I have a Prodigy by Hotsprings. It's about 8 years old, and has been a pain in the back side ever since I bought the house 4 years ago. One repair after another. Yet, I have one more.

The tub was working until I drained it and cleaned it. Now the recir pump turns on and stops. It was replaced last year (big $$) and I took it apart, and it is clean. But, I did notice that the small tubing that runs every where is full of calcium.

My question is, since I can only see one end of the tubing, how can I replace the tubing?

Thanks
