Fixed our tub
Our hot tub was leaking, because the waterfall feature knob couldn’t be shut off and was running continuously. We did a little googling, and discovered that a small part inside the knob had worn away or disintegrated, so the integrity of the knob just wasn’t good anymore. A few bucks on this replacement part, and we quickly fixed our problem! The waterfall turns off no problem, and actually switching out this part was a cinch. Definitely a great value!

Fixed Aquaterra waterfall
This is the part that broke probably causing my pump and control board to fail. The rubber seal from this was missing and most likely stuck in the impeller causing overheating.If your waterfall won’t turn off I suggest replacing this part sooner than later.
