Whisper King question.
Wondering if this water pump is adjustable? If so where is the adjustment screw?

You can adjust the pump shut-off psi setting........
On the end of pump head in center is an adjustment screw.
Looking at pump head
Turn screw clockwise to increase
Turn screw counter clockwise to decrease
Turn only 1/2 turn at a time then check
Turn no more than 1 1/2 times total or you can damage pressure switch
