Could you try to run the pump after removing the filter grids and see what kind of pressure registers.

It should be very low if the return lines are clear (probably similar to your backwash/ waste line pressure).

I actually considered doing this when the pressure gets back up to 30 pounds again.

I also am going to get a new pressure gauge. Just in case....

Thanks again!
