If you’ve spent any time RVing, you already know the black tank is the one topic nobody wants to talk about — until something goes wrong. For me, “something going wrong” meant noticing that no matter how many times I flushed my tank, the smell never fully went away. After some digging, I realized my tank wasn’t actually getting clean between dumps. That’s what finally pushed me to write this Camco Swivel Stik black tank rinser review — because the fix was simpler than I ever expected.
We’d been full-timing in our Class C for about two years at that point. I thought I was doing everything right: using tank treatments, flushing with plenty of water, and dumping regularly. Still, that lingering odor kept coming back. My husband suggested we might have buildup on the walls of the tank itself — not just waste sitting at the bottom. That idea sent me down a rabbit hole of RV forums and YouTube videos at 11 p.m. on a Tuesday.
What I kept seeing recommended, over and over, was a dedicated tank rinsing wand. Specifically, people kept mentioning the Camco. So I decided to give it a real shot and document exactly what happened.
Why I Chose the Camco Swivel Stik Over Other Options
Honestly, my first instinct was to grab whatever was cheapest. There are a lot of these wands on Amazon, ranging from budget plastic sticks to stainless steel options with fancy attachments. But after reading through dozens of reviews, a few things kept pointing me toward the Camco RV Holding Tank Swivel Stik Rinser.
First, Camco is a brand I already trusted. We use their sewer hoses, water pressure regulators, and leveling blocks. They’re not the flashiest brand in the RV world, but their stuff tends to be reliable and widely available. Second, the rotating spray head design made a lot of sense to me. A fixed-spray wand can only hit what it’s pointed at directly. A swivel head, in theory, can reach wall surfaces and corners that a straight stream would miss.
Third — and I’ll be honest here — the price point was reasonable. At the time I bought it, it was around $20. For a potential fix to a problem that had been bothering me for months, that felt like a very low-risk experiment. I also liked that it came in at 34 inches of flexible reach, which seemed long enough to get past the toilet and into the tank itself without being so unwieldy that I’d dread using it.
First Impressions Out of the Box
The Camco RV Holding Tank Swivel Stik Rinser (model 40074) arrived in simple packaging — nothing fancy, just a cardboard sleeve with product info printed on it. The wand itself is plastic, which I expected at this price. It’s a light tan/beige color, which is very much a “functional tool, not a showpiece” vibe.
My first thought was that it felt lighter than I expected. Not flimsy, exactly — more like it was designed to be easy to handle rather than heavy-duty. The 1/4-turn shutoff valve near the handle clicked on and off with a satisfying snap, which I appreciated. There’s nothing worse than a valve that feels mushy or uncertain when you’re working with a black tank.
The ergonomic grip felt comfortable in my hand, even with gloves on (always wear gloves for this job — I cannot stress this enough). The flexible midsection of the wand bent easily but held its shape once positioned. Overall, first impressions were solid. Nothing about it screamed “premium,” but nothing felt like it was going to break on first use either.
What’s Included
- The Swivel Stik wand itself (34 inches with flexible reach)
- Standard garden hose fitting at the water inlet end
- 1/4-turn shutoff valve integrated near the handle
- Rotating spray head at the business end
No instructions were included — but setup is genuinely intuitive. You connect your hose, insert the wand into the toilet, turn on the water, and go. There’s not much more to it.
My Testing Protocol: How I Actually Used It
I tested this over the course of about three months, across multiple dump station visits. Here’s roughly how my routine looked each time.
After dumping the black tank completely at the dump station, I’d stay connected to the sewer. Then I’d connect the Swivel Stik to our designated “black tank only” hose (a short section I keep separate from the freshwater gear — please do the same). With the wand inserted through the toilet and the tank valve still open, I’d turn on the water and let the rotating head do its thing for about 3 to 5 minutes.
I could hear and feel the water pressure changing as the spray head rotated. The idea is that it’s hitting the walls at different angles continuously. After a few minutes, I’d close the dump valve, let the tank fill partially with water, then re-open and dump again. Watching what came out that second time was… educational. Let’s leave it at that.
Some visits, I did this two-flush cycle twice before I felt satisfied. Occasionally I’d add a tank treatment enzyme product after the final rinse and before we drove to our next site. The whole process added maybe 10 to 15 minutes to my dump routine — totally worth it in my opinion.
What Actually Changed After Using It
I want to be straightforward here: I was skeptical after the first use. The smell improved slightly, but I wasn’t blown away. I remember thinking, “Did I just spend $20 on something I’ll use twice and then forget about?” That moment of doubt was real.
By the third use, though, something had clearly shifted. The persistent background odor that I’d basically accepted as part of RV life was noticeably reduced. Not completely gone — but significantly better. By the end of month two, our bathroom smelled like an actual bathroom rather than a sewer-adjacent space.
Specific Improvements I Noticed
- Reduced odor inside the RV between dump days
- Less visible residue during subsequent rinse cycles
- Tank sensor readings became more accurate over time (this is a common side effect of a cleaner tank)
- Overall confidence that the tank was actually getting clean, not just drained
The sensor accuracy improvement was honestly a surprise bonus. If you’ve ever had a black tank sensor that perpetually read “full” even after dumping, you know how annoying that is. Ours had done that for months. After consistent rinsing with the Swivel Stik, it started reading more realistically. I can’t say for certain that was the only factor, but the timing lined up.
The rotary cleaning action does seem to make a real difference compared to just filling and flushing the tank with water alone. The spray reaches areas that passive fill-and-dump simply can’t address. I noticed this most clearly when I could see the rinse water running cleaner after fewer cycles than before.
The Downsides: What I Didn’t Love
No review is complete without honest negatives. Here’s what I’d flag for anyone considering this purchase.
It’s all plastic. The wand holds up fine under normal use, but I wouldn’t call it rugged. If you dropped it onto concrete at the wrong angle, I’d expect it to crack. After three months, mine still looks fine — but I treat it carefully.
Water pressure matters. The rotating spray head works best with decent water pressure. At some campground hookups, pressure is lower than ideal. The head still spins, but noticeably slower. Results were slightly less impressive at low-pressure sites. Using a water pressure regulator that allows a higher flow helped, but it’s worth knowing.
It requires you to stay at the dump station longer. If you’re at a busy dump station with a line forming behind you, the multi-cycle rinsing process can feel awkward. This isn’t a wand issue specifically — it’s just the reality of doing a thorough job. Plan accordingly.
No storage solution included. After use, you need to rinse it thoroughly and store it somewhere. Camco doesn’t include a bag or case. I ended up buying a cheap zip-close bag to keep it contained in our wet bay.
Final Verdict: Camco Swivel Stik Black Tank Rinser Review
After three months of consistent use, my honest conclusion is this: the Camco RV Holding Tank Swivel Stik Rinser does exactly what it claims to do. It’s not glamorous, it’s not high-tech, and it’s made of plastic. But it solves a real problem at a low price, and it holds up with regular use.
Buy It If:
- You notice persistent black tank odors that don’t resolve with treatments alone
- Your tank sensors give inaccurate readings
- You’re a full-timer or frequent dumper who wants a thorough clean
- You’re looking for an affordable entry-level solution to tank maintenance
Skip It If:
- You need something heavy-duty and prefer stainless steel construction
- Your RV already has a built-in tank flush system that works well
- You consistently deal with very low campground water pressure
For most RVers dealing with a smelly or sensor-challenged black tank, the roughly $20 price point makes this a genuinely low-risk purchase. I’d recommend it without hesitation as a first step before spending more on fancier solutions.
A Note on the Alternative: Frebuta RV Black Tank Cleaner Wand
If you want something more durable, it’s worth looking at the Frebuta RV Black Tank Cleaner Wand. It’s a 62-inch stainless steel option that offers significantly more reach and a more robust build. The extra length could be useful for larger holding tanks or different RV toilet configurations. At a higher price point, it’s better suited for full-timers who want a tool built to last for years rather than seasons. I haven’t personally tested the Frebuta long-term, so I won’t make a direct head-to-head comparison — but it’s a legitimate option worth considering if the plastic construction of the Camco gives you pause.
For my needs — and likely for most weekend warriors and part-time RVers — the Camco hits the sweet spot of effective, affordable, and simple. That’s a combination that’s genuinely hard to beat.
