1. Camco RV Water Tank Drain Valve | Features a Durable Plastic Construction, Comes with a Flange, and is Used with 3/4-Inch or 1/2-Inch Vinyl Tubing (22223)

The built-in check valve prevents annoying backflow effectively.

Choosing Between Them
In my view, choosing the right plumbing hardware comes down to matching the part to its specific job on your rig. I'd point budget-conscious owners toward the Camco RV Water Tank Drain Valve for basic holding tank maintenance, but my ultimate top pick is the RecPro RV City Water Inlet for its superior metal construction.
Do remember that these components serve entirely different parts of your plumbing system, so you may eventually need both in your toolkit. Taking the time to replace worn fittings now prevents costly water damage down the road.
