Pressure won't change

I have two zones that the pressure from the pump/tank does not cycle from 40 to 60 PSI. It stays right at 42 PSI. I have a 1hp deep well pump and a 38 PSI tank. The other 7 zones cycle perfectly. This is a lawn irrigation system. both zones have about 7 heads in them. Please respone via the email address below also since I cannot monitor this site frequently.

In a good well-water sprinkler system, the flow in a zone is a perfect match for the output of the well, because too-rapid pump cycling is not good for the pump. In other words, the two zones you are worried about are the two zones you should not be worried about.
