One of the most common problems is a clogged nozzle. Other times the nozzle may be irreversibly damaged, so a new one is needed. If cleaning or replacing the nozzle doesn’t fix the problem, the next place to look is at the actual head. In these cases, your sprinklers might drip water instead of spraying it.

How long should sprinkler valves last?

One of the components that you may need to replace regularly are the wires, often due to improper installation and corrosion. Valves will give you 10 to 15 years of service, while controllers 5 to 10 years.

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.

Why would a sprinkler not work?

What are the problems with a sprinkler system?

Along with low heads, the most common problem found on sprinkler systems is tilted heads. Over time, sprinkler heads settle, tilt, and sink due to the natural compaction of soil, foot traffic, and lawn mowers running over them.

Does each sprinkler head have its own valve?

An irrigation system is typically divided into several zones, each of which feeds sprinkler heads in a different area of the lawn or garden, and each zone is controlled by a valve that receives signals from a centrally located controller.

What does a check valve do on a sprinkler head?

Check valves prevent this type of drainage from happening. Sprinkler head check valves also help to conserve the amount of water needed to fill the pipes each time the sprinklers begin running. By keeping the water in the pipes, the sprinklers will activate more quickly when they are scheduled to come on.

What is a valve in head sprinkler?

A valve-in-head (VIH) rotor is exactly what it sounds like: a rotor head that also includes a valve. This type of valve/emitter hybrid allows for a system that requires large volumes of water delivered with a high level of control.

What causes a sprinkler valve to stay open?

Air Trapped in the Valve: The valves may have air trapped in them. A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.

How do you find a hidden sprinkler head?

Use a shovel to gently scrape the dirt from the area to find each buried head. Use a metal detector to find buried sprinkler heads. Many valves have metal parts you can locate by running the metal detector over the surface of the ground. Valves are located directly under sprinkler heads.

What is the difference between a check valve and a backflow preventer?

A backflow preventer is to be used in high hazard situations and is meant to fully protect the potable water with their fail safe design while a check valve is used in low hazard situations and prevents backward water flow but it does not have the same fail safe components.

Where should a irrigation check valve be installed?
