Bathroom Faucet Doesn't Work After Dewinterizing Your RV: Troubleshooting Guide

So, you've painstakingly dewinterized your RV, ready for that long-awaited road trip, only to find your bathroom faucet stubbornly refuses to cooperate? Don't panic! This is a common problem, and in most cases, a fixable one. This comprehensive guide will walk you through troubleshooting why your RV bathroom faucet isn't working after dewinterizing and offer solutions to get that water flowing again.

Common Causes of a Non-Functional RV Bathroom Faucet Post-Dewinterization

Several issues can prevent your RV bathroom faucet from working after the dewinterization process. Let's explore the most frequent culprits:

1. Air in the Lines: The Most Likely Culprit

The most common reason for a non-functional faucet after dewinterization is trapped air in the water lines. During the winterizing process, you likely used compressed air or antifreeze to purge the system of water. This air can become trapped, preventing water from reaching the faucet.

• Solution: Turn on all faucets and let the water run for several minutes. This will often purge the air from the lines. Pay close attention to the hot and cold water lines separately. Sometimes, air gets trapped in one line but not the other. If the problem persists after several minutes, proceed to the next steps.

2. Low Water Pressure: A Persistent Problem

Insufficient water pressure in your RV's water system can prevent the faucet from functioning correctly. This can stem from various sources:

• Low City Water Pressure: If you're hooked up to city water, check the pressure at the campsite's water supply. Low pressure here will affect your entire RV's water system.

• Clogged Water Filter: A clogged water filter restricts water flow. Replace or clean your RV's water filter.

• Debris in the Lines: Debris from the winterizing process might be lodged in the lines. This is more likely if you used compressed air that pushed sediment through the system.

• Solution: Check your city water pressure and replace or clean your water filter. If the problem continues, you might need to flush the water lines to remove any remaining debris. This often involves using a high-pressure hose attachment to thoroughly clear the lines (always check your RV manual for proper procedures).

3. Faulty Faucet Cartridge or O-Rings: Internal Issues

Sometimes, the problem lies within the faucet itself. Over time, the cartridge (the internal mechanism controlling water flow) can wear out or become damaged. Similarly, worn-out O-rings can cause leaks or prevent proper water flow.

• Solution: If you have basic plumbing skills, you can attempt to replace the cartridge or O-rings. You’ll need to identify your faucet’s make and model to find the correct replacement parts. This usually requires disassembling the faucet, so refer to the manufacturer's instructions or find a YouTube tutorial for your specific faucet model. If you’re uncomfortable with this, consult a professional plumber.

4. Frozen Pipes (Despite Dewinterizing): A Worst-Case Scenario

Even after dewinterization, some water might remain in pipes and freeze if temperatures unexpectedly dropped. This is particularly a concern for pipes exposed to the elements or poorly insulated areas.

• Solution: Check for any frozen pipes, especially in exposed areas. If you find frozen pipes, carefully thaw them using a hairdryer or heat lamp (never use open flames). This is a serious issue and might require professional help if the damage is extensive.

5. Incorrect By-Pass Valve Operation: A Specific Issue

Some RVs use bypass valves to switch between city water and tank water. If this valve isn’t properly switched to the city water position after dewinterization, the faucet won’t work.

• Solution: Ensure the bypass valve is correctly positioned for city water usage. Consult your RV's manual for specific instructions on operating the bypass valve.

Preventative Measures for Future Dewinterization

To avoid this problem next year, follow these tips:

• Thorough Flushing: After dewinterization, thoroughly flush the system with plenty of fresh water to remove all traces of antifreeze.
• Proper Winterization: Ensure you properly winterize your RV according to the manufacturer's instructions. This includes using the correct type and amount of antifreeze.
• Regular Maintenance: Regularly inspect your faucets and plumbing system for leaks or signs of wear and tear. Replacing worn parts proactively can prevent future problems.

By systematically working through these troubleshooting steps, you should be able to identify the cause of your malfunctioning RV bathroom faucet and get it working again. Remember to always consult your RV's manual and prioritize safety when working with water and plumbing systems. If you're unsure about any step, it's always best to seek professional help from an RV repair technician.
