You need to expand your search - common places for leaks are where the water pipes have junctions - outside shower and faucet fittings would also be high on my list. Once you rule those out then focus on the pump. Leak might be very tiny and it may not be obvious.
This gets back to my original question: How do I gain access to those hidden areas where a leak may exist? There are no access doors that I can see to check beneath the kitchen and bath sinks, toilet, outside shower, water heater plumbing.
