I used this to keep the city water from filling my freshwater tank in my RV. I put it on the suction side of the pump and it worked great!

I was having issues with the water pump on my camp trailer cycling on about every 15-20 minutes. I thought possibly I had a leak, but could never find it. I installed this backflow preventer on the inlet to the pump and the problem went away. The issue turns out to be the pump itself bleeding down. I haven't had an issue since installing the check valve. The quality of material is very good.

Good, spring loaded check valve. Be aware it is spring loaded and requires a bit of pressure to open the valve. This is perfect for preventing inadvertent crossover mixing of cold -> hot in comfort hot water recirculation system.

Bought this years ago to replace a potential valve failure on my RVs water heater. It never failed. Just replaced the OE water heater this year, and used this to replace the oem plastic valve. seems to work fine.

Unlike gasher and other Chinese brands, this one actually works. NPT threaded and to spec. 5/5

I bought these (one as a backup) for the hose that's used to supply water to my RV's black tank rinsing system.Big mistake on my part: They're too small for hose connections.If you ignore the fact that they're made by Camco (sellers of everything RV, including the water hoses that I've bought over the years) and actually read the description and packaging, you'll see that they are for heaters, not hoses. Mea culpa.The fittings seem to be well made, though.

We purchased this item rather than replacing the entire water pump. Our water pump was allowing the fresh water tank to fill when we were using the city water inlet, due to a a faulty back flow preventer on the water pump. Rather than spending 6-10x as much for a new water pump, we tried this product. The entire install took less than 10 minutes, including the time it took to access the water pump.
