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!

Perfect fit for my Catalina hot tub
I found this doing a search for a replacement fountain control valve. It was easy to use and it even came with a small tube of silicon grease to lubricate the cartridge. VEry good price vs the OEM units

Doesn't work.
I put this replace part in as instructed. It fit but it doesn't turn the waterfall off and it won't come out so I cannot replace it.
