Review: Fixed my water heater - My hot water in my rv was super low on pressure. I was starting to think the heater was cloged with sediment or something but turned out to be this check valve! They have a plunger and spring in one end to keep cold water from back flowing into hot water tank. What happens over time is the clip fails and the plunger gets stuck in the out going side of the tank restricting flow. I just switched my old one out with this quality part and hot water flows just like new. Would highly recommend this valve.
Review: Works well! - Fit and function are good. Requires a bit of pressure or suction to open.

### ⭐⭐⭐⭐⭐ Nice brass valve
*by D***D on December 20, 2025*

The check valve seems to be well made and should hold up overtime. It's made of brass and has plastic valve parts. It fits nicely and I strongly recommend it. I recommend the seller as well.
