'06 Phenix<br/><br/>Very strange...pulled the coach out of storage with intent of draining fresh water tank to the grey. Fresh had about 50%. Turned on water pump and kitchen faucet. Ran ok for a few minutes then water stopped flowing; replaced by sound of air in the line, spitting out water. <br/><br/>Filled the tank to 80% and started again. Same thing happened at about 50% level....
