I don't read much about pools and spas, but I have heard several times that you only run saltwater through proper saltwater equipment. How about a Softub? Are all of the internals plastic?
Hear's the background: I might be getting rid of my working Softub. I have a crazy idea of using the motor pack to partially heat my above ground pool. I will take care of the layout, routing, and connections. The pool is seasonal and only up 3-4 months per year.
So, what will possibly occur if I were to run saltwater through the Softub motor pack? What's inside these motor packs?
