Why do all my sprinkler zones come on at once?
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.
How does a zone indexing valve work?
Indexing valves allow an irrigation system to change zones. Easy to install and maintain, K-Rain’s patented hydraulic actuated indexing valve changes zones when the water flow is interrupted. These valves are ideal on pump applications, on site waste water disposal and reclaimed water systems.
How does a sprinkler indexing valve work?
An above ground indexing valve for sprinkler irrigation systems can control all zones, eliminating the need to dig into the ground to locate electric solenoid valve boxes. The indexing valve works either manually or fully automatic with a controller to turn the water supply on and off (pump or solenoid).
How does Fimco Hydro indexing valve work?
FIMCO Hydro Indexing Valves are preassembled with a sequencing cam depending on how many zones are on a particular sprinkler system. The cam can be easily removed and replaced by a different cam if sections are added or eliminated. The Hydro Indexing Valve must be cammed for the proper number of zones!
How do you know 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.
What causes a sprinkler valve to not shut off?
If your irrigation system does not turn off, you need to isolate the problem. This starts by checking the main water line and the controller. If those are working, then you need to locate the valves and check to see whether they are dirty, the diaphragm is torn, or the solenoid is broken.
How do you change a Fimco indexing valve?
Directions on how to replace your Fimco Stem and Disc Assembly: Loosen the coupling nut from the coupling. Unscrew the 6 or 8 screws around the perimeter of the valve. Remove off valve top Work the stem & disk assembly up into and out of the valve top until it disengages. Insert the new stem…
How do you install an index valve?
The Index Headset has three plugs:
- Plug the headset DisplayPort cord into your graphics card port (if you have a laptop you may need an adapter.
- Plug the headset USB cord into a USB 3.0 port on your computer.
- Using the headset power adapter, plug your headset into a power outlet.
What is a pump start relay?
The Pump Start Relay automatically synchronizes your pump for watering with your automatic sprinkler timer. It is compatible with 24-volt sprinkler systems and has a weather-resistant plastic case for outdoor installation.
Why are some sprinkler zones not working?
If just one zone isn’t working, the problem is usually an electrical issue or a defective controller or solenoid. To check the controller: Ensure the zone wires are firmly attached to the controller terminals, the transformer is plugged in, and the circuit breaker in the main panel is on.
How long do sprinkler zone valves last?
10 to 15 years
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.
Why does one of my sprinkler zones have no pressure?
Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone’s lines or a leak at a nozzle or two. Leaking nozzles won’t produce the same water pressure and need to be replaced, which is fairly simple.
Can a bad sprinkler valve cause low pressure?
One of the leading reasons for low sprinkler water pressure relates to the valves on your backflow preventer device. If you notice limited water pressure in your sprinkler system but normal water pressure inside your home, then the problem might be that your backflow preventer valves are not completely open.
How do I increase water pressure in my sprinkler zone?
Adjust the dial and deflector on impact sprinklers manually.
If you have a system with these sprinklers, try manually adjusting the heads to increase pressure. Every brand of sprinkler is different, but there’s typically a pressure valve on the top that you can turn manually to increase the pressure.
Why won’t my sprinkler valve open all the way?
Try manually opening the valve, using the on/off lever on top of the valve body. Some valves use a bleed screw to manually open them, so if you don’t see a lever labeled on/off or open/close, look for a screw, typically the screw has a knob handle to allow it to be twisted by hand. Do not fully remove a bleed screw!
What causes a sprinkler valve to stay on?
One of the most common reasons for a valve to keep running continuously is the accumulation of debris in the diaphragm, which prevents the valve from closing. This video will teach you how to clean the diaphragm on your valve. The most common reason for a valve to remain on, or weep, is debris.
How do you troubleshoot an irrigation valve?
Quote from the video:
Quote from Youtube video: 1 if a zone won't stop running it's all a certainly aim valve problem the kind of issue is something that would practically never be caused by controller. So in that case find and replace the valve.
