Why do 2 sprinkler zones come on at once?

5. Water is coming out of multiple zones at the same time: For the valves to stay open in one zone, while shutting outlets in other zones, there needs to be a minimum amount of water pushed through the valve.

Can you run two sprinkler zones at the same time?

Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.

Why are two of my sprinkler zones not working?

Failing zones may also be caused by an electrical problem, which can manifest as a problem with the timer, the valve, the solenoid, or the wire. Frequently, a bad connection may be responsible. When you suspect that the problem may be electrical, checking the timer is typically a good place to start.

Can you have different types of sprinkler heads on same zone?

While you can mix different brands in the same zone, don’t mix the type of head because they have different flow rates. Rotor heads, spray heads, matched precipitation etc all throw water at a different rate.

What happens if a sprinkler solenoid goes bad?

If your solenoid is bad, the water pressure in the sprinkler chamber will not be changed and the valve will fail to open. Turn off the water supply. Open the solenoid housing and inspect the plunger. Reinsert the solenoid plunger into the housing.

How do you know if a sprinkler valve is bad?

Signs of issues in sprinkler valve:

Water not turning Off: If you notice that water is not closing off from the sprinkler, then there seems to be an issue in the diaphragm valve.
Leaks of water:
Broken Sprinkler Head.
Stuck Valve.
Wiring:
Irregular Watering:

How many zones can a sprinkler valve control?

They can be 2-7 zone configurations. All irrigation zones get glued to it and and one pipe is the water source.

Is there a valve for every sprinkler zone?

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. Often the valves are located inside one or more in-ground valve boxes.

Why won’t my sprinkler zones turn on?

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.

How Far Should sprinklers be from the house?

Make sure sprinklers don’t spray your house, especially the windows, or over window wells. Keep the spray at least 2 feet away from the house.

How can you tell if a sprinkler solenoid is bad?

Signs You Have a Problem

The Water Won’t Shut Off. If you have this problem, it’s very likely the solenoid.
Low or Uneven Water Pressure. The solenoid controls the water pressure.
Water Leaks. There are many points in a sprinkler system that can leak.
Current Testing.
Valve Inspection.
Parts Replacement.

How do you know when a sprinkler solenoid is bad?

Signs that Your Sprinkler Valve Solenoid is Bad Water leaks: High pressure from a broken solenoid can put a lot of stress on your sprinkler system and burst small or large leaks throughout it. Low water pressure: Low water pressure can be just as much of a problem.

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.

Do you need a valve for each zone?

Use a single circulator pump, plus one valve for each zone. The boiler and pump runs whenever any zone is calling for heat, but the valve controller only opens the relevant valves to allow water to flow to the calling zone(s). Use a pump for each zone.
