I assume you are describing a spa which is permanent and attached to an inground pool via shared Plumbing. If so, then the builder installed an inline check valve to prevent the water from running back down through the plumbing from the spa to the pool when the equipment is turned off. There are primarily 2 types of check valves. One has a weighted flapper which opens with the water flow and drops closed when the flow stops, and the other is a spring-loaded diaphram. (ref: In your case, the check-valve is now either stuck open (usually from wedged-in debris ie: leaves, sticks, etc), or the "innards" are broken. In either case you need to gain access to at least one end of the valve and look inside to see what has happened.
