I have a variable speed constant pressure system with check valves, transducer, and pressure tank after the discharge of the pumps. My problem demand for water has ceased and the pumps turn off my pressure immediately falls 2 PSI which causes the system to come back on again. This results in constant cycling. I have increased my on/off band to prevent the cycling but when the pumps turn off and the pressure is trapped shouldn't it remain constant and not drop 2 PSI?
What could be causing the 2 PSI drop?
I don't think it's a leaky valve because then the pressure would continue to fall more than 2PSI.
