How to Unclog a Camper Toilet

Are you desperate for a solution for how to unclog a camper toilet and save your vacation? Thankfully, unclogging a camper toilet isn’t complicated and is usually achievable with a few basic supplies.

Taking a trip in your camper is a fun way to see the sights and spend time with your family and friends. Yet your camper vacation becomes a nightmare if the toilet gets blocked. The design of RV toilets makes them more prone to clogging than regular ones. Feces and toilet paper buildup in the drain pipe and black water tank, leading to standing water. In severe cases, this could even result in a black water leak inside your RV.

Tackle a blocked camper toilet as soon as you notice it before the issue worsens. Don’t waste money on expensive and dangerous toilet drain openers. Follow our simple guide for how to clear a clogged RV toilet drain to take care of the problem.

How to Clear a Clogged RV Toilet Drain Fast

When there’s an issue in the bathroom, you must know how to unclog a camper toilet quickly. The plumbing inside a camper is simple but smaller than the pipes inside the house. This, plus how the system works, increases the likelihood of blockages.

Luckily, a blocked RV toilet doesn’t have to mean the end of your trip. Explore techniques for unclogging a camper toilet with an air wand, a plunger, boiling water, ice cubes, dish soap, a drain snake, baking soda and vinegar, laundry detergent, commercial cleaners, and tank treatments.

How Does a Camper Toilet Work?

Toilets for campers are portable but robust as they have to survive the bouncing while traveling. The toilet drains into an RV toilet holding tank, much like a home running on a septic tank. This holding tank is emptied periodically from the outside after waste has accumulated in it.

There are three separate water tanks included in travel trailers. The water used in the kitchen and bathrooms sits in the freshwater tank. Water drains from the kitchen and bathroom sinks and goes into the gray water tank. The toilet waste goes to the black water tank. These tanks come in various sizes depending on the size of the trailer. Each gray and black water tank typically holds an average of 37 gallons.

Flushing an RV Toilet

In contrast to a toilet in a building, an RV toilet includes a pedal beneath the bowl. Freshwater rushes into the toilet, and a flap at the bottom of the bowl opens when this pedal is depressed. The waste travels down the sewer line to the black water tank. When the pedal is released, the flap closes, preventing odor from leaking inside the camper.

The gray and black water tanks need to be emptied every few days. The number of individuals using the restroom determines the frequency. The waste tanks should be empty before setting out for a trip. Full tanks make the RV heavier and reduce fuel efficiency. Most campgrounds feature dump stations, often known as sanitation stations. Under the camper are valves for the gray and black water tanks, with a connecting point for a hose to take waste to the dump station.

Why Does RV Plumbing Clog?

The water tank system on which RV toilets run predisposes them to clog more than a conventional toilet inside a building. Solid waste builds up in the black water tank to form something referred to as a poop pyramid.

Tissue paper and feces accumulate to form a pyramid-like structure, which doesn’t empty through the sewer hose at the dump station and causes clogging. As the toilet is flushed more, the solid waste backs up through the drain line until the water in the toilet bowl can’t go down.

The poop pyramid phenomenon, combined with the wrong kinds of toilet paper, not flushing often enough, and not emptying frequently, leave your camper toilet at a high risk of becoming blocked.

How to Unclog a Camper Toilet With an Air Wand

An air wand is a convenient tool for unclogging everything from your RV toilet to your kitchen sink. Unlike a conventional plunger, an air wand takes the labor and physical strain out of eliminating blockages from a pipe.

The tool has a slim rod and an end cap that fits easily into the drain. When deployed, the end cap releases a strong gust of air, which forcibly breaks up the clog; this reopens your toilet drain. Use the wand following the manufacturer’s instructions and ensure it’s safe for your RV toilet before getting rid of the clog.

Unclogging a Camper Toilet Using a Plunger

Most of us reach for a plunger to fix the blocked toilet in our bathroom, and this time-tested tool works just as well in your camper. A plunger has a rubber suction cup with a handle. The suction cup is fitted over the toilet drain and depressed repeatedly to force movement inside the pipe and clear the clogged toilet.

Wear gloves, and inspect the inside of your RV toilet bowl. You may have to hold down the flusher to lift the flap and reveal the drain opening. Place the plunger securely over the drain opening and push on the handle until the cup flattens. Pull the handle back up so the cup returns to a dome shape, and repeat this procedure several times. Test the patency of your toilet and continue plunging until the blockage is gone, or try a different method.

Boiling Water for Clearing a Clogged RV Toilet Drain

Sometimes boiling hot water is sufficient to clear the blockage from your toilet. The heat breaks down the feces and grime, separating and moving it through the drain pipe into the black water tank.

Boil a medium pot of water or use an electric kettle. Wear heatproof gloves to protect your hands and arms, and be aware that the boiling water could spill or splash back. Slowly pour the entire water kettle down your toilet and leave it for at least 20 minutes. Check if your drain is open. If the clog is still intact, try another kettle of boiling water. If this doesn’t work, use an alternative cleaning technique.

Ice Cubes Help to Remove a Block in a Travel Trailer Toilet

The ice cube method is a simple remedy. Since RV toilets use little water when flushing, additional water helps clear them of clogs. The ice also applies pressure to break up obstructions, and campgrounds have it available.

Put one or two bags of ice in the black tank and toilet. Close the toilet lid and valves and drive your RV a short distance. The movement agitates the ice in the pipes, where it melts and facilitates passing the clog through the lines. The ice should soften and loosen the obstructions within half an hour of driving.

Dish Soap Cleans Your RV Drain

We keep dish soap on hand in our kitchen at home or in our RV. If you have this staple, you have an effective way to unclog your camper toilet. Dish soap contains heavy-duty detergents and surfactants that break down the stubborn organic mess. Since feces is an organic material, dish soap dissolves it to eliminate clogging.

Pour one cup of liquid dish soap and four cups of very hot water down your toilet and wait an hour. Flush the toilet to check if the drain is open, and repeat the process if necessary.

A Drain Snake Eliminates a Toilet or Sewer Hose Blockage

A drain snake or toilet drain auger is a familiar tool to unclog regular toilets. It also works for a camper toilet. A toilet snake has a long piece of wire and a rotating handle. Insert the end of the wire into your toilet bowl and turn the handle to move it through the pipes slowly. Once you encounter the blockage, keep winding the snake to skewer the end into the clog and reel it in to bring it up and out of the drain.

Baking Soda and Vinegar Unclog RV Toilet Pipes

Baking soda and distilled white vinegar are famous for their many uses. Both have applications in cooking and cleaning, and one of their lesser-known talents is unclogging toilets.

Baking soda and white vinegar combine in a fizzing reaction, which loosens stubborn blockages and opens your RV drain pipe. Avoid bringing toxic and dangerous drain openers into your camper. Use this cheap and natural fix to get the block out of your toilet.

Put on the rubber gloves and carefully pour the entire box of baking soda into your camper toilet. Follow this with four cups of undiluted distilled white vinegar. Push the flush pedal and open the flap so they travel down the drain, and leave the baking soda and white vinegar in the toilet for at least ten minutes. Check if your toilet drain is open; if not, use a different cleaning procedure.

Laundry Detergent for Toilet Blocks

When traveling, it’s tough to find cleaners and tools to help unclog your RV toilet. Laundry detergent works in a pinch as it contains detergent, much like dish soap.

Pour half a cup of laundry detergent and two cups of warm water into your RV toilet, and open the flap so they enter the drain pipe. Leave the laundry detergent in the line for at least half an hour before flushing to see if the clog is gone. If the obstruction remains, use more laundry detergent and water.

Commercial Cleaners to Unplug the Drains in an RV Bathroom

If you’re on the road with limited supplies or would rather use a store-bought cleaner, head to your local camping or hardware store. There’s a huge selection of toilet cleaners and drain openers, but choosing one safe for an RV system is crucial. Read the instructions on the drain opener carefully and use it under the directions. Heed any safety guidelines as you unclog your toilet.

Treat Your Black Water Tank

Get ahead of blockages by using an RV holding tank cleaner at least once every six months and treatment for solid waste. Even if you empty your tank following every use, you might not get everything. Feces tend to collect in the center of the holding tank and don’t always drain out through the hose.

A tank treatment breaks down fecal matter into a liquid to ensure your tank drains thoroughly. Treating your RV black water tank helps stop the formation of a feces pyramid and reduces the likelihood of clogging.

The Correct Paper Prevents an RV Toilet Clog

Inappropriate toilet paper builds up in your RV tank and increases incidences of clogging. While household toilets work well with most toilet paper brands, the right paper helps keep your RV toilet running. RV toilet paper breaks up quickly and has less bulk, so it passes through pipes smoothly. Choose a septic-safe single-ply RV toilet paper. Use the toilet roll sparingly and flush after each use to avoid clogged RV toilets.

Keep Your Black Tank Valve Closed

A common mistake many new camper owners make is leaving their RV black tank outlet open when it’s empty. Always keep your valve closed, even if there’s no waste in the tank. Allowing air and other debris into the chamber can make your black tank flush process less effective and predispose your system to blockages. Check that your valve cap is securely in place before setting out, and carefully reinstall it after emptying your black water at the dump station.
