What does an automatic sprinkler system detect?

Sprinklers systems consist of the network of piping, water supply, sprinkler heads, and alarm and detection devices that sense the heat from a fire and automatically distribute water to completely extinguish the fire or control its growth.

What is a zone in a sprinkler system?

installing a home irrigation system All systems, however, are divided into areas called zones; each zone is designed to water separate areas with very specific types of sprinkler heads. In this type of zone, the angles of the sprinkler heads are specifically placed to hit just one area and avoid overspray.

Why does one sprinkler zone not work?

A lawn sprinkler system is usually divided into two or more zones that water independently of each other. Each zone consists of several sprinkler heads controlled by a valve that is electrically activated. If a single zone is not working, the problem is usually an electrical issue or a defective controller or solenoid.

Do sprinkler systems have to be monitored?

Monitoring is not required for automatic sprinkler systems protecting one-and two-family dwellings. Monitoring is also not required for trim valves to pressure switches in dry pipe, pre-action, or deluge sprinkler systems provided they are sealed or locked in the open position.

How does an automatic sprinkler system work?

Automatic Sprinkler Systems: How Do They Work? An electrical controller is attached to a set of valves buried in a box in the ground. The primary water source is directed towards the box and separated into various zones. Each of these zones can be controlled by a valve set to release each one separately.

How many impact sprinklers can you have on one line?

If all your sprinklers flow rates are 1GPM you can add 3 of them on the same line to run simultaneously. If you need more sprinklers you can set them up on a separate hose and run them at a different time, essentially creating sprinkler zones.

Why does my sprinkler system only work in one zone?

Just like leaks, clogs may also affect only one zone in your sprinkler system. Debris that has worked its way into the nozzles is one cause of a clog. Or, you may have a clog created by a broken valve, that is remaining closed when it should open to allow water through. Cleaning out the debris in the sprinkler is typically simple.

How do you turn on a sprinkler system?

You’re actually manually turning on the zone by twisting the solenoid open. If, by manually turning on the zone your sprinkler heads pop up and start the irrigation, you have successfully verified that there is water pressure to the whole system and can check that off of your list as a potential cause for the problem.

What to do if your irrigation zone won’t turn off?

Replacing an Irrigation Valve Diaphragm If only one zone is malfunctioning in your sprinkler system, it’s likely caused by a valve in that particular zone. More specifically, it may be an issue with the zone control valve. Use an external bleed screw to dislodge any dirt or debris that may be stuck in the diaphragm of the valve.

What to do if your sprinkler system is low pressure?

Make sure that the zones of your sprinkler system are working one at a time to make sure there is no splitting of water pressure that allocated for one valve. Turning off one of the zones that are working, will correct your problem in no time. 2. Clogging Situation It is normal to have things be stuck along the tubes of our sprinkler systems.

Where are the zones located on a sprinkler system?

Each zone valve is piped to a set of sprin- klers. When the valve is turned on, either by hand or in response to an electronic signal from the controller, all the sprinklers piped to that particular valve go on. In most cases, there are several valves located together (called a manifold). These are often in a valve box if underground.

Why is one zone of my sprinkler not turning off?

If only one zone is malfunctioning in your sprinkler system, it’s likely caused by a valve in that particular zone. More specifically, it may be an issue with the zone control valve. Use an external bleed screw to dislodge any dirt or debris that may be stuck in the diaphragm of the valve.

What happens when a zone valve is opened on an irrigation system?

When a zone valve opens, water flows through underground plastic tubing to feed sprinkler heads that pop up and distribute water to the lawn and landscape for however long the controller allows the zone valve to remain open. Problems with an irrigation system typically make themselves evident with several common symptoms:
