Thank you for purchasing the WaterGreat LLC SR-2 gravity feed watering controller.
1) Attach stake and stainless steel tube to the control assembly as shown and place in
the ground where the sun shines
at least 5 hours a day. Turn knob
to below “1” for no watering (as
shown in picture) until the unit
charges in the sun (up to 24
hours).
2) Place the slender sensor rod in
an area watered by the system,
about 4 inches from a dripper if
using drip irrigation. Push the rod
into the soil, red dot UP at a slight
angle, so that lower tip is about 1
1/2 inches from the surface. Use
undisturbed soil. It is best to
place the sensor in an area that
dries the quickest. GIVE THE
AREA A GOOD WATERING
AFTER INSERTION.
3) Connect the motorized gate valve
to a spigot or hose as shown.
Alternately, you may remove the
hose fittings and directly plumb to
1/2” NPT (gives maximum flow).
Connect the outlet to the drip
irrigation system or other watering
system. Gravity feed systems need
special care to ensure even
watering. Use big tubing and low
flow dripping if irrigating more than a
couple of plants. Use adjustable
drippers and make each dripper
output the same quantity of water. If
only watering one or two plants,
direct water so that each is watered
equally. See the section on
“Watering considerations for Gravity Feed Systems.” If desired, the valve can be directly
installed into PVC pipe or plumbing as well. Note the IN and OUT can be either side. If
sand or debris is present in the water, place a filter in-line prior to the valve.
