This is a 3 year old Caldera Spa Vancanza model. Noticed dropping water level. Once panel was opened, an open ended vinyl tube was dripping. Seems to happen when heating up. The tube runs on left side and disappears into sealed area I can’t get into with lifting entire hot tub. I’m going to plug it but any thoughts on the cause? Thanks in advance. Video below.
