How to set up a Fusan anti siphon valve?
Setting the valve is pretty easy. Turn off all the water supplies in your house and drain any excess water. Then open the spigot and secure the valve in its place. Run the valve to check and you’re good to go!
In this article, we’ll discuss how to set up a Fusan valve. From the required tools to the necessary steps. Let’s begin!
How Do Anti Siphon Valves Work?
Before we get into discussing the steps, we need to understand how the valves work. They play a crucial role in keeping the water clean. For this reason, most plumbing codes make it mandatory to use an anti-siphon valve.
Anti-siphon valves prevent water from flowing back. Thus, they ensure the water only flows in one direction. During irrigation, it prevents the water from siphon back into the supply line due to pressure.
An anti-siphon valve helps prevent backflow. Thus, ensuring consistent water pressure. It’d be ideal if you have problems with the pressure regulator.
If you have an outdoor garden, an anti-siphon valve is a must. It prevents any dirty or fertilizer-infused water from the sprinklers from getting into your house. Whenever there is pressure from the opposite sides, the valves close to prevent backflow.
How to Set up a Fusan Anti Siphon Valve
It’s time to set up our valve. Setting up is fairly simple and can be done without a lot of plumbing skills. However, you have to be careful throughout the entire process.
Step 1: Turn Off The Water Sources
To begin with, make sure all the water sources are turned off. Go to your main water shut-off valve and turn it off. If your PVC shut-off valve is stuck, you need to deal with that beforehand.
Once the water supply is turned off, make sure there’s no water in your pipes. Disconnect all the hose pipes and turn the taps. Let the taps run until there’s no water left. Once all the water is gone, move to the next step!
Step 2: Open the Spigot
Choose the spigot where you want to attach your anti-siphon valve. It’s better if it’s near the sprinklers. You have to remove it and place the new valve. The best way to remove it is with an adjustable wrench.
Take the wrench and turn the spigot clockwise. Once it loosens up, remove it from its position. Now cover all the loose pipe threads with Teflon tape. Once the spigot is opened, we can move to the next step.
Step 3: Screw in The Pipe
The anti-siphon valve will be connected with a pipe. So, you need to connect the pipe first. You can choose any kind of PVC pipe that works with the rest of the system. Put the pipe in place and screw it tight.
Then, with a pipe wrench, tighten the pipe carefully. Keep turning it anti-clockwise until it’s set. It’s suggested that you use a good pipe wrench to get it done.

Once the pipe is tight in its place, secure it with more plumbers tape.
Step 3: Place the Valve
With the pipe in place, we need to connect the valve. The application of the valve is similar to that of the pipe. Place the pipe in place and screw it in. You can use a pipe wrench here as well.
Once the valve is attached tightly, you’re good to go!
We recommend that you add some extra Teflon tape. This will strengthen the pipe for the better. But, be careful while using the Teflon tape too much tape can cause waterlogging.
Step 4: Turn the Supply Back On
Now that everything is done, turn on the main water valve. Check if everything is running smoothly. Keep the anti-siphon valve running for a few minutes to see if it’s working.
With that, we’ve discussed the steps to set up the anti-siphon valve. We hope you find this helpful!
Question: Do you need an anti-siphon valve if you don’t have a garden?
Answer: In most cases, yes! Most plumbing codes recommend that you use an anti-siphon valve if you have a yard. Not using it could result in fines and penalties.
Question: Can your valve get damaged due to cold?
Answer: If there’s too much cold, your valve can stop working. For this reason, we recommend keeping the valve covered to prevent getting too cold.
Question: Is an anti-siphon valve the same thing as a backflow preventer?
Answer: The term backflow preventer is an umbrella term for a number of products. There are anti-siphon valves, faucets, etc. along with other similar products. So, while they are used interchangeably, they aren’t similar.
Anti-siphon valves are important for any plumbing system. And the Fusan anti siphon is one of the best out there! If you’re struggling to set up your valve, we hope this article helps you!
