    I m looking for a switch to activate a 3/4 hp pump to keep a 1000 gal water tank full. So I need it to switch on when the water level
    Drops and switch off the pump when the tank is full. (the pump is outside the tank, drawing off of a shallow well). Would this be a good switch to use? Any others you think would work better? Thank you.

    Answer: 
    Open on rise means that the contacts in the float will open when the tank gets full, meaning you will shut the pump off when the tank gets full. The opposing terminology would be close on rise, which means your pump would turn on when the tank gets full. For your application, an open on rise will keep the tank full.

    I have 1.5 diameter hole, that I have to work with. The float diameter max has to be under 1". Water level is about 6 to 8 " below the flange.
    4" below the water level is an evaporator box. If the rod is to long I need to cut it. Do you have something that would work? !/4 0r 1/2 NPT would be fine.

    Answer: 
    According to the manufacturer, the float and stem are replaceable on this switch. Removing the top switch will change the operation of the entire switch and may not work as intended for your application. Please call us at 1-800-Grainger.
