and deflects sound. When combining a beautiful lush lawn with trees, shrubs and other landscaping a lawn can significantly reduce hard unwanted noise.
Enhances the Whole Neighborhood
Lawns can contribute to your sense of well-being. Most people say that the best place to relax is in their own backyard. A green, attractive landscape design goes much further than just relaxation and recreation. For example when the city installs landscaping and grass parks to enhance the area, people start taking pride in their surroundings and raise the bar of their own property maintenance. As well as, when I have a neighbor with a well-kept lawn, it encourages the rest of the neighbors to do a better job and in return the whole neighborhood benefits.
Easier to Sell Your Home
An attractive landscape can make or break a home sale. Landscaping can add tens of thousands of dollars to the value of your property. In fact, it is one of the few home improvements you can make that not only adds value immediately, but also increases in value as the years go by; while interior decor and design concepts regularly go out of style and mechanical systems wear out, plants grow fuller and more robust as the years go by. The home’s value is added at an advantage ranged from 5.5 percent to 12.7 percent. That translates into an extra $16,500 to $38,100 in value on a $300,000 home. A beautiful landscape design and healthy lawn is a good indication that they’ve taken care of the inside of the house as well and that the home is worth a premium price.
Grass Is A Pollution Fighter!
In one year the blades and roots of grass in an acre of healthy grass absorbs hundreds of pounds of pollutants from the air and rainfall. Among them are sulfur dioxide, nitrogen oxide, hydrogen, fluoride, nitrates and other gases blamed for acid rain and the greenhouse effect.
Grass Produces Oxygen
Grass plants remove co2 from the air and produce o2 in return. Just 625 square feet of grass supplies all the oxygen a person needs for one day. A 5000 square foot lawn produces enough oxygen for 8 people each day. In comparison, it takes two 100-foot trees to provide the same amount of oxygen for 8 people.
Grass Saves Soil!
A green lush lawn stabilizes the soil against water and wind. Lawns prevent runoff and erosion of our valuable topsoil, keeping additional phosphorus from entering our streams and rivers. A healthy lawn also traps much of the estimated 12 million tons of dust and dirt released into the US atmosphere annually.
Grass Has Better Rain Absorption
Healthy, dense lawns absorb rainfall 6 times more effectively than a wheat field, four times better than a hay field, and prevent runoff and erosion of our precious topsoil, keeping additional phosphorus from entering our streams and rivers. A healthy lawn also traps much of the estimated 12 million tons of dust and dirt released into the US atmosphere annually.
Grass is Mother Nature’s Carpet
Nature surrounds us, make yours stunning! Grass is used for recreation from family picnics to soccer to football to any other sport played on grass, grass is essential. It acts as a pad to reduce injuries that might have happened. A dense lawn is a far safer playground and playing field than nearly any other surface.
Hospitalized Patients Have A Faster Recovery
When the patient’s room viewed a beautiful landscaped area compared to patients with non-landscaped views a faster recovery has been observed in hospitals.
Grass Helps Fight Wildfires
With the weather heating up, wildfires are more prone to spreading. Help protect yourself with a lush green lawn. Grass is known to have a low fuel value which can actually help act as a buffer around your property in case of fire hazards.
