I have had no water going on 4 days now. My preasure when we try to fill the tank is only going up to about 10psi. Could our main line be frozen? Or leaking? Or are we out of water? Plaese help!

So you have a well, correct? If you have 10 psi in your tank you should get at least some water out of your faucets, do you?

Yes very little

We checked the main water line and it doesn't seem to be frozen either

Do you have a prv valve and has anything been worked on or changed

No nothing we have a low-pressure shut off gauge

Do you know how to bypass that shut off?

No

Then you will likely need a plumber, I think your switch may be bad but he can diagnois better on site than I can.
