Low pressure shut off

[Dadster1]

I am looking for ideas on a water pressure issue. I have a well with a whole house RO system. I am getting a lot of gas bubbles being drawn up the pump. So much so occasionally (once a week) the well pump pressure drops down to 3-5 psi and with the pump running, fails to get back to the 50 psi I need. When I notice the pressure drop, I shut the well down for 1 hour, turn it back on and I'm usually good for a week. My question is: If this happens when my RO is calling for water, it is not getting nearly enough, and I need a way to shut off the RO. I was hoping there is some type of switch out there that could detect when I lose water pressure and then shut down the 110 supplied to the RO. I have done small electrical jobs but I'm not familiar with anything available for this application. The RO has a low-pressure shutoff, but it hasn't worked in many years and the company was in Tiawan and out of business. Thanks for any help.

Low pressure shut off switches are available, but they must be manually reset. They look just like a well pump pressure switch, but have a reset arm. Available at a lot of hardwares and pump supply stores.

Like these.

Is this a jet pump? Unless you are running the well dry, you most likely have a rusted out jet if a deep well pump, or a hole in the suction line if a shallow well pump.

I think you need a well service company or a plumber familiar with wells to address this. You are sucking air somewhere.

No water with a submersible means the impellers are not floating. No water with a jet pump means the impeller seal is dry, with no cooling.

Past time to call for well service.
