Weird water problem need help

The second problem you are having is that there is a check valve on the water pump and if that gets hung up it will allow water to enter the fresh water tank while you are connected to city water.  The easiest way to get the check valve working again is to 1) shut off the water from the city water, 2) pull water via your water pump out of the fresh water tank (pump 1 to 4 gallons per session).  Then go back on city water.  Repeat several times. The check valve should start working.  As to the water going to the toilet, there may be an obstruction in the feed line to your toilet. You can disconnect the water feed line at the toilet and allow the water line to flush itself out for a short period.  The water running out of the water line should just go down the shower drain to the gray water tank.  Hope this helps.    

So far so good. It went all night here at the campground without flowing into the fresh water tank. I bet that was it. Thanks again!
