...hard to get that just off the posts. But yeah...now i understand. Is your pump in line with the heater. Cause if it is...might be a cracked heater core thats leaking and causing both problems. Did the previous owner say if it sat empty over winter. Cause thats a huge mistake, since you cant ever fully drain a hot tub...some water will always remain. Plus rain and snow can easily work there way into the tub and fill the plumbing. Hopefully its an easy fix though.
