Pump keeps running after it hits 50
I bought a new pressure gauge and 30/50 contact box but the pump keeps running when it hits 50. I can pull the contacts back and it will stay off till it drops to 30. I have an A.O. Smith 1hp. I did find a fried frog in the pump but doesn't look like any damage was done.

Maybe your Pump can only achieve a PSI of 49½ . . . . have you ever seen it go over 50 PSI
If you've tried everything else, I'd adjust the Cut-Out point down to 48, and then you'll know that's all you can get out of this Pump.

You need to check the line that connects the pressure switch to the system.
Usually it's a stub of 1/8" pipe and it gets rusted closed.

Then the issue lies with your pressure switch. It may not be set exactly to 50psi.
It may be a few psi over.
