## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great on hot tub ozonator
*by G***T on November 26, 2024*

Previous models got waterlogged once a year - this one restored the ozone bubbles and seems more rugged - better material. After six months, all good.

### ⭐⭐⭐⭐⭐ It Works As Intended
*by R***N on June 22, 2023*

Replaced faulty (old) check valve. Make sure you verify flow direction, it is very tight fitting (this is a good thing as the system is under pressure).

### ⭐⭐⭐⭐⭐ As advertised
*by R***B on July 14, 2023*

My hot tub is back up and running.
