I have a cottage system that runs a jet pump to draw water form the lake. I have the pressure switch set at 40/60. I have a Vitapur whole house filter in the system. My setup is pump to pressure tank to filter to mainline. I am getting low pressure even though my filters have been replaced. I was wondering if it might be better to install the filter between the pump and the pressure tank, rather than between the tank and the main line. My theory being that the power of pump could force the water through the filter better than the pressure from the tank and then once it is in the pressure tank, it would have uninhibited flow into the main line. Thoughts?
