    With a pressure switch you have constant pressure, no need to flip a switch. When you turn a valve on the water flows and when it gets down to a certain pressure the switch kicks the pump on, when it reaches the high pressure it kicks the pump off.

    None of this is rocket science, in fact it's old school.

    I get it, very simple. But now answer my very simple question how does the "valve" turn on unless he physcially walks to it?

    That's where the cheap controller and solenoid valves from Home Depot come in.
    There is not a simple solution to your situation.

    Instead of trying to invent stuff that doesn't exist, use the tools that are available. A tank and switch might be fifty bucks. A cheapass controller and valve might be thirty. A battery-powered programmable hose-bib valve would be more expensive, but simpler to install.

    Fair enough but your above comments all assume a pressure tank correct? So including the pressure tank, cheap controller and solenoid. Ballpark how much for those 3.

    Again I'm not trying to be combative, I'm simply try to ad hoc to what he already has in place.

    Cheap controllers and 30 amp power relays don't necessarily get along, so the idea of trying to have a "programmable relay" may not be so simple.

    If you don't have a hundred bucks or so for this, knock off a liquor store :gunsfirin

    I wouldn't say without looking at it. You must also consider your climate, it must be winterized properly.

    Ok I'm listening your programable bib valve comment didnt come up until the last few posts :nono:

    So if I follow correctly put a battery-powered programmable hose-bib valve on the line that supplies the sprinklers, bib valve opens based on my schedule, this sends a call to the pump which has a pressure tank :clapping: bang I have my automated watering? Is this correct?

    Or I use the solenoid valve with cheap controller (controller gets me my automation) Contoller opens the solenoid valve which engages the pressure tank bang I have my automation

    Yes?

    The pump system is self contained. It has no connection to any controller. It has power 24/7 from the receptacle it's plugged into.

    When water flows from the pump system, the pressure switch will react to the drop in pressure, and turn on the pump. When the flow stops, the increase in pressure will turn off the pump.

    Note that I did not state what causes the water to flow from the pump system. It doesn't matter what initiates the flow. That is up to you.
