Welcome to our forum.
I live in Delaware and right now the night temps are getting down into the 20's...we have had a few nights this year that have gotten into the single digits.I realize there are likely some pipes and pumps that didn't fully drain and there is a risk of them freezing. Maybe I'll get lucky
[Three things:1. IMO unless your tub is likely to freeze up completely, you are better to leave the tub full. The pipes will freeze slower if full of water, than air. If it is in danger of becoming a big popsicle, then fully drain and out blow pipes and winterize with anti-freeze. 2. I would suggest putting a heat source into the equipment compartment immediately... a troublelight or a small heater.3. If this is likely covered under warranty, waiting better weather and time to troubleshoot it yourself was a risk you don't want to take in freezing temps... especially if your diagnositic abilities are limited to guessing if the caps look as "rounded" as another internet poster. If you freeze anything, you will likely void the warranty.
