My water started surging in the house so I replaced the pressure tank. In doing so I took it from right beside the pressure switch and placed it 200 feet away. When the problem continued with the water surging I replaced the pressure switch. The problem continues.

I have checked the pump, replaced the pressure tank, replaced the pressure switch, but still the water surges and the pressure switch clicks off and on.

I can't figure out what is causing it.

We had a post about this type of problem several months ago. The problem was resolved by moving the switch to within a few feet of the tank, which is typically where they are placed. Even closer, in fact. In your case, you would simply put the tank back in its original location next to the switch.
