    This is my first experience with sprinkler systems.

    I am trying to install my electronic controller

    First, when the controller sends a signal to the valves (Orbit), is it normal to hear a big "TIC".

    Using the controller stations test feature, I have open the 3 valves I have. The run station of my controller (Rainbird) will not close them and now the only way to shut off the valve is to close the water. If I reopen the water then all the zones are activated.

    Please help

    Controllers often have relays, which will 'click'. The valves will also click when activated. Generally, barring a massive short circuit, a controller doe not hold valves open. If they fail to close, that is usually a mechanical problem in the valve: stuck solenoid, or stuck diaphragm. You can confirm this by unplugging the controller. If the valves stay open, it IS a valve problem.

    Thanks for the quick reply...

    I managed to close the valves by hand by unmounting them. Now, it is working fine. something wrong with the initial valve position maybe... I did also remove a rock from the valve....

    Ahhh, an important detail. You want to leave those on the outside of the valves.

    Any debris in a valve will cause a leak. Stuff as small as a grain of sand can cause a malfunction.

    Now then with your problem. Did you get all the valves to close and work properly every time?
