How to Unclog an RV Toilet

Unclogging an RV toilet can be a messy but manageable task, and the best approach depends on the severity of the clog. Here are some methods you can try, starting with the simplest:

Basic methods:

  • Plunger: Try a standard toilet plunger (a flange plunger works best) with plenty of water in the bowl. If plunging doesn’t work, move on to other methods.
  • Hot water: If the clog is organic matter, carefully pour hot water (not boiling) into the bowl and let it sit for 30 minutes to an hour. Then, flush and see if the clog has cleared.

Chemical methods:

  • RV tank clearing liquid: Pour a specialized RV tank clearing liquid like “Clear-It” or “Enzyme Digest” into the toilet bowl and follow the instructions. These typically break down waste over a few hours to a day.
  • Baking soda and vinegar: Add 1/2 cup of baking soda followed by 1 cup of vinegar to the toilet bowl. The fizzing action might be enough to loosen the clog.

Mechanical methods:

  • Toilet snake: If the clog is deeper, use a flexible toilet snake designed for RV toilets. Insert it carefully into the bowl and try to reach and dislodge the clog.
  • PEX tubing: Use a long, flexible PEX pipe. Push it gently into the toilet bowl and wiggle it around to break up the clog. You can also attach it to a water hose for additional pressure.


  • Safety first: Always wear gloves and protective eyewear when dealing with RV waste.
  • Identify the system: Some RVs have direct-flush toilets, while others have piped systems. The approach may differ slightly.
  • Turn off valves: Close the freshwater supply and black tank valve before attempting any method.
  • Prevention is key: Use RV toilet paper and avoid flushing anything other than waste and approved products.

Remember, if none of these methods work, or if the clog is severe, it’s best to seek professional help from an RV technician. They will have the tools and expertise to handle the situation safely and effectively. Another article I wrote bout RVs that you will find very helpful is >>>> How to De-winterize Your RV?.

The Great Drain Heist: Confessions of a Clog Crusader (Part 1: The Scourge Strikes).

Alright, adventurers, listen up. We’ve all been there: nestled in nature’s embrace, campfire crackling, s’mores melting on eager tongues… then BOOM! The porcelain abyss overflows, threatening to engulf your glamping utopia in a tidal wave of fragrant despair. Fear not, intrepid travelers, for I, Captain Plunger, have battled Clogzilla countless times and emerged victorious. Today, I share my hard-won wisdom to ensure your throne remains a haven, not a hazardous waste zone.

Understanding the Enemy: Know Your Clog

Those porcelain blockades come in all shapes and sizes, each demanding a tailored takedown. Let’s crack the case:

Solid Waste Warriors: Leftover chili dogs, valiant but ill-advised adventures with corn on the cob (trust me, I’ve been there), and rogue avocado pits can form impassable fortresses.

Paper Pals Turn Traitors: Regular toilet paper might seem innocent, but those flimsy squares can clump up like rogue snowdrifts, especially in older or poorly maintained systems. Remember, RV-specific TP is your best friend!

Mineral Mischief: Hard water deposits, the bane of every RVer’s existence, can gradually build up, narrowing pathways and causing slow-drain misery.

Foreign Foes: Bottle caps, lost Lego bricks, rogue marshmallows (again, not my finest moment)… these unexpected intruders can wreak havoc on even the most robust plumbing.

Direct vs. Piped Peril: Knowing your RV’s plumbing layout is crucial. Direct-flush toilets send waste straight to the tank, while piped systems have additional twists and turns, potentially harboring hidden clogs.

Symptoms & Signs: The Clog Whisperer

Listen closely, for the toilet speaks (albeit in gurgles and groans). Here’s what it’s trying to tell you:

  • Slow drain: Your porcelain pal takes an age to clear the bowl. A minor clog might be brewing.
  • Gurgling symphony: Unsettling aquatic serenades emanating from the depths? Something’s blocking the flow.
  • Rising tide: The water level keeps inching higher after each flush. Prepare for a potential overflow situation.
  • The dreaded backup: This one needs no explanation. If your sink or shower starts sharing the toilet’s enthusiasm, it’s time for immediate action.

Remember, early detection is key! The sooner you tackle that clog, the less messy (and embarrassing) the battle will be.

Part 2: Arsenal of Awesomeness: Your Clog-Crushing Kit

Now, let’s arm ourselves for the inevitable showdown. Here’s your ultimate unclogging arsenal:

The Plunging Paladin:

  • Flange plunger: Your first line of defense. Fill the bowl with water, create a seal, and unleash a flurry of plunges. It’s rhythmic therapy with a plumbing purpose!
  • Hot water: For organic foes, a steaming assault can soften and break down the blockage. Just be careful not to crack your porcelain warrior.

Chemical Cavalry:

  • Enzyme digesters: These eco-friendly warriors break down waste over time, working their magic while you sip margaritas by the campfire.
  • Tank cleaning liquids: Think of them as napalm for clogs, dissolving even the most stubborn blockades. Follow the instructions carefully, though – these guys are potent!

The Snake Strikes Back:

  • Toilet snake: For deep-seated clogs, this flexible serpent slithers into the pipes, dislodging the enemy with its barbed tongue. Patience, my friends, is key when wielding this tool.
  • PEX tubing: This DIY hero, a long, thin pipe, can be snaked through the bowl to break up clogs or even attached to a water hose for some extra flushing power. MacGyver would be proud.

Remember, choose your weapon wisely! Not every clog deserves a chemical apocalypse. Start with gentle methods and escalate if necessary.

In Part 2, we’ll delve deeper into these tools and unlock more advanced techniques for even the most formidable clogs. Stay tuned, brave adventurers and your porcelain throne shall remain a bastion of hygiene and happiness!

Part 3: The Chronicles of Clog Conquest: True Tales of Triumph and Tribulation.

Alright, warriors, strap yourselves in. It’s time for Captain Plunger to regale you with tales of epic battles won and hilarious blunders avoided (mostly). Gather ’round the digital campfire and learn from the scars of my porcelain wars:

The Case of the Chili Dog Catastrophe: Picture this: Yosemite National Park, sunset hues painting the granite cliffs, and a perfectly grilled chili dog in my eager grasp. One enthusiastic bite later, disaster struck. The mighty frankfurter, a victim of its deliciousness, lodged itself firmly in the plumbing abyss.

Panic bubbled, but Captain Plunger knew what to do. Armed with the trusty flange plunger and a mantra of rhythmic grunts, I attacked. After a valiant struggle, the chili dog yielded, emerging in a triumphant arc worthy of a slow-motion replay. Victory tasted sweet, though slightly spiced.

The Ballad of the Mineral Monster: Ah, the insidious menace of hard water deposits. In the depths of Zion National Park, my toilet began a mournful gurgling opera, hinting at a deeper issue. Armed with a vinegar and baking soda concoction (think science fair volcano, minus the eruption), I poured the fizzy elixir down the drain.

The bubbles gurgled back, a temporary victory dance. But patience, fellow adventurers, is key. Over the next few hours, the mineral villain crumbled, vanquished by the power of chemistry. The lesson? Regular demineralization rituals are your friend, especially in hard-water regions.

The Legend of the Lost Lego: Picture this: Yellowstone National Park, geysers erupting, and my daughter gleefully constructing a Lego masterpiece… right next to the open toilet. One misplaced brick later, the porcelain throne became a Lego landfill. Horror seized me, but Captain Plunger remembered the PEX tubing hero.

With gentle maneuvering, I snaked the plastic villain out, restoring peace and harmony to the bathroom (and averting a full-blown tantrum meltdown). Remember, vigilance is key! Keep those tiny toys firmly in their designated zones.

These are but a few tales from the vast library of clog confrontations. Each battle teaches us valuable lessons: patience, resourcefulness, and the importance of choosing the right tool for the job. And don’t be afraid to laugh at yourself when things go awry – sometimes, a good plumbing blunder is the best campfire story!

Part 4: Beyond the Bowl: Maintaining Plumbing Peace.

Clog-conquering heroes, rejoice! But our quest doesn’t end at the porcelain battlefield. To ensure long-term plumbing peace, we must become masters of preventative maintenance:

The Art of the Empty Tank: Regular tank emptying is your holy grail. Choose designated dump stations wisely, consider portable tanks for boondocking trips, and invest in a quality sewer hose. Remember, a full tank is a ticking time bomb for potential overflows and clogs.

Sensor Savvy: Embrace the magic of tank sensors. These digital oracles warn you of impending tank fullness, preventing messy surprises. Learn to interpret their readings and empty them accordingly.

Seasonal Rituals: Winterizing and de-winterizing your RV are crucial for plumbing health. Follow proper procedures to avoid frozen pipes and cracked tanks. Think of it as a seasonal plumbing spa treatment.

RV-Specific Supplies: Ditch the flimsy, clog-prone household essentials. Invest in RV-specific toilet paper, waste tank treatments, and cleaning products. Your plumbing will thank you (and you’ll thank yourself for avoiding another chili dog incident).

By incorporating these habits, you’ll transform from clog conqueror to plumbing peacekeeper. Remember, prevention is a thousand plunges worth!

Go forth, adventurers, and may your RV toilets forever flow freely!

V. Beyond the Drain: Unexpected Heroes and DIY Hacks.

Alright, champions, we’ve covered the usual clog suspects and preventative measures. However, the battlefield of RV plumbing demands flexibility and resourcefulness. Sometimes, you need to think outside the plunger! Here are some unconventional allies and DIY tricks to keep your throne squeaky clean:

The Plunger Posse:

  • Dish soap: A few squirts of trusty dish soap can lubricate the path for stubborn clogs, especially when combined with plunging. Just remember, don’t overdo it, or you’ll be dealing with sudden chaos!
  • Wet/dry vacuum: This versatile friend can suck up minor blockages or pull out debris lurking beyond the plunger’s reach. Just make sure the vacuum is rated for wet materials and use caution when dealing with liquids.
  • Baking soda and vinegar combo: This fizzy duo isn’t just for science projects. Pouring baking soda followed by vinegar creates a gentle bubbling action that can break down organic clogs, especially in the early stages.

DIY MacGyver Moments:

  • The coat hanger hook: Bent into a J-shape, this trusty tool can snag paper or fabric clogs lurking near the drain opening. Just be careful not to scratch the porcelain.
  • The plastic bottle plunger: Cut the bottom off a sturdy plastic bottle, attach a stick for leverage, and voila! You’ve got a makeshift plunger for those times when the real deal is MIA.
  • The hot water trick: For minor grease build-up, carefully pour hot (not boiling) water down the drain. The heat can help melt the grease, allowing it to flow through. Just avoid this method with plastic pipes, as it could cause warping.

Remember, these are last-ditch efforts before calling in the pros. But with a little ingenuity, you can often turn everyday items into clog-conquering heroes. Just be extra cautious and avoid any methods that might damage your plumbing.
