Troubleshooting
How often should my sprinklers come on?
Your ET Manager uses real-time weather information to
determine when watering is needed. Your sprinkler sys-
tem may water more frequently in the summer months,
and less frequently in the spring and fall months since
watering is now based on weather (which affects how
much water evaporates from your soil). Your ET
Manager automatically adjusts throughout the year to
keep the Moisture Levels in your soil reservoir at an
optimum level for the health of your plants.
Evaluate your landscape.
Before making any adjustments to the settings of either
your ET Manager or your automatic sprinkler con-
troller, make sure that the entire sprinkler system is in
good working order. It is important to be certain that
there are no broken sprinkler heads or broken pipes
affecting the performance of your system. Landscapes
and automated sprinkler systems are subject to imper-
fections that can be corrected. You may need to con-
tact your landscape installer or sprinkler profes-
sional.
1. Perform a walk through evaluation inspecting
your sprinkler system while each zone is run-
ning.
2. If problems in the sprinkler system are detect-
ed, please fix the problems or call sprinkler
professionals to assist you.
Are there dry or wet spots in your
landscape?
Dry and wet spots are often caused by problems with
your sprinkler system or the program in your sprinkler
controller. Spots within a station are areas where the
plant life is not uniform with the rest of the landscape
in the station, and these “spots” are either too dry or
too wet.
1. Check the sprinkler heads near the spot that is
dry or wet. It is possible that a broken head or
nozzle, or a clogged nozzle needs to be
replaced.
2. Check the layout of your sprinkler design.
Proper sprinkler designs should ensure head to
head coverage. Changing a nozzle size, adding
or moving a head may improve distribution
coverage.
3. If steps 1 and 2 do not solve the problem,
check the run times on your sprinkler con-
troller. Adding additional run time for the sta-
tion where the spot appears may compensate
for minor sprinkler system inefficiencies.
Note: Adjust the run time using small intervals of time.
Monitor the spots after an adjustment has been made.
This will help determine what run time is optimal to
prevent dry or wet spots.
Specific stations within the Valve Group
are too dry or too wet.
Stations are the distinct areas in your landscape
watered by one valve in Valve Group A or B. Dry or wet
stations are often caused by a run time problem pro-
grammed in your sprinkler controller.
1. Check the run time on your sprinkler controller
for this station. The dry or wet station can be
caused by too little or too much watering time
for that station.
2. Manually water the station if it is too dry to get
it the water it needs.
