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)
This valve ranks as a top choice because of its straightforward utility for basic tank drainage tasks. It is a simple piece of equipment that gets the job done without extra complexity.
I appreciate that this unit includes a flange, which makes mounting it to your tank significantly easier. It fits both 3/4-inch or 1/2-inch tubing, offering the flexibility you need for various plumbing setups. However, because it is made of plastic, I would be careful not to overtighten the connections during installation.
Buyers appreciate the simple design for basic maintenance.
The inclusion of a flange simplifies the installation process.
Plastic construction requires a gentle hand to prevent cracking.

2. RecPro RV City Water Inlet | Black | Brass Check Valve
This valve is ideal for the owner who wants a permanent solution and prefers not to replace their hardware every season. If you want to avoid the common issues of stripped threads or cracked housings, this is the hardware you should reach for.
The inclusion of a brass check valve is the primary reason this is my top overall pick. Brass behaves like a solid anchor in your plumbing system, providing a level of durability that basic plastic valves simply cannot match. While it costs a bit more, I believe the long-term peace of mind is well worth the investment.
Users report high satisfaction with the durability of the brass components.
The inlet is designed to replace standard city water connections.
The black finish provides a clean look on the exterior of most rigs.

3. Himaweek RV City Water Inlet with Check Valve Water Fill Inlet Connection
This unit features a distinct integrated design that combines the exterior flange and the check valve into one assembly, making it an efficient choice for a quick exterior refresh. It is meant for someone looking to swap out an old, yellowed inlet with minimal hassle.
I like that it arrives ready to mount, which reduces the amount of time you spend working outside the rig. It functions as a direct replacement for most standard city water connections. You should keep in mind that the plastic housing might not be as impact-resistant as metal, so you should ensure it is properly seated against the sidewall to avoid gaps.
Buyers find the installation process to be very efficient.
It acts as an effective replacement for older, worn-out inlets.
The integrated design keeps the exterior appearance looking sharp.

Choosing Between Them
I recommend the RecPro RV City Water Inlet for those prioritizing long-term durability, while the Camco RV Water Tank Drain Valve serves best for those tackling simple tank drainage projects. If you are focused on an easy exterior cosmetic upgrade, the Himaweek RV City Water Inlet is a solid contender. In my judgment, the RecPro option is the most reliable choice for a permanent plumbing fix.
The RecPro RV City Water Inlet is my top choice because its brass check valve provides the structural integrity necessary to prevent leaks. You should always remember that plastic-to-metal fittings require careful installation to avoid cross-threading, regardless of which product you purchase. Taking your time during the setup phase will ensure your system remains dry for years.
