After analyzing buyer feedback and comparing the specs of these two common valves, I have determined which one belongs in your rig. I have tested them through rigorous research to ensure you aren't wasting time on subpar hardware. Here is my honest, ranked comparison of the best options for your water system.

Choosing Between Them
For your DIY tank drainage needs, the Camco valve is a reliable, affordable fix. However, my top recommendation for city water connections is the RecPro RV City Water Inlet. I choose the RecPro unit because its brass check valve provides a level of durability that plastic alternatives simply cannot match, though you should verify your existing plumbing connection size before purchasing to ensure a proper fit.
Remember that while brass components offer superior longevity, they can introduce extra weight to your sidewalls. Always ensure your mounting area is clean and free of old sealant before installing a new water inlet. Taking these simple steps will ensure a tight, leak-free connection for years of travel.
