Make sure the electrical wiring coming from the from the sprinkler valves is connected properly. If these are connected correctly then evaluation of the sprinkler valves may be necessary to ensure wiring is connected correctly. These are generally located outside of the residential home and near the water main. It may also be related to the water sensor, see troubleshooting issues related to "water sensor".

Sprinklers are not coming on.

Water sensor wiring ¶ 

If water sensor is disconnected then it will not disrupt the functionality of the ESP-6TM system and may help in troubleshooting by simply disconnecting. If wiring is properly connected continue.

Water sensor ¶ 

The water sensor is located on the exterior of the home. It needs to be cleaned per normal maintenance. Unscrew top and wash all parts including buoyant medium contained inside sensor with warm water. Before reassembly "it must" dry completely before reassembly. Follow user manual guidelines for care. If this does not resolve the issue then the sensor may need to be replaced.

Ensure the wiring at the valves is connected and free of corrosion. If not clean and reconnect. If the wiring is connected correctly then continue.

The valves may be from many manufacturers as they are not specifically related to the model ESP-6TM as this is the control box. It is best to check user manual to further evaluate the valves related to that particular system.

Rainbird timer: I have grass seed I want to water four times throughout the day. It is set to start at 5 am. The sprinklers turn on about two hours apart and thus there is no water from noon on. Any idea if this is fixable?
