Welcome to our forum.
I have a Sundance Altamar 850 that is currently sitting at a vacation home, without power (property runs on generator, which is off). I'm concerned about freeze damage to the components outside the tub before I get back to reheat the spa. The exact situation is: Mon, 10/8 - Tub at 102. Turned power off, put spa cover on.This week we'll have highs in the 50s with lows around freezing.Two nights, however, the forecast has turned unexpectedly colder - lows between 20 and 25 degrees, with daytime highs in the 30s. I'll be back at the end of the week to turn power back on and heat the spa, but I'm not sure if I need to go back sooner with the colder forecast.In this situation, is the water outside the body of the tub, such as in the plumbing lines, pumps, etc. in danger of freezing? My experience so far has been that the water is still in the 70s when I get back after a week away, but I'm now second guessing the vulnerability of the other components.Any advice appreciated.
What are the options if you are without power for days to keep spa and components above freezing?
