I don't know anything about well systems. How do I know what the pressure settings are for my control box. It has no cover on it and I am clueless. I want to make sure my pressure tanks are set to the right setting for my control box.

This is a Square D control box. The usual settings are 20/40 or 30/50. This can be read on the cover. However, if the cover's missing you will have to look at the cut in and cut out point of the pump on the gage. NOTE: A open cover exposes live wires to the touch. This is a hazard and should be corrected. Good luck, Tom
