I got my Dreammaker tub about 2 weeks ago and my neighbour keeps complaining about the noise from the pump (not the jets). Where I live (Toronto) it gets well below freezing at night in the winter. If I unplug the tub every night for 8 hours to keep him happy, will the lines be likely to freeze? I believe they're all inside the insulation, but I don't know for sure. I can keep track of the temperature in the tub itself, but I don't know about the lines. Does anyone have any experience with this sort of thing with this or any kind of tub?
