Your RV is your home on wheels, providing comfort and convenience wherever you go. However, when plumbing issues arise, they can quickly put a damper on your adventures. In this article, we’ll explore some common RV plumbing problems and provide solutions to help you troubleshoot and resolve them. By following these tips, you can ensure that your RV’s plumbing system keeps flowing smoothly, allowing you to focus on enjoying your camping experience to the fullest.

  1. Preventing Toilet Clogs: One of the most common plumbing issues in RVs is toilet clogs. Often, these clogs occur due to excessive toilet paper usage or insufficient water flow during flushing. Educate everyone in your RV about the right way to use the toilet, emphasizing the importance of using an appropriate amount of toilet paper and ensuring an adequate water supply for effective flushing. You might also consider installing a bidet, which can dramatically reduce the amount of toilet paper used in your rig in general.
  2. Proper Black Water Tank Management: Leaving the black water drain pipe open continuously when connected to a sewer hookup can lead to troublesome clogs. By allowing the liquid waste to drain first, solid waste can accumulate, resulting in a sludgy clog within the holding tank or sewer drain pipe. To prevent this, always keep the black water valve closed until the tank is nearly full before emptying it. This practice ensures better waste flow and minimizes the risk of clogs.
  3. Clearing Clogs: If you’ve got a clog, it can be a bit of a nightmare. There are a number of options available to you in trying to break things free you can try. Attaching a flushing connector to the tank and using positive water pressure to “push” the clog back into the tank is one option, just make sure you don’t overfill the tank and flood the interior! You can also try taking the RV for a drive, often the bumpy nature of the road can help break loose the clog and help a stubborn clog drain. Sometimes, on that note, even a few light taps on the tank or piping with a rubber mallet can accomplish the same goal. In the unfortunate event of a clog where nothing else has worked, snaking the line is often the best solution. Access the RV’s exterior and use a plumbing snake through the black tank drainage valve to clear the clog effectively. In any case, be cautious and consult a professional if you are unsure or lack the necessary equipment. Avoid using commercially-available products like Draino, as they can interact negatively with RV toilet chemicals and may not be effective in resolving the issue.
  4. Leaky Pipes: Leaky pipes can be a frustrating issue in any RV plumbing system. However, if your RV utilizes PEX (cross-linked polyethylene) piping, addressing and resolving leaks can be relatively straightforward. PEX pipes are a popular choice for RV plumbing due to their flexibility, durability, and resistance to freezing temperatures. Here’s how you can tackle leaky pipes with PEX solutions:
    • Identify the Leak: The first step is to locate the source of the leak. Inspect the PEX pipes carefully, checking for any visible cracks, loose connections, or damaged fittings. Remember to turn off the water supply before proceeding with any repairs.
    • Replace Damaged Fittings: If you notice a faulty or damaged fitting causing the leak, you can replace it with a new PEX fitting. Cut out the damaged section of the pipe using a PEX cutter or a sharp utility knife. Ensure that the cut is clean and square. Insert the new fitting into the cut ends of the PEX pipe, ensuring a secure connection. Depending on the type of fitting, you may need to use a crimping tool or a cinch clamp to secure the fitting in place.
    • Use PEX Repair Couplings: In some cases, the leak might occur along the length of the PEX pipe rather than at a specific fitting. PEX repair couplings can come to your rescue. These couplings are designed to fix leaks by connecting two ends of a cut PEX pipe securely. Follow the manufacturer’s instructions to cut out the damaged section of the pipe, and then insert the repair coupling to join the two ends together. Utilize crimp rings or cinch clamps to ensure a watertight connection.
    • Properly Secure PEX Pipes: To prevent future leaks, it’s essential to secure the PEX pipes properly. Use pipe clips or straps designed for PEX pipes to fasten them securely to the RV’s framework or existing supports. This prevents excessive movement and reduces the risk of wear and tear that could lead to leaks.
    • Consult a Professional if Needed: While PEX pipe repairs can often be done by RV owners themselves, there might be instances where professional assistance is required. If you’re unsure about your ability to repair the leak or if the issue seems more complex, don’t hesitate to reach out to a qualified RV service technician for guidance and assistance

      By addressing leaky PEX pipes promptly and effectively, you can maintain a reliable and efficient plumbing system in your RV. Regular inspections and proactive maintenance will help you catch any potential leaks early on and prevent them from escalating into more significant problems. With the flexibility and durability of PEX pipes, you can enjoy worry-free travels and have confidence in your RV’s plumbing system.
  5. Winterizing Your RV: If you plan to travel to cold regions during winter, or are storing your RV in cold climates, it is crucial to be mindful of any water lines that might run the risk of freezing in your travels. When storing, winterize your RV’s plumbing system to prevent frozen pipes. Use RV-specific antifreeze and the water pump to circulate it throughout the system, protecting your pipes from freezing. In most RVs there is a specific place the manufacture has installed to allow easy access to injecting antifreeze into the system. Refer to our comprehensive guide on winterizing your rig to ensure proper steps and prevent common winter RV plumbing problems.

Maintaining a fully functional plumbing system in your RV is essential for a comfortable and enjoyable camping experience. By familiarizing yourself with these common RV plumbing problems and their solutions, you can tackle minor issues on your own and prevent future complications.
