Hot Tub 1-Inch ON/Off Neck and Waterfall Valve Insert with O-Rings Compatible with Marquis Spas DIY350-6326

Fit my 2020 Catalina Nantucket spa waterfall feature perfectly.

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!

It works fine but does not turn as easily as the original, and I did lube it with the lube provided.

Good replacement part. Works good

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.

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.

It works but it does not come with rubber washers and labor be as shown- rubber washers need replaced also- I ordered 3 only one came with all components shown

this item fit my spa perfectly. Hard to find the part number online but. Success.
