I winterized The Beast yesterday afternoon and had a problem this go around that I didn't in the past. I turned the water heater bypass valve to flow thru and bypass, turned the fresh water tank valve off, opened the winterization valve and left my water heater anode out to see what happens. Voila! My water heater began to spew pink stuff as I pumped it thru. Shutting the bypass valve made it worse, so I opened the bypass again, put the anode back in and ended up winterizing the washer/dryer and all faucets, toilets etc but used a considerable amount of pink stuff.
WTF happened and where did I go wrong? Shouldn't opening the water heater bypass keep anything from filling it when suctioning out with the winterization hose\valve? I must have forgotten to do something.
