Is it okay to drain my hot tub when I am not using it for long periods?

Um... is this allegory?

Rubber parts will eventually dry out,like o-rings and seals.A lot of people store theirs by draining it for the winter.
Make sure the tub is empty in the piping/jet channels and leave the filter out to dry also
Leave a little 'breathing room' for the cover ,as water finds a way in the tub .
