Great forum - I hope someone can help with my question. We are leaving for vacation in the next week and it also happens to be the time to drain our hot tub. Is there a concern if we drain it, leave it for a week, and then refill? I would like to avoid any stuff growing in it while we are gone. I was just going to drain it without vacuuming water from the jets and was not going to drain the pumps. Any advice and guidance on how to prepare it would be appreciated.
