How to Turn Off One Sprinkler Head

At FirePro Tech we know how much harm can be caused by the accidentally opened sprinkler head by releasing water. Knowing how to turn off one sprinkler head quickly can help minimize water damage and restore safety. This guide is made to help you learn everything about locating active sprinklers and the fire sprinkler system shut off valve so you can safely switch the water flow. 

How to Identify Which Sprinkler Head Is Activated

Before you know how to turn off one sprinkler head you should find out which one is actually active. Unless your system opens all sprinkler heads at once, there will be only one head spreading the water since most sprinklers are designed to respond individually to heat or physical damage. You can learn more about different types of sprinkler systems here. 

1. Look for water flow or spray. The active head will be spraying water forcefully, while others remain dry.
2. Follow the water trail. Trace the water flow and eventually you’ll find the source.
3. Listen for sound. If you’re sure the head is active, but there is no water at your sight, listen carefully for hissing or spraying sound. The source of them is usually the active head.

Now you know which head is the root of the problem, you can move quickly to shut it off by using one of our best methods. 

How to Locate the Fire Sprinkler Shut Off Valve

Every building’s sprinkler system has a fire sprinkler system shut off valve that controls the water supply. Actually, this valve is a main control point for the entire system. Learn how the fire sprinkler works, so you can easily recognize its parts. 

Here’s where to look:

• Mechanical or utility room. Most valves are located here.
• Near the water main. In homes and other residential buildings it’s wise to check the main water lines, since valves are often located there. 
• Ceiling or riser room in commercial spaces. Look for labeled pipes and red handles indicating fire sprinkler components.

Once you find a fire sprinkler system shut off valve, try to identify whether it has control over different zones or over the whole system. By switching off the valve that controls multiple areas you’ll leave them without water supply, so stay cautious. 

How to Turn Off a Fire Sprinkler Head Without Tools

Good news – you don’t have to be fully equipped with professional tools to know how to turn off sprinkler head and do it successfully. Here is how:

1. Locate the main valve. You sound to turn off the main valve, or sectional one in case your system has it.
2. Use a sturdy object. If the active sprinkler harms your belongings and equipment, try to cover it with a bucket or a board until you’ll safely switch off the water supply.

And that’s it! Of course, if your sprinkler head keeps activating randomly, you should call a trusted contractor like FirePro Tech.

How to Turn Off a Sprinkler Head Using a Shutgun or Wrench

A shutgun is a special tool made for sealing the orifice of an activated sprinkler head instantly. This device, just like  a wrench, can be a big advantage when deciding how to turn off the sprinkler system. 

Here’s how to use it:

1. Avoid standing directly under the water spray.
2. Align it with the sprinkler head’s opening.
3. Squeeze the trigger to plug the hole and stop the water flow immediately.

A wrench can also help you:

1. Carefully unscrew the activated head from the pipe fitting.
2. Be prepared for a brief water release before it stops completely.

Both shutgun and wrench will stop the water flow from the sprinkler. However, you still have to switch off a water supply and call for a professional to bring the system back to a reliable state.

What to Do After Turning Off the Sprinkler Head

When the threat is eliminated, there are a few things you can do to ensure safety:

1. Inspect the area. Check for any electrical hazards or structural water damage.
2. Dry the surroundings. Use towels or fans to remove moisture quickly.
3. Reset the system. When everything is safe and you’re sure the head won’t open again, switch on the water supply. 
4. Document the incident. Take pictures for insurance or maintenance records.

That’s what you do after learning how to turn off the sprinkler system. If you turn off the system manually, make sure to test and verify that other sprinklers remain functional.
