Loss of Pressure/Pumptrol Adjustment?

[bumblemer]

Hello--
I recently had my Pumptrol unit replaced--the pipe to it had filled with iron. It's set at 40/60. I have an 81 gallon tank, the pressure is at 38#. However, there is a small dip in pressure when I'm using water--previously it was steady. I know I can adjust the nuts on the Pumptrol--but which way should I adjust them to get rid of the pressure dip?
Thanks!

Read the top post in this forum, it will tell you all you need to know about pressure switches. You tighten to raise pressure, and loosen to reduce pressure but, you want a 20 psi differential between cut in and cut out settings. That is probably the "dip" you are talking about.
