What causes a sprinkler zone not to work?
A lawn sprinkler system is usually divided into two or more zones that water independently of each other. Each zone consists of several sprinkler heads controlled by a valve that is electrically activated. If a single zone is not working, the problem is usually an electrical issue or a defective controller or solenoid.

Head out to each valve and see if it is opened fully, broken, rusted, or stuck. Turn valves to the left to open them more. They should have been completely open already.
Why does one sprinkler zone have low water pressure?
Timer problems are the most common cause of intermittent low pressure in one sprinkler system zone.
