Black Tank Myths Debunked: What Every RVer Needs to Know

Black Tank Myths Debunked: What Every RVer Needs to Know

Posted by Camco on May 16th 2025

If you’re an RV enthusiast, you’ve probably heard all kinds of “expert tips” about managing your black tank. From skipping toilet chemicals to throwing in ice, the myths can be as plentiful as they are confusing. Luckily, black tank maintenance doesn’t have to be complicated or mysterious. With the right routine and tools, it’s just another part of RV life.

Here, we’re breaking down common black tank myths, busting them with the facts, and sharing some game-changing products to make your life easier.

Myth #1: “You Don’t Need Toilet Chemicals—Just Use Lots of Water.”

- The Claim: Water alone will keep your tank clean and eliminate odors, so there’s no need to invest in toilet chemicals.

- The Truth: While water is essential, it’s not enough on its own. Think of it like your home plumbing—you wouldn’t just flush water down the drain and expect it to clean itself, right? Without proper treatment, waste can build up, leading to clogs and foul odors (especially in hot weather or on longer trips).

That’s where effective black tank treatments, like Camco’s TST Pro, comes in. TST Pro’s breakthrough enzyme formula breaks down waste and controls odors at the source. Used regularly, it keeps your tank clean and smelling fresh.

  • Pro Tip: For best results, pair TST Pro with plenty of water. This combo prevents waste buildup, fights odors, and makes dumping a breeze.

Myth #2: “Tossing Ice Into Your RV Black Tank Will Clean It.”

- The Claim: Throwing a bag of ice in your black water tank while driving will scrub its walls clean.

- The Truth: It sounds clever, but it doesn’t live up to the hype. While ice might help knock loose a bit of light residue, it’s far from a reliable cleaning method. RV holding tanks aren’t built for physical scrubbing inside, so this trick is more of a gimmick than a real solution.

For a thorough clean, try the Rhino Blaster Pro. This innovative product connects to your RV’s sewer outlet and flushes the tank with powerful water blasts. It even has a clear elbow, so you can see when your tank is clean.

  • Pro Tip: Use the Rhino Blaster Pro regularly, especially after longer trips to prevent buildup and odors. Pair it with TST Pro for the ultimate cleaning and odor-fighting combination.

Myth #3: “Black Tanks Are a Nightmare to Maintain.”

- The Claim: Black tanks are messy, difficult, and just plain gross to manage.

- The Truth: Sure, dealing with your RV black water tank isn’t anyone’s favorite chore, but it’s far from a nightmare. Once you get into a routine, it’s simple. The key is to be proactive, not reactive. Flushing your tank thoroughly after each dump, avoiding non-biodegradable items (looking at you, wet wipes!), and using quality treatments like TST Pro can save tons of trouble.

Want even less stress? Add camping tools like the Sidewinder Sewer Hose Support or the Rhino Nesting RV Sewer Hose Support Kit to your camping supplies. These sturdy, easy-to-use sewer hose holders keep your hose elevated and aligned, ensuring a smooth flow while emptying your tank.

  • Pro Tip: Take your sanitation game to the next level with the Rhino Ultimate Sewer Hose Kit. This all-in-one solution comes with 11 essential pieces, making black tank maintenance easier than ever.

Myth #4: “Black Tanks Always Smell Awful.”

- The Claim: Nasty black tank smells are just part of the RV experience.

- The Truth: Persistent odors happen when maintenance isn’t up to par. But with the right care, you can keep those smells in check.

Here’s how to tackle odors like a pro:

  1. Deep clean your tank: Use tools like the Rhino Blaster Pro or Camco Flexible Swivel Stik to flush out lingering waste and sludge.
  2. Use high-quality treatments: RV black tank treatments, like TST Pro, eliminate odors by breaking down waste effectively. Say goodbye to cheap treatments that just mask the smell.
  3. Check your seals: Faulty toilet or valve seals are often the culprits behind unpleasant smells. Make sure they’re intact and functioning.
  • Pro Tip: Good ventilation is your friend! Ensure your roof vent is working to help odors escape instead of lingering inside your camper.

Myth #5: “Regular Toilet Paper Works Fine in an RV.”

- The Claim: There’s no need to buy RV-specific toilet paper because regular household TP works just as well.

- The Truth: Some household toilet papers claim to be “septic-safe,” but many don’t break down quickly enough for black tanks. Using the wrong type of toilet paper can lead to clogs and tough-to-clear messes.

RV-specific toilet tissue is designed to dissolve fast with minimal water. Products like Camco RV Toilet Tissue keep your system running smoothly, hassle-free.

  • Pro Tip: Even with RV-safe toilet paper, more water is always the answer. A hydrated black tank is a happy black tank!

Myth #6: “Always Keep the Black Tank Valve Open to Prevent Overflows.”

- The Claim: When you’re hooked up to a sewer at a campsite, leaving the black tank valve open prevents overflows.

- The Truth: This is a recipe for the dreaded “poop pyramid.” When liquids drain away, solid waste stays behind, eventually forming a dried-out, hard-to-remove mess.

Instead, keep the valve closed and allow waste to accumulate in a well-hydrated tank. Dump everything at once for a strong, thorough flush. You can use the Rhino Blaster Pro to ensure your tank is completely cleared each time.

  • Pro Tip: To avoid black tank issues, always dump with plenty of water. It’s worth the effort.

The Bottom Line: Stress-Free Black Tank Maintenance Starts with the Right Tools

Black tank care doesn’t have to be gross or complicated. Bust the myths, stick to smart practices, and let the right tools do the heavy lifting.

With the best tools, staying fresh is simple, so you can savor every adventure.
