## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    It works
  

*by G***  on Reviewed in the United States 🇺🇸 on May 22, 2022*

I installed this on my rv because the built in check valve on two of my water pumps failed. Because of location, it was installed on the lift side of the pump which works but being brass casing with a brass ball it chatters at low volume. It might not do that on the high pressure side. Never the less, it’s been doing it’s job for the last 3 months which was frustrating before when I’d find water flowing out of my fresh water tank vent when hooked up to an outside connection

### ⭐⭐⭐⭐ 







  
  
    About time
  

*by B***L on Reviewed in the United States 🇺🇸 on July 11, 2021*

I have bought 3 valve so far , it about time I found one that works with high flow but low pressure. So anyway it’s working right so far. Only thing I didn’t like was it slow my flow down some. Will see if it last. I’m using it on my hydroponic system and working so far. I try to update and let you know how it does work in the long haul

### ⭐⭐⭐ 







  
  
    Broke after a few Months of use
  

*by E***N on Reviewed in the United States 🇺🇸 on December 8, 2022*

It was great at first but the little bar inside that stops the ball from blocking the flow in the right direction broke after a few months of use. Hard to spend that much money on an item that doesn’t last but a few months.
