Slowly open the main shutoff valve to let water into the sprinkler system. Turn off the water to the entire sprinkler system. In most cases, the water pressure settings should be somewhere between 40 and 65 psi.
Third, check that the side of the valve has a test port and what you need to turn each of them off with a screwdriver that places at an angle of 45 degrees. To find out if they are turned on all the way, locate the two valves. Most automatic sprinkler systems are set up with two types of valves. The solenoid is the cylinder looking part of the valve with the two wires sticking out of it as seen below for most valves.
Locate the manual control knob on the top of the sprinkler valve. Set the system timer to run a manual test of all of the sprinkler zones, running each zone for about 3 to 5 minutes. Checking lawn for frozen ground Often the valves are not on all the way so checking these is important.
Then manually turn on the valve you want to remove, the sprinklers will come on for a few seconds then slowly shut off as the water discharges from the pipes and the pressure is released. This is the fully open position. Use a sprinkler valve key to turn the valve clockwise until it stops. Locate and turn off the main water valve for your sprinkler system by turning the valve in the clockwise direction until it is fully closed.
Whichever valve you are turning on, it is always safe to manually turn on sprinklers and make sure to open it slowly, give it time to pressurize before opening it all the way. The picture below explains how check valves work and what it does. A check valve simply maintains a one-way flow of water. Just remember that a PVC check valve is made of plastic, not copper or any metal. Please find a picture and details of a PVC check valve in this Amazon product link. Now that we know what a sprinkler valve is and what our options are, we can talk about how to install it.
Installation is straight forward. The valve leaks here and there if the height does not meet the requirement. We installed the anti-siphon version first and then had to replace it because we did not maintain the height requirement.
Since our plumbing system already has an anti-siphon mechanism, we then decided to use a regular sprinkler valve.
Always apply PTFE seal tape on the male thread. Twist the male thread into the female thread of the valve and then hand tighten. The installation setup for an anti-siphon sprinkler valve is shown in the image below.
A PDF version of the image is uploaded in this link. The PVC pipes will directly go inside the Slip side of the adapter and be glued. How to glue is not explained in the picture below but it is explained in another picture later in this post. Installing a regular sprinkler valve is easier than installing the one with anti-siphon mechanism.
You can install a regular sprinkler valve within the line without raising the level of the valve. The installation process is depicted in the following picture. Again, the PVC pipes will go inside the slip sides of the male adapters and be glued, which is not explained in the image below.
We have uploaded a PDF version of the following figure in this link. If you use a regular sprinkler valve without anti-siphon , I recommend that you include a check valve to prevent back-flow even if you have an anti-siphon mechanism already installed in your line.
You do not need a check valve if you use the anti-siphon version. Additionally, we learned the hard way that it is better to make the setup easily changeable. What do I mean by this? Unions can be twisted and separated from the line easily.
A picture of a PVC union we used is as follows in its open form. The following infographic representation shows how we may set up all these items when using a regular sprinkler valve.
The picture also provides information regarding gluing and sprinkler wiring. Notice that you can twist the two PVC unions to detach the sprinkler valve and install a new one without any necessity to cut the PVC pipes. A PDF version of the following figure is available in this link.
There is a special wire available for sprinkler system wiring. Or, you may purchase from Amazon. Notice that you can now easily replace the sprinkler valve if it malfunctions. Why should we miss all the fun, while we can do it ourselves this easily? This is very useful and helpful to us. At glance its kinda hard to understand but if you focus yourself on it, its easy to assemble the parts. Now I have better understanding how to do it, how does it work and probably be impressed by Mom if I do it in her garden maybe some kind of extra income as well.
Thank you for sharing that brilliant idea. These tips and options tou gave is very informative. Thanks for the easy steps on hiw to do it and may you have more followers because you spent your time to post such relevant topics.
Thanks mate! Thank you for your kind words. I am glad to know that you found this post informative. Have a great week. Its very useful and very timely for me hahaha.
Glad that i checked your post and read this. Continue the great work and post more helpful informative stuff. I have a vegetable patch in the backyard, I grow vegetables all through the year. I grow seasonal and perennial vegetables.
I water my plants manually, I plug in water pipe on the tap, turn on the tap and then water my plants. I did not know I can automate the process by using sprinkler valve. I will have to read this again. I would like to have it my front yard it would be nice to see it, it is like a fountain in my yard.
This is educational, the way you show us how to do it and with an image, it is easier to understand and to follow. Nice presentation and instructions on your post. I really learned a lot. Thank you and have a nice day. A detailed informative post providing me with a ton of information. The pictorial representation is quite helpful. Thanks for describing the procedure in a lucid language. Thanks a lot!
Can one person alone set all this up? One person can set it up alone. I did it myself. We had to make a U-shape with our pipes to get the box to fit where we wanted it. Once the glue was dry, we tested the whole thing by turning on the water valve that yellow handle. The sprinkler valves are closed until you tell them to open with an irrigation timer , so everything should stay nice and dry. Lucky for us, it did. One final thought: connecting to the water main in this house was difficult, but each step after got easier and easier.
Installing irrigation valves is definitely something any homeowner can do. Like this idea? Click here to subscribe to Simple Practical Beautiful for more!
