I apologize for demeaning some of the replies, however there is usually a
right way and usually a wrong way to do most things. Because someone does
something wrong for many years,with no adverse consequences,doesn't make it
right. It may just make them lucky. Some folks would prefer not to play
Russian roulette, and just do the thing right from the beginning

Our pool has a design flaw (or maybe not, I've never paid much attention
to how other pools are done)..

Where the main drain line exits the ground and goes into the pump area,
there is a 4' or 6' length of PVC pipe that is exposed, and can't be
drained without draining the entire pool. The question is: How to freeze
protect this piece of pipe? Thermostat regulated heat tape and some wrap
on insulation? Build a box around it with a lightbulb inside? Maybe one
of those 1,000 watt ceramic heaters with a thermostat?

I'm in Atlanta, and our winters usually have a few days (or nights) of
sub-20 weather, with a rare plunge below 10, and the very rare plunge
below 0.

Suggestions appreciated.
