Hi, Pam,

You should not run the pump for any long period of time 'til you get this figured out. Your pump should be off now.

Place the multi-port valve in "backwash" and turn the pump on. If the pressure does not exceed say around 30, let it run for at least two or three minutes, then shut it back off.

If the pressure exceeds 30 in "backwash", I'd shut it off right away.

Post back your findings and we'll go from there.
