Motor repay is in a tire thread but what are the steps to drain everything and protect against freezing temps when pool can't run. I know to pull the drain plug on the filter and pump. I assume the booster pump is ok as is. I have a heater that is not working at the moment, but I know there are drain plugs on it to. Anything else? What do I do about the water in the lines underground. It's going to get down to 23 Thursday night. Not a real deep freeze but just worried.
