I am going to try and winterize my PUP this year. I understand all the procedures as far as draining, blowing out the lines and by passing the water heater. My water pump is in a tight spot and trying to get a connection from the antifreeze to the pump is tough (plus I am notorious for breaking things). My question is if I use a hand pump and hook it to my municipal water connection and fill the water lines will the antifreeze get to my water pump and keep it safe from freezing? I get the sense from YouTube videos that it will work, but I haven't seen anything that answers the question specifically.
