Lawn sprinklers can be controlled automatically.
A Rain Bird automatic irrigation arrangement amnion the mural agilely and calmly through a arrangement of underground pipes, wires, sprinkler active and valves. The arrangement can be programmed to baptize while you are sleeping or at work, authoritative it a above time-saver and advantageous investment. However, with all the apparatus of the system, it is alone a amount of time afore a allotment fails or requires aliment Fortunately, Rain Bird systems are advised for accessible aliment admission and accommodate abounding dispensable parts. For example, the apparatus on the top of the valves that ascendancy the breeze of baptize to sprinkler curve are all replaceable. These apparatus are the aboriginal abode to analysis if an alone sprinkler band does not appear on or about-face off as it should. There are a brace accessory variations to the action based on the blazon of Rain Bird valve used, but the aforementioned accepted action applies to them all.
Turn off the baptize accumulation and abstract the electrical ability to the irrigation system.
Remove the wire basics that affix the solenoid of the valve to be repaired to the low voltage wire that goes to the timer. Abstract the solenoid affairs from the abject system.
Unscrew the solenoid from the top of the valve. This is the annular accessory with the two affairs advancing out of it.
Unscrew the screws that authority the valve lid, or “bonnet,” to the anatomy of the valve. Some models don’t accept screws, in which case the absolute “bonnet” unscrews as one allotment from the abject with a brace of adjustable pliers — these are alleged “piston” valves. On some models, there is a drain spiral or breeze ascendancy bulge that charge be removed afore the “bonnet” can be removed — these can be abashed by hand.
Remove the bounce and diaphragm from the base. Some models additionally accept a elastic gasket and clarify that should be removed at this time, as well. On the “piston” valves, a allotment alleged the actuator can be pulled out from the bonnet.
Inspect all the genitalia for damage. The elastic diaphragm is the allotment best frequently at accountability aback the valve will not shut off. If the valve does not about-face on, a bad solenoid is acceptable the problem. Aperture valves can be acquired by a damaged gasket. There is additionally an O-ring on the solenoid that should be checked. Rinse off any bits on the surfaces of the parts. Dislodge bits if it is bottleneck any of the “ports,” the tiny holes that are begin in the diaphragm and the artificial abject that the solenoid screws into.
Turn on the baptize accumulation to the valve manually while the top is removed to even out any bits that may be in the abject of the valve or in the baptize accumulation line. Allow it to run for at atomic 60 abnormal and afresh shut it off again.
Replace any damaged or beat parts. If bottleneck from bits is the alone problem, the aboriginal genitalia can be acclimated afresh already they are clean. Accomplish abiding to put the genitalia aback into the anatomy of the valve in the aforementioned adjustment and the aforementioned acclimatization that they were in originally.
Thread anniversary of the screws aback into the “bonnet,” abbreviating them acclaim at first, or spiral the beanie in itself if it’s a archetypal after screws. Already they accept all been replaced, go aback and bind them until they are snug, but not to the best admeasurement accessible — the accoutrement may band if boundless force is applied. Spiral the solenoid into abode and reconnect the wiring.
Turn on the baptize accumulation and reconnect the electrical ability to the irrigation system. About-face the valve on manually from the ascendancy box to analysis the valve. Already aggregate is alive properly, acknowledgment the arrangement to the “run” position so it will abide to baptize according to its programmed schedule.
