    Searching the internet for help because of my lack of knowledge I stumbled upon this site. Seems like the knowledge needed is certainly here.
    There is a long backstory here but I'll try to keep this short.

    I installed an irrigation system and 500 gal. holding tank that is
    fed from my 5 GPM well. The holding tank is enough to water what we need (backyard) but
    it only refills when the house holding tank empties during normal use. This
    leads to being out of water for 1 1/2 to 2 hours at random times while the 500 gal tank
    refills. We have a pump control switch installed to start the pump in the
    500 gal tank. I am hoping there is a way to install a float type switch in
    the 500 gal tank and have it start the well pumping water when the level
    goes down. Then we could irrigate at night and not be without water for long
    periods. There is a float valve in the tank which shuts off water when it is
    full.
    What I need to know is what equipment I need to install be able to control when the well fills the 500 gal. holding tank. I'm a complete rookie at this. That's why I didn't get it right when I initially installed everything and am trying to retro fix it.I've read a lot of posts here but haven't been able to get an exact answer.

    I attached a "line" drawing to hopefully make things clearer.

    The float switch should be the only control needed for the well pump. Put the pressure tank and pressure switch on the booster pump in the cistern and let it run the irrigation AND the house from the cistern. Like this.

    Or you can use a pressure tank control on both pumps and have the option of running the house directly from the well pump OR from the cistern booster pump. Like this.

    Thanks for the reply Cary. As I stated, I'm a rookie at this stuff. Always been a DIY type of guy but I've decided at this stage in life there is more to this than I care to learn. Called a local pump expert to see what his opinion is. I'll probably have more Q's once I speak with him. All I really want to know is how to add the float switch, control it and specifically where and how it is connected to my existing controls. Stay tuned, I'll be back....

    This drawing has a wiring diagram for a float switch and Cycle Sensor, which is pretty important with a 4 GPM well.
