Adding a shut off valve to your RV's plumbing fixtures is a simple yet crucial modification that can save you from a lot of headaches down the road. We found a great video that walks you through the process, and you can watch it at the bottom of this article. In the meantime, here are the key steps to installing a supply line shut off valve in your RV.
1. Importance of a Shut Off Valve
Installing a shut off valve on your RV's plumbing fixtures, especially the toilet, is essential. It allows you to isolate and address issues without disrupting the entire water system. This is particularly useful when you need to clean or replace the toilet seal or if the foot pedal flush valve fails, which is a common occurrence.
2. Necessary Components
To install a shut off valve, you will need an angle stop and a braided line. The angle stop connects to the PEX pipe, and the braided line then connects to the toilet. Jared recommends replacing any existing tubing with PEX for better durability and reliability, as PEX is less prone to leaks.
3. Cutting and Crimping PEX
PEX is easy to work with and can be cut using a utility knife or a specialized PEX cutting tool. When attaching the PEX to the fitting, ensure the pipe is fully seated and the crimp ring is positioned correctly. Use a crimping tool to secure the ring, ensuring a long-lasting and leak-free connection.
4. Replacing Existing Tubing
If your RV has tubing instead of PEX, it's advisable to replace it with PEX. Tubing is more prone to leaks, and PEX offers greater strength and reliability. Jared demonstrates how to cut out the old tubing and replace it with PEX, using a brass tee for better durability.
5. Installing the Angle Stop and Supply Line
Once the PEX is in place, crimp on the angle stop and connect the braided supply line. These braided lines are easy to install, using a compression fitting that seals itself when tightened properly. This ensures a secure and leak-free connection to your toilet or other fixtures.
6. Additional Tips
Before cutting into any pipes, make sure to turn off the water and relieve the pressure. Use a collapsible bucket and a rag to catch any residual water. This helps prevent water from getting into electrical components or other sensitive areas.
Installing a supply line shut off valve is a straightforward modification that can greatly enhance the functionality and convenience of your RV's plumbing system. For a detailed walkthrough, be sure to watch the video at the bottom of this article. Happy RVing!
