The pump doesn't need replacing, just the valve cleaned or replaced. I had the same issue and eventually installed a ball valve in the output from the pump to the main water line. This prevents the city water from backflowing through the pump into the fresh water tank. We rarely use the fresh water tank, but if we need to I can easily open the ball valve from under the kitchen sink.
