I have an irritrol garden sprinkler system. I just went to turn the
Sprinklers on from the Controller and although it shows the different
cycles when i turned it on manually there is no water coming out of
the sprinkler heads. I have checked and made sure that the water is
not turned off.
Let me know where to begin.
First thing I'd check is if it has a rain sensor or similar lockout.
If so, is it set to bypass? After that, I'd try removing power
completely and resetting it. Next, I'd start with one zone. Set it
on and check to see if you have voltage going to the terminals for
that zone. If not, disconnect the wires to the zone and see if you
then have voltage to the two terminals. If there is no voltage, then
it's the controller. If there is then it's time to find out where
the valve for that zone is and what's going on out there. Most
valves you can also turn on manually by turning them.

I disconnected the rain sensor completely and had no luck. Everything
was reset etc etc. I did check the main power and it did read 24VAC
in the controller. I have seven zones so what i did was i
disconnected the wire to zone 1 and then turned the sprinkler on and
saw on the display it reporting zone 1 active. I connected one probe
from the voltmeter to the single wire zone 1 and the other proble to
a electrical ground cable (did i do this right) and read voltage
across. So this tells me it is not the controller. I guess i will
have to find the valve for the zone. Are all the valves in one
place. Is it where the pressure regulator is i.e near the sprinkler
shut off. Sorry, doing my best have no knowlegde of sprinklers.
You get no water at all, is this first time on and no water this year,
if so maybe the water is off, I have a basement and exterior shutoffs.
All my valves have their own wiring on the valve at each zone all over
the yard, can you find a valve to see if its got power, and maybe just
a water valve somewhere is off, I remove an exterior anti drainback
valve each fall, and have shutoffs cobbled in besides a basement main
or also referred to as RTFM
Other suggestions / comments that you'll probably get are:
Is Google broken? or DAGS (do a Google search)
Do you have the manual for your irritrol sprinkler controller?
(btw it's helpful to post the model number of the unit you are asking
about. Irritrol makes a number of controllers)
Manuals usually have a troubleshooting section.
If you don't have the manual, then go to their website, unless the
controller is ancient there will most likely be info online that will

Based on what I have read so far my best guess is a broken common wire. I
have made certain assumptions here so let me explain. My first assumption
is that you have multiple zones and none of them are coming on. If it is
just a single zone on your system then the diagnosis broadens to the
common wire, the hot wire, or the valve itself. My second assumption is
that when you disconnected the rain sensor, you a) reconnected the common
wire to the common terminal or b) put a jumper between the two sensor
terminals, depending on how the sensor is connected into the controller.
My third assumption is that you actually have the 24vac signal at the
proper terminals when you activated zone 1. You should be reading from the
#1 zone terminal and the Common terminal identified as COMMON, COM, C, or
VC depending on the model controller you have. You said you have verified
that your water is turned on but the best way to verify that is to find
your zone valves (typically found in rectangular boxes with green lids)
and activate a valve using the manual bleed function of the valve
(typically a screw, or lever, or sometimes you just rotate the solenoid a
quarter turn). This will turn that valve on until de-activated. My final
assumption is that you have NOT been digging anywhere recently and
possible put a shovel through your wires (if so thats where you look).
Given all that, your likely source of aggravation is the common wire going
from the controller to the first valve or valve grouping. This is a shared
wire that gets daisy-chained from valve to valve. If you can locate the
first physical location where this wire terminates it is likely that wire
connection. Please feel free to contact our Technical Support department @
(800) 634-TURF (8873) for further clarification or assistance.
Check its got power in, power when switch is turned on. I can hear my
clock and feel the unit locking in when manualy switched, does it have
a different Day lockout, turn the days rotor, loose panel wires, if
not the panel then a rain sensor or main valve maybe. On my panel Ive
had switches stick, setting lockouts, loose wall plug, loose wires,
fuse popped. Outside just cut cables from the gardener.
The controller is coming on and i do see it cycling thru the zones.
Only thing is there is no water coming out at the zone.There are no
lose plugs or wires. Nothing should be cut as there is no gardener
doing my lawn. Also, i have not cut the lawn in a couple of months.

One of the first responses was, I think, to replace the battery, but it
was phrased ineptly and might not have been understood. Every ten years
or so I have problems with my controller (another brand) and each time
replacing the battery solved the problem.
Since this is a multi-zone system and apparently none of the zones is
working, the water supply and the controller are the likely problems.
Seven valves are very unlikely to fail all at the same time, as are
seven sets of wires.
I think they sometimes behave kind of like a browser that hangs and you
can't do anything but reboot....the key, I think, was to cut all power
for long enough time that whatever glitch was in the memory disappeared.
Changing the battery alone did not solve it; had to cut the AC as well.
I got it to work, In the controller there was a lose connection on one
of the wires that were crimped together. I happen to wiggle the wires
and the sprinklers turned on. I did go back and secure and dress all
the connections. Everything seems to be good now. Thanks all for
