check the line going to the pressure swithch. What happens is that rust and sediment build up in this pipe which is usually 1/4". it dont take much to clog it. When the tank is full and the switch cuts off you open a tap. The water comes out the ballast tank dropping the pressure. Because of the corrosion inside the line to the pressure switch the pressure stays up on the bottom of the switch which then slowly lets the pressure out (Like letting the air out a baloon slowly) and will reduce after the tank pressure has dropped. Then the pump will kick on and the pressure will build again. In a nutshell the corrosion is just not letting the pressure drop fast enough to keep up with the tank.

thanks for the info....now do i remove the switch to clean that properly

Yes. After you remove the switch install a new line if needed. In an emergancy you could clear the clog, but since the pipe is already been subjected to corrosion it will build back up quick. next there is about 6 phillips screws holding a plate onto the switch that the pipe fits into. remove these and rinse in clean water, then re assemble. Just in case some of the crud had gotten from the pipe into the switch base, this will remove it.

thanks usp45 it sounds strait forward but i'm just not sure about the 1/2 copper line feedind the switch,,,do I just eye the corrison after inspecting the pipe and cut it off according to what i think is needed

You need to remove it, then try blowing through it and see what happens.
