Vacuum Breaker Only for Belvedere Shampoo Bowl Salon Use

It was not a Belvedere vacuum breaker. It was a knock off by Jeffco. I payed more thinking I was getting the Belvedere. It works and I needed it so we had to use it. You can see the difference in quality by comparison...

This is not even a Jeffco breaker. After a year, it has begun to leak. I called Jeffco to request a repair kit but they told me this is not a Belvedere knock-off but a Jeffco knock-off. Saved money and it worked for a year. I do like that it has metal threads. I do not find that it feels flimsy compared to my Belvedere breakers. I'm going to try a Belvedere 403 repair kit (my Belvedere breaker also has a leak). Hopefully, it will work with the "Jeffco" too.
