Our pump runs every 3 hours. The pump's pressure guage takes three hours to drop to a level that causes the pump to run.

We've closed the values that go from the pump to the house and outside faucet. The pump still runs every 3 hours. So the water is not leaving the pump/bladder in to the house.

We drained the bladder's water. The tank does not seem to have any water left in it.

Do you all have any ideas?
