Back to Questions

Why won't the valve shut down?
To determine what is causing the valve not to shut down  properly, follow the steps listed below:    
  1. Disconnect one of the valve wires.  Does the valve shut off?
  • Yes,  the valve shuts off, the problem is with the timer. (Please refer to the timer section in your Owner's Manual for details.) 
  • No, the valve does not shut off, check the bleed screw to make sure it is not loose or broken.
    2.  Is this a new installation?
  • Yes, low flow may prevent the valve from closing, compare the GPM (gallons per minute)/LPM (litres per minute) requirements of zone to valve specifications. 
  • If the GPM/LPM is not within the specifications, add more heads to increase water flow or select a valve that works well at low flow rates.
  • No, turn off the main water supply
  • Remove valve cover and diaphragm. 
  • Turn water back on and flush out for 15 seconds. 
  • Inspect diaphragm for holes/tears replace if necessary.

Back to Questions

How do I design my sprinkler system?
Before you start:
  • Check local codes and permits by calling your local water company or the proper municipal for information on building codes or permits required for the installation of underground sprinkler systems.They can also tell you about local codes for the backflow prevention required to protect your water supply from contamination, as well as advise on where to locate the backflow device in the system.

  • Check with your local utility companies before you dig to identify any buried cables or natural gas lines.

  • During installation, you will need several accessories and a variety of pipe fittings. Other materials you may need during installation include:

    • PVC pipe cutter
    • Screwdriver
    • Pipe wrenches
    • Hammer
    • Trenching shovel
    • Line marking paint
    • 1" pipe clamps (poly only)
    • Teflon tape
    • Tape measure
    • Solvent, primer, rags (PVC only -- do not use pipe dope on plastic-threaded fittings.)
    • Toro flow and pressure gauge
    • Marking flags
    • Grease caps

How do I adjust the rotor?
For step-by-step procedures on adjusting the sprinkler arc, distance or radius consult your Owner's Manual or view our interactive product manual online by selecting the rotor you currently own below:


Troubleshooting:


1. No water spray from the sprinkler nozzle, but the head pops up.
  • The radius adjusting screw maybe improperly set. - Turn the screw counterclockwise.
  • There maybe debris in the nozzle - Remove any debris.
  • The internal nozzle screen maybe plugged with debris. - Clean the screen.

2. Water sprays out of the cap or body of the sprinkler head.
  • The sprinkler is damaged or defective. - Replace the sprinkler head.

3. A sprinkler rotates in one direction and then stops.
  • There maybe not enough water pressure. - Increase the water pressure.
  • Valve flow control may not be open enough.
  • Water pressure to home is lower than in the past (New development in the area).
  • Pipe maybe crushed.
  • Pipe maybe broken (leaks result in lower water pressure).
  • The sprinkler head maybe damaged or defective. - Replace the sprinkler head.

Back to Questions

What does the PVB (pressure vacuum breaker) do?
Installed above ground, pressure vacuum breakers (PVB's) provide single-point backflow prevention for an entire sprinkler system. They are designed to keep the water supply clean and typically are used with in-line or angle valves.

Back to Questions

How do I program my timer?
For complete step-by-step instructions on how to program your controller, consult your Owner's Manual or view Toro's interactive manual online by selecting your controller below:


General Programming Guidelines:
  1. Set the current time and day of the week - Without this information, the controller/programmer will not perform the required functions.

  2. Set Run Times - Run times are assigned to programs and tell the controller how long to run each zone. As a general rule, Toro recommends a run time of 5-10 minutes for fixed spray sprinklers and 30 minutes for rotary sprinklers.

  3. Set Start Times - Start times tell when to start each program. The controller will run each zone sequentially, one after another, based on the run times selected. When one zone is finished, the next one will start. If you want the same series of valves to run more than once in the same 24 hour period, you must assign a second start time to that program. Remember a second start time does not start the next zone, it starts the same cycle over again.

  4. Set Active Days - Depending on the controller being programmed, there are three ways to set the active days. Some controllers offer all three methods (Odd/Even, Interval and Calendar), while others only offer only one or two.
As noted above, every controller is different and will offer different features. To program those additional features, refer to your Owner's Manual. Examples of these types of features include:

  • Season Adjust - Allows user to make adjustments to the watering schedule by program instead of zone by zone. This is a big time saver.

  • Rain Delay - With this feature, the user can set a 1 to 7 day watering delay. At the end of the programmed delay, the controller will resume normal operation.

  • Non-Volatile Memory - In the event of a power failure, the controller will remember the set program even without an installed battery.

Back to Questions

Why doesn't the timer work on the manual cycle?
  • Check the display, if you see a raindrop it is not the controller. It is the rain switch telling the controller don't water.
  • If the raindrop is not there, check the wiring with the volt meter to see if there is a break in the wiring from the controller to the valve.
  • No power to the controller.
  • No programs currently on the controller.
  • Re-verify manual start procedures from your Owner's Manual.

Back to Questions

Timer is constantly blowing fuses?
What to do when the controller blows a fuse:
  • Disconnect transformer.
  • Disconnect common wire.
  • Replace blown fuses with a new one.
  • Plug transformer back in.
  • Run a manual start program through every zone.
  • If the fuse blows, it is a bad controller.

If the fuse does not blow:
  • Disconnect transformer.
  • Reconnect common wire.
  • Plug transformer back in.
  • Do another manual start program going through each zone until the fuse blows.
  • Whatever zone the fuse blows on has either a short in the wiring or a bad solenoid.

How do I get software updates for my ECxtra Scheuling Advisor program?
Note: To check for updates, you must have an active internet connection.

  1. From the main menu of the software program, click on the “About” tab located at the upper right side of your screen.

  2. Software version information will be displayed along with a “Check for Updates” button and a “License” button at the bottom of the page.  Click on the “Check for Updates” button.

  3. The program will check for new updates and display a message if the version you are running is outdated.  If you do not have the current version, you can install the newest version by selecting the “Next” button located at the bottom of the screen.

Back to Questions

How do I increase or decrease the amount of water the ECxtra Scheduling Advisor is applying by zone?
  • While in the Automatic mode, click the Zone Setup Stepping-Stone. 

 

  • Click on the zone description then adjust the runtimes using Runtime Override %. 

  • You can also go to View Schedule and make adjustments for each zone using the "+" or "–" sign.

 

Tip: The scheduling Advisor assumes you have uniform soil like loam. For tight soils like clay, you may need to reduce the runtime by as much as 50%. For sandy soils, you may need to increase the run time an additional 10%.

Tip: Conduct a runoff test.  Run each zone until you see puddles occurring and record how long it takes.  Compare that time with the Scheduling Advisor's recommendation.  Reduce the runtime(s) if necessary.

Back to Questions

I want to adjust the Ecxtra schedule for changes in the prevailing weather.
While in the automatic mode, click the Weather Setup Stepping-Stone, then use Update to change the average high temperature, humidity and wind for the new weather conditions.

Back to Questions

How do I make changes in the ECxtra Scheduler for the time of day that my sprinkler system waters?
When in the automatic mode, click the View Schedule Stepping-Stone, then adjust the Start Time(s) and Runtime(s) if needed using the + or – keys.

When in the manual mode, click on the Zone Setup Stepping-Stone and select the zone you want to adjust.  In the Start Times/Watering Days window, fill in the start times you want in the spaces provided.


Tip: Water before dawn or early in the morning when evaporation losses are minimal. Do not water at midday – evaporation is at its peak.

Back to Questions

How do I keep my Ecxtra timer from watering during a rainfall?
A Toro rain sensor can be added to control the system during a rainfall.

Back to Questions

Why won't my sprinkler rotate?
Was compressed air used at the end of last season to purge your system of water?

Water lubricates the gears in rotors (MultiStream or SingleStream). When you use compressed air to clear the system you will run the gears dry. If any sprinkler head is run dry for more than two minutes or at a pressure greater than 40 psi you may have damage to the head.
  • Replace the damaged sprinkler head.
  • Use proper winterization procedures in the future. We recommend that winterization be done by a professional. In addition to winterizing the system, many will start the system in the spring and cover any damage they may have caused.

Back to Questions

Why do all or some heads fail to rotate or rotate reliably on my new system?
SingleStreams are designed to operate at 25-75 psi. The nozzle controls the amount of water flowing through the head. The smaller the pattern, the lower the flow rate. The lower the flow rate the more sensitive the sprinkler head is to having the proper pressure. A full circle head may work at low psi but as you reduce the pattern size you will more likely experience problems.
  • Remove one of the heads that does not rotate and replace it with a pipe coming up 12 inches or more.
  • On top of the pipe install a fitting with one port pointing up and one to the side.
  • Reinstall the same head you removed on top of the tee and install a pressure gage on the side.
  • Run the zone and observe the pressure.
  • If the pressure is less than 25 psi, the problem is not the head. Other possibilities could be a crushed pipe or other flow restriction.
  • If the valves have flow control, make sure its open all the way.
  • You maybe able to use a smaller nozzle, which will raise the pressure.
  • Longer run time will be needed to compensate for reduced GPM (gallons per minute).
MultiStreams are designed to operate at 30-50 psi. The pattern disc controls the pattern and restricts the amount of water flowing through the head. The smaller the pattern, the lower the flow rate. The lower the flow rate the more sensitive the head is to having the proper pressure. A full circle head may work at less than 30 psi but as you reduce the pattern size you will more likely experience problems Check the pressure at the head to determine what is causing the problem.
  • Remove one of the heads that does not rotate and replace it with a pipe coming up 12 inches/30.48 centimeters or more.
  • On top of the pipe install a "T" fitting with one port pointing up and one to the side.
  • Reinstall the same head you removed on top of the tee and install a pressure gage on the side.
  • Run the zone and observe the pressure.
  • If the pressure is less than 30 psi, the problem is not the head. Other possibilities could be a crushed pipe or other flow restriction.
  • If the pressure is greater than 30 psi, replace the head.

Back to Questions

Why are the rotor heads rotating slower than they did in the past?
It could be that the filter screen to the sprinkler is partially blocked.
  • Remove cap and lift internal parts out of the body.
  • Rinse parts in a pail of clean water. (Filter is on the bottom of the part that was lifted out).

Is there any new construction in the area since the system was installed? 

If yes, this may decrease the available pressure to the system than when it was first installed.
  • Perform a flow test to see what the water supply is capable of currently and modify the system accordingly.
  • Install a booster pump which is less labor intensive (but more expensive) option.  Contact an irrigation professional to see if a booster pump will help and for assistance in choosing the correct one.
  • Reduce the number of heads per zone.
  • Replace the existing rotors with smaller nozzles (Toro SingleStream only).

Back to Questions

Why won't the valve turn off?
To determine what is causing the valve not to shut down  properly, follow the steps listed below:    
  1. Disconnect one of the valve wires.  Does the valve shut off?
  • Yes,  the valve shuts off, the problem is with the timer. (Please refer to the timer section in your Owner's Manual for details.) 
  • No, the valve does not shut off, check the bleed screw to make sure it is not loose or broken.
    2.  Is this a new installation?
  • Yes, low flow may prevent the valve from closing, compare the GPM (gallons per minute)/LPM (litres per minute) requirements of zone to valve specifications. 
  • If the GPM/LPM is not within the specifications, add more heads to increase water flow or select a valve that works well at low flow rates.
  • No, turn off the main water supply
  • Remove valve cover and diaphragm. 
  • Turn water back on and flush out for 15 seconds. 
  • Inspect diaphragm for holes/tears replace if necessary.

Back to Questions

Why is the valve leaking?
** Make sure the water supply is shut off to the irrigation system prior to disassembling any portion of the valve to avoid injury.

If water leaks to the sprinkler heads, check the following:

  • Disconnect one of the wires at the valve. If this stops the leak the problem is not the valve. If the leak does not stop determine if the leak is internal or external.
  • Verify if Manual option is on - If yes, turn it to the off position.
  • Check valve diaphragm for a tear, pinhole or scratch. - Replace diaphragm.
  • Verify if the solenoid is stuck - The plunger inside the solenoid could be stuck. If it is stuck clean or replace solenoid.
  • Is debris visible - Clean out valve.
  • Internal crack - Replace valve

If water leaks to the valve box, check the following:

  • Check bleed screw. Is it closed? - The black or white flow control screw maybe loose or broken.
  • Is the Bonnet (top of the valve) tight? - Screws on the top of the cover assembly may need to be tightened.
  • If an external crack is present - Replace valve.

For further instructions or illustrations on your particular valve please refer to your Owner's Manual.

Back to Questions

Why is the valve vibrating or buzzing?
First you need to determine whether it is the valve or the controller. To do this take one valve that isn't working and connect it to a station on the timer that is working. If it works then we know it is a problem with the controller. If it does not work the problem is with the valve.

** Make sure the water supply is shut off to the irrigation system prior to disassembling any portion of the valve to avoid injury.
  • There maybe excessive water running through the valve. To determine use a water gauge to check the water pressure.
  • The plunger or the solenoid maybe damaged. To verify attach solenoid to a working valve. If the valve continues to it is not the solenoid.
  • Some humming and vibrating is normal - there maybe nothing wrong.

Back to Questions

Why is the PVB (pressure vacuum breaker) leaking?
If you are experiencing a backflow condition, it could be that the pressure is dropping below 25 psi. If this is the case, do one of the following:

  • If the zone valve are equipped with a flow control handle: Open only enough for the zone to function properly.

  • If the valve does not have a flow control handle: Go to the pressure vacuum breaker (PVB) and open the outlet (top one) side only enough for the zone to function properly.

To operate/troubleshoot:

  • Close outlet (upper handle).
  • Close inlet (bottom handle).
  • Slam open inlet. Note: Opening the inlet fast as you can will result in the internal float sealing the vent. Opening it slowly may result in the float not sealing the vent and lots of water purging from the vent area around the top of the PVB. Some water leakage is normal when opening the valve, but it normally stops within a few seconds.
  • Open outlet just enough to hear water flowing. When the water stops, open it all the way.
