I noticed the same problem at the faucet when "city" water is hooked up and
the switch is moved from "city" to "off" to "tank."  I could see bubbles and
water moving backwards in the tank line from the faucet.  Also, when moving
from "off" to "tank" and back I could see backflow with bubbles from the
faucet towards the tank.  Maybe there are some seals in the faucet that are
worn or just old.--
