Thanks for the reply. I'm going to cap it to prevent water from pouring out.

I have a 2003 Del Sol Hermosa and upon opening the cabinet, there is a 1/4 in ID flex hose with a clamp on the end that is dangling on the right side of the cabinet opening. Yesterday, the tub was draining from this hose. The hose seems to go to the top of the tub throught the insulation and if I blow into it, the right side well jet blows air. When I activate the pump, air gets sucked into this tube. The I noticed this tube a while ago but this was the first time water drained from it. Does anyone have a schematic of the hoses for this spa? I can't find any connection for this hose.
