How to Unclog a Camper Black Tank?

A clogged black tank is a common problem for RVers, but it’s one that can be easily fixed. In this guide, we’ll walk you through the steps on how to unclog a camper black tank, so you can get back to enjoying your RV trip.

Identify the Problem

The first step to unclogging a black tank is to identify the problem. There are a few different things that could be causing the clog, so it’s important to narrow it down before you start troubleshooting.

  • Solid waste: The most common cause of a clogged black tank is solid waste. This can happen if you don’t dump your tank often enough, or if you’re not careful about what you flush down the toilet.
  • Paper towels: Paper towels are another common culprit of clogged black tanks. They don’t dissolve in the same way as other waste, and they can easily build up and cause a blockage.
  • Grease: Grease can also cause a clog in your black tank. It’s important to avoid pouring grease down the drain, as it can solidify and build up over time.
  • Chemicals: Some chemicals, such as bleach and drain cleaners, can also damage the seals in your black tank and cause a clog. It’s important to avoid using these chemicals in your RV’s plumbing system.

Inspect the Black Tank

Once you’ve identified the potential cause of the clog, it’s time to inspect the black tank. This will help you determine the best way to proceed with unclogging it.

To inspect the black tank, you’ll need to access the tank through the inspection port. This is usually located on the outside of the RV, near the back. Once you’ve located the inspection port, open it and take a look inside the tank.

If you can see the clog, you can try to remove it manually using a long stick or a hose. If you can’t see the clog, you’ll need to use a different method to unclog the tank.

Unclogging the Black Tank

There are a few different ways to unclog a black tank. The best method for you will depend on the cause of the clog.

  • Chemical decloggers: If the clog is caused by solid waste, paper towels, or grease, you can try using a chemical declogger. These products are available at most RV supply stores. Follow the directions on the product label carefully.
  • Boiling water: If the clog is caused by grease, you can try pouring boiling water into the tank. The hot water will help to dissolve the grease and break up the clog.
  • Plunger: If the clog is located near the drain, you can try using a plunger to dislodge it.
  • Clog remover tool: A clog remover tool is a long, flexible rod with a hook on the end. You can use this tool to reach into the tank and remove the clog.

Preventing Clogs

The best way to avoid clogged black tanks is to prevent them from happening in the first place. Here are a few tips:

  • Dump your tank regularly. The more often you dump your tank, the less likely it is to clog.
  • Be careful about what you flush down the toilet. Don’t flush paper towels, grease, or other solids down the toilet.
  • Use a chemical declogger every few months. This will help to keep the tank clean and prevent clogs from forming.
  • Inspect the tank regularly. Check the tank for clogs every few weeks. This will help you catch them early and prevent them from becoming a major problem.

By following these tips, you can help to keep your black tank clear and flowing freely.
