Do the 2011 230 rs have low entry valves. I do not remember seeing any when we winterized. Also I see all this talk about putting a bypass by the pump to directly suck up antifreeze. I followed directions where we bypassed the hw tank, took the drain plug out added antifreeze to fresh water tank , then had all faucets, shower head, toilet go til pink stuff came out.put in city water inlet and then pressed check valve til , pink stuff came out and shot me in the eye!!!then added the antifreeze to all drains and toilet. We have had a mild winter. Does this not work??.
