Camco RV Water Heater Backflow Preventer | Features a Heavy-Duty Brass with a Stainless Spring Construction and a 1/2-Inch Male x Female NPT (23303)

I purchased the Camco RV Water Heater Backflow Preventer to address my issue with city water filling my freshwater tank in my RV, and it worked like a charm! I installed it on the suction side of the pump, and it completely resolved the problem. The installation was straightforward, and the product feels solid and well-made. It’s a must-have for any RV owner looking to prevent backflow issues. Highly recommended!

Pump backfilled the fresh water tank. Thought I needed a new pump, but this was a much cheaper fix. 10/10 would recommend if you have this problem.

Feels like it’s very solid construction. Easy to install. Used Teflon tape on the installation and have some very slight leakage. I mean very slight. I’m going to get some pipe dope and reassemble and see if that stops it completely from dripping. Happy I went with brass to replace the plastic one that failed.

Be aware the thread quality on these is very tight and rough and should have been burnished by the factory. When screwing into our ABS trailer water pump, the starter threads on these are so tight that it has a tendency to cross thread. I had to file and burnish the first few threads so it would properly receive the female threads to the water pump. Other than that, it works very well to keep water from backflowing into the trailer tank when using a city water hose hookup.

Well made and an easy fix for my RV water heater problem. Turns out a stuck/clogged back flow valve is a common problem and this fixed it super easy.

Works perfectly for the bidet, much better than $1500+ for a whole new one!

Perfect replacement, no leaks, easy industrial and much better made than the plastic ones

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.
