In storage, mine is off.
Leave storage, all power, water pump and flush are on.
I have two lavs with the switch in only one bath. I would not want to be in the wrong lav if I needed to flush.
My vacu-flush has at times, kicked on the vac pump uncommanded, usually during the night. Only then have I turned it off.
