Water well pumps
 
Is there a switch or something that I can get to shut my pump off so that I don't have to go to my breaker box every time? I don't have a holding tank and I'm gonna use it for irrigation only

if it is 208V just break one leg with a heavy duty service switch,if you want to kill both legs and have protection a starter with overloads and stop/start push buttons

It's a 220v. Is there a control box I can get to where when I turn the hose on the pump starts and when I turn the hose off the pump shuts off by itself.

Install a pressure switch and expansion tank.

Yea I was hoping there was another way.

I wouldn't start and try reinventing the wheel at this point.

It's a cheap, easy, and very well tested solution. It's how every normal well pump installation works. There are other solutions (VFD's and PID controllers, for example), but they are not well suited to this kind of installation.

if the well pump holds anytype of pressure after shut down between the impeller and that shut off valve....a pressuretrol tapped into the pressured line will work.so when you open the valve the pressure drops and the pump runs.might have to break the power feed to the pump into 24Vs with a contactor and transformer to take that amp draw on starts...

Starting and stopping(short cycling), is a cause of early pump motor failure. Try to design your system to minimize starts.

My well pump wont turn on, I checked with a multimeter at the pressure switch. I have 239 volts on both sides of the switch. The weird part is the contacts remain closed with the power on and off. But no water. what could it be?

240 volts going to the pump and not water could be bad pump. Could be bad wires to the pump. Could be phantom voltage reading with digital meter.
