Getting colder and want to keep using our inground spa while I stop heating the pool in preparation for closing it for the winter. I"m guessing I should keep the spa cover on to keep some heat in, and I'll still run the spa and pool filter to keep water balanced. There is a 2" pipe about 5' long that connects the spa to the pool, can anyone tell me the purpose of this in the pool design? Could I put a plug in this for the next month or two to keep the warmer water in the spa?
Thanks,
Dave
