### ⭐⭐⭐⭐⭐ Must Have for your Well
*by J***D on December 13, 2025*

A must have Check Valve for your well pump to prevent water going back into the well. Works great and its made well. I highly recommend this check valve.

### ⭐⭐⭐⭐⭐ Good unit at the price
*by J***Y on April 21, 2025*

Not as substantial as an American made unit but serves well on my irrigation pump.

### ⭐⭐⭐⭐⭐ Solid Unit With Robust Body And Accurate Thread Fittings
*by S***’ on October 29, 2025*

This is a well made heavy duty robust all brass check valve that has a definitive one way arrow etched into the side of it designating the correct installation for proper water flow. The fact that the thread size is presented in the promotional literature really helped me plan for the right adapters before installation . Seems to work very well on my new pressure tank setup and I have had no issues with it at all.
