Hi, I heard that too about the heater. I do plan on getting a "Buy N Sell" and looking to see if I can get a good used one. Fo you know why I cant vacumn to waste? I think I am doing something wrong.................. I put water through my hose and hook it up, very good suction and then I go and turn to waste...........hose comes out, suction doesnt work............do I have to turn to waste and then put my hose in?? Do I put water in??
