Hello. I have a problem. I friend gave me an older Cal VIP Series Spa portable hot tub which I'm going to set into a outside deck. The spa has very little outside plumbing. Only where pump and heater are. I can't figuar out how to hook up the water and air to pool. It's hard to find a manual for something when you don't know what year it is. This spa has these 2 pipes ( a T joint ) coming out right side of pool with a "flange on top" and a single pipe to the left. Has a "Red smaller hose" and a "blue smaller line". A spa repair guy said he had NO IDEA about that fitting. Something for sure screws down on top.
Can anyone please direct me in a way to go. I'm new. will try to put pics in profilepool 2.jpg
