The difference between a functional plumbing system and a messy leak is almost always the material quality of your valves. After analyzing buyer feedback and technical specs, I have ranked these two solutions to help you solve your specific plumbing challenges. I prefer the Camco unit for general maintenance tasks. Here is the honest breakdown of how these two components compare for your next RV repair project.
| Best For | Product | Name | Score | |
|---|---|---|---|---|
| Simple Tank Drainage |  |
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) | 9.8/10 | Check Price |
| City Water Connections |  |

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 earns the top spot because of its straightforward design and ability to fit the most common tubing sizes found in recreational vehicles. It serves as a reliable replacement for standard fresh water tank drains that have become brittle or stuck.
I find that the inclusion of the mounting flange makes a significant difference during installation, as it provides a secure surface to prevent leaks. While the plastic construction is efficient for its intended purpose, do keep in mind that it will eventually require replacement after several seasons of intense sun exposure.
Buyers appreciate how the simple architecture minimizes the risk of internal mechanical failure.
The valve is widely praised for its compatibility with both 3/4-inch and 1/2-inch tubing.
Many users note that the compact size fits into tight spaces where larger metal valves would not go.

2. RecPro RV City Water Inlet | Black | Brass Check Valve
This inlet is best for the owner who needs a robust replacement for a pressurized city water connection on their exterior sidewall. It functions as a critical barrier to keep water flowing into your rig while preventing backflow from your internal plumbing.
The inclusion of a brass check valve is the primary reason I would choose this over a cheaper all-plastic alternative. Brass is simply better at resisting the constant pressure of a campground water source, though you should handle the installation with care to avoid stripping the plastic housing threads.
Users commonly report that the brass internal components provide a much longer service life than standard plastic valves.
The black finish is frequently cited as a preferred aesthetic match for modern RV exteriors.
Some buyers note that the installation process is quick if you have a sealant on hand for the exterior mounting plate.

Choosing Between Them
I recommend the Camco Water Tank Drain Valve for anyone needing a flexible solution for tank management, while the RecPro City Water Inlet is the superior choice for those upgrading their exterior pressurized connections. My pick for the most essential item is the Camco valve because it offers reliable versatility for common maintenance tasks. You should keep in mind that most plastic components are subject to long-term degradation when constantly exposed to UV rays, so plan your maintenance accordingly.
Regardless of the part you choose, remember that proper sealing is just as important as the valve itself. Ensure you use the correct plumbing sealant or gaskets to prevent water from seeping behind your RV siding. A little extra time spent during the initial install prevents a massive headache later on.
