Preventing Water Damage Following RV Plumbing Repairs

This post was updated on March 15th, 2024

Owning an RV means embracing both adventure and the occasional repair, especially when it comes to RV plumbing. The trick to avoiding extensive water damage isn’t just in fixing leaks or bursts promptly but in taking proactive steps to ensure no further damage ensues.

Step 1: Recognize the Early Signs of Potential Water Damage

Being proactive can significantly mitigate the risk of water damage. Pay attention to these early warning signs:

  • Water Pump Behavior: An RV water pump that frequently cycles on and off may indicate a slow leak in the system, causing the pump to activate to maintain pressure.
  • Unexpected Water Accumulation: Water pooling underneath the RV, especially if you’re on a dry surface, could be a sign of a leak. Differentiate this from AC condensation, which typically exits from specific drainage points.
  • Moisture in Storage Areas: Dampness or wetness in storage compartments is a clear signal that water is getting where it shouldn’t. Investigate any soggy carpeting or walls for potential leaks.

Step 2: Execute a Thorough Pressure Test Post-Repair

  • Testing is Key: Always perform a pressure test on the water system. This involves running the water pump and closely monitoring for leaks, especially around newly repaired or replaced fittings. This step is critical before sealing up any panels or walls you had to access during the RV plumbing repair.
  • Material Matters: Be aware that RV interiors often utilize materials like particle board, which can swell and deteriorate when exposed to water. Catching leaks early can prevent damage to your RV’s structure and interior.

Step 3: Inspect and Reinspect Your RV Plumbing Work

Once RV plumbing repairs are completed:

  • Comprehensive Checks: Inspect the repaired area and any plumbing fittings you interacted with during the repair process. It’s not uncommon for nearby fittings to become loose inadvertently.
  • Securing Connections: Ensure all connections are tight and secure. Even if you haven’t directly worked on some components, the act of moving around in tight spaces can lead to accidental shifts or loosening.

Step 4: Methodically Dry Out Wet Areas

After addressing the leak:

  • Air Circulation: Open all affected areas to air. Use fans to promote faster drying, especially in confined spaces.
  • Deal with Dampness: For wet carpets or upholstery, remove or pull them back to expose the underlying floor or structure. Direct fans to these areas to expedite drying. Remember, moisture trapped under flooring can lead to mold and structural damage over time.
  • Moisture absorbers: In areas where air circulation is limited, consider using moisture absorbers or dehumidifiers to draw out the dampness.

Step 5: Swift Action at the First Sign of Leakage

The moment you suspect a leak:

  • Immediate Response: Turn off the water supply to prevent further leakage. Locate the main water shut-off valve for your RV and use it the moment you suspect an issue.
  • Source Identification: Carefully locate the source of the leak. Sometimes, the issue might be apparent, but other times, it may require a bit of detective work. Don’t hesitate to seek professional help if the leak’s source isn’t obvious.

Step 6: Preventive Measures & RV Plumbing Maintenance

  • Regular Checks: Make it a habit to inspect your RV’s plumbing system regularly. Examining pipes, hoses, and connections can help identify potential issues before they escalate into leaks.
  • Familiarize Yourself with Your RV’s Plumbing: Knowing the layout of your RV’s plumbing system is invaluable. Understanding where pipes are located and potential trouble spots can make prevention and quick leak detection much easier.
  • Incorporate Water Alarms: Consider installing water alarms in areas prone to leaks, such as under sinks, near the water heater, and in storage bays. These devices can alert you to the presence of water early on, enabling you to address leaks before they cause significant damage. Water alarms are a cost-effective addition to your preventive maintenance toolkit, offering peace of mind and an extra layer of protection against water damage.

Final Thoughts

Preventing water damage after plumbing repairs in your RV is about diligence, proper testing, and effective drying techniques. By following these detailed steps, you can protect your investment, ensuring your RV remains a safe and comfortable home away from home on your travels.
