I need a plumbing disgram for a Hot Spring - Produgy portable spa. I do not know the age. The Serial number is H-141098. The circulating pump is diconnected and I am not sure how it should be connected. Jet pump appears to work okay.

Where can I get a detail of the plumbing run for this spa?

We won't hve diagrams for this but contacting Hot Springs may pay off. Hot Tubs by Hot Spring ? Portable Spas, Spa Parts and Hot Tub Accessories
