Just getting ready to use our new Ameri-lite TT for the first time, were flushing the antifreeze from our system and found water is continually streaming from the pressure value of our Sububan water heater. The heater has never been turned on yet, as the unit was winterized since we purchased it during the winter. Happens with both city water hook up and fresh water holding tank. Any one know what this might be? We are thinking defective pressuer relief valve? Planning on calling the dealer on Monday, but was hoping to have some idea from some experienced RV'ers.
