I am in Ohio. In ground pool. Do most people just drain below the skimmer but keep the water above the other returns? I was at the pool store and they said they just blow out the lines that are below the water level and cap them. They said they don't add antifreeze to these lines (one return and one that pushes water in the pool), but do add it to the skimmer above ground. Does this sound right?
Also, I have found that I probably have some sort of small air leak in my pipes and alway loose my prime if the pump is off for a short while. I am wondering if this will cause problems in the winter.
