How To Unclog an RV Camper Toilet

Clogged toilets can be an inevitable hassle in an RV camper, disrupting the convenience and mobility that come with the RV lifestyle. Whether due to excess toilet paper, solid waste, or other unforeseen issues, an obstruction can quickly turn a cozy camper into an uncomfortable situation.

The process of unclogging an RV toilet involves using specific methods and tools designed for the nuances of RV plumbing systems. While the approach may be similar to that of residential toilets, RV toilets connect to a black water holding tank, a feature that necessitates unique maintenance practices to prevent future clogs.

Keeping an RV toilet functioning properly not only requires understanding the unclogging process but also acquiring preventative maintenance tips to keep your plumbing in top-notch shape.

Materials Needed

Before embarking on the quest to unclog your RV camper toilet, gathering the right materials is paramount. Each tool serves a unique purpose and employs a method suited to varying types of clogs. From manual efforts to chemical assistance, be prepared to tackle the issue head-on with these essentials.


A must-have in any RV, plungers create a vacuum seal around the toilet drain, enabling you to dislodge clogs by pushing and pulling the handle.

  • Standard plunger: Ideal for minor clogs close to the toilet bowl's surface.
  • Accordion plunger: Offers more force for stubborn clogs but may need careful handling to prevent toilet damage.

Hot Water

The hot water method can be effective for dissolving organic matter causing the blockage. Slowly pour a bucket of hot (not boiling) water into the toilet bowl to help break down the clog.

  • Kettle or pot: To heat water on your RV stove.
  • Bucket or large jug: To transport and pour the heated water.

Dish Soap

Lubricating the toilet with dish soap can ease the clog's passage through the plumbing. A generous squirt of liquid dish soap into the bowl may do the trick.

  • Dilute with hot water to enhance penetration.
  • Let sit for 10-15 minutes before attempting to plunge again.

Enzyme-Based Cleaner

Opt for enzyme-based cleaners to naturally break down waste without harming RV plumbing systems.

  • Biodegradable and safe: Avoids damaging septic systems.
  • Pre-measured packs: For convenient and proper dosing.

Flexible Toilet Auger

A toilet auger extends a flexible cable into the toilet to physically break up clogs unreachable by a plunger.

  • Rubber sleeve: To protect the porcelain from scratches.
  • Crank handle: To extend and retract the cable with precision.

Here’s a table with the essential checklist for unclogging your RV camper toilet:

Material Purpose Note
Plunger Dislodges close clogs Choose a type suitable for your RV toilet
Hot Water Dissolves organic clogs Use with care to avoid burns
Dish Soap Lubricates clog passage Combine with hot water for effectiveness
Enzyme-Based Cleaner Naturally breaks down waste Safe for regular maintenance
Flexible Toilet Auger Physically clears out deep clogs Ensure it's RV-safe to avoid damage

Steps for Unclogging Your RV Camper Toilet

Trouble with your RV toilet? Let's take on that stubborn clog with some tried-and-true tactics.

Identify The Type of Clog

Diagnosing the clog is critical. Solid waste build-up often leads to clogs, while non-flushable items can create more complex blockages.

Use a Plunger Vigorously

A good old-fashioned plunger can be quite effective, especially with recent clogs. Make sure there's enough water in the bowl to form a seal around the plunger for maximum pressure.

Pour Hot Water and Dish Soap Into the Toilet

Hot water combined with dish soap can break down greasy waste. Avoid using boiling water as this may damage your toilet's seals.

Allow The Mixture to Sit for Several Minutes

Patience is key. Give the soap and water mixture time to work its way through the clog before trying to flush.

Apply an Enzyme-Based Cleaner If Needed

Enzyme-based cleaners are excellent for dissolving organic matter without damaging plumbing components. Follow the product's instructions for the best results.

Use a Flexible Toilet Auger for Tough Clogs

A toilet auger, also known as a snake, can dislodge clogs that plungers can't. Carefully manoeuvre the auger to avoid scratching the toilet bowl.

Flush The Toilet to Check If the Clog Is Cleared

Once you believe the clog is dealt with, flush the toilet to see if the water drains smoothly. If it doesn't, you may need to repeat the process or consider other methods, such as the ice cube method, or seek a professional plumber's assistance.

Here’s a table showing clogging types and their initial actions:

Clog Type Initial Action
Solid waste Plunger, Enzyme Cleaner
Non-flushable items Auger, Professional Assistance
Greasy build-up Hot Water, Dish Soap

  • Press and hold the foot pedal or flush lever to allow complete flushing.


  • Prevents waste buildup
  • Reduces smells


  • Uses more water

  • Prevents scratches


  • May require more elbow grease
  • Could be less effective on tough stains

Frequently Asked Questions

Encountering a clogged RV toilet can be a frustrating experience for any camper. Addressing some of the most common inquiries can prepare RV owners for dealing with such scenarios efficiently.

Can hot water help in dealing with a clogged RV toilet?

Hot water can sometimes loosen a clog in an RV toilet by breaking down the waste matter. Pouring a gallon of boiling water directly into the toilet bowl might dissolve the blockage. However, take care to pour slowly to avoid splashing and damaging the toilet's seals.

Is it feasible to use a standard plunger for an RV toilet blockage?

Yes, a standard plunger can often be used to unclog an RV toilet just as it would for a residential toilet. The suction action created by the plunger can dislodge the clog and restore proper flushing. Ensure the plunger fully covers the toilet's outlet for maximum effect.

What steps should I take if my RV toilet's water won't go down?

If the water in your RV toilet isn't going down, first close the black tank valve to prevent any more water from entering the tank. Then, use a plunger or a flexible toilet auger to attempt to dislodge the clog. If these tools are unavailable, you might consider using hot water or a chemical de-clogger designed for RV use.

In the absence of a plunger, what alternatives are available to unclog a camper toilet?

Without a plunger, there are a few methods to unclog a camper toilet. You can pour hot water, use a DIY mix of vinegar and baking soda, or utilize a chemical clog remover. Some RV owners also use a wet/dry vac to suck the clog out of the toilet.

How can a toilet snake be effectively used to clear an RV toilet clog?

A toilet snake or closet auger can be threaded through the toilet to reach and break up the clog. Insert the snake into the toilet bowl's outlet and slowly turn the handle to extend the coil. When you feel resistance, you've likely reached the clog; keep turning to break it apart.

What's the best approach to unclogging a stubborn RV toilet holding tank?

For a stubborn clog in the holding tank, it's advisable to try a holding tank cleaner or a mixture of ice cubes and water, which can break up the debris when you drive the RV around. If these methods fail, professional assistance may be required to ensure the holding tank is properly cleared without damage.
