Review on Joywayus Female Backflow Preventer Thread by Cody Stroop

Revainrating 1 out of 5

leaks. Huge waste of time.

The 3/4" NPT thread is not a standard size. The thread is too loose. The 3/4" male adapter just falls all the way down. Also with 5-10 layers of Teflon tape. I've spent several hours of my time installing and reinstalling these things to try and get them to stop leaking. Vain. I've been a plumber for over 30 years so it's not a question of technique or skill. Valves are just crap. Looks like I'll pay for something big like Watts so I don't have to spend more time changing valves.

Pros
  • This valve is used to prevent liquid backflow.
Cons
  • High price.
