Troubleshooting wastewater tanks in an RV can involve several steps to identify and resolve common issues. Here’s a guide for diagnosing and fixing problems with gray and black water tanks:

Initial Checks

  1. Visual Inspection
    • Inspect the tanks and pipes for signs of leaks or damage.
    • Check the connections to ensure they are tight and watertight.
  2. Tank Fill Level
    • Check the tank fill levels using the level gauges or by emptying them to estimate their content.

Common Problems and Solutions

Gray Water Tanks

  1. Unpleasant Odor
    • Cleaning: Empty and clean the tank using a mixture of water and baking soda, or use a specific gray water tank cleaner.
    • Traps: Make sure the traps under the sinks contain water to prevent odors from rising.
