If what you say is correct, the pump has to be located lower than the
bottom of the pool. In any event, if you can't drain it or blow the water
out of the line, or use pool antifreeze, use a low wattage heat tape on
the pipe and insulate around it. That would be the least costly solution

Right you are... The pump is 5' lower than the full level on the pool, and 3
1/2 feet lower than the pool's winter level (below the skimmer)...

Like you, my gut tells me that the heat tape is the best option.

Thanks,
