Do you have a tank-style water heater? Here's a link to the P4 Nautilus Water Panel we generally use. I believe to bypass the water heater, the Red handle is turned sideways. See this on page 4.
Yes I do and I followed the instructions. I did move valves around trying to get the pump to suck. But not long enough for the water heater to be full of anti freeze. Will have to see what happens next time. Thank you for the link and the info.
