*by U***N on October 30, 2023*

Simple installation, worked great, hottub is back in business. Glad this was the only issue, probably about the cheapest fix.

### ⭐ A very short life
*by M***M on December 21, 2025*

A short life to failure. Less than 4 months after hot tub ozinator installation, check valve no longer functioned as designed. Seller contacted but would not provide replacement or credit. Not a good value.
