Camco Rhino Drain Lock Review 

Introduction

If you’ve RVed for any amount of time, you know that dealing with sewer hookups isn’t exactly the most glamorous part of camping. It’s one of those necessary chores that can either go smoothly or turn into a frustrating, messy hassle. 

Over the years, we’ve tried different adapters and setups, but many of them have either felt flimsy, leaked odors, or required too much time to attach securely.

That’s why we were excited to try out the Camco Rhino Drain Lock, and honestly, it has been a game-changer for us. We’ve been using it regularly, and it’s made our setup and breakdown process noticeably easier and faster. 

The connection feels more secure than the traditional screw-on elbows we used before, and it doesn’t take nearly as much effort to get on and off. Plus, its flexible sizing has worked with every dump station we’ve come across so far.

In this review, we’ll share our experience with the Camco Rhino Drain Lock, break down its features, and highlight what other RVers are saying. By the end, you’ll know if it’s a worthwhile upgrade for your RV setup.

What is the Camco Rhino Drain Lock?

The Camco Rhino Drain Lock is an upgrade to the traditional RV sewer elbow. Instead of the old screw-on style that requires threading it into place (and sometimes fighting with crooked or worn-out connections), this adapter uses a secure locking mechanism with an easy-to-grip handle.

It’s designed with a 3-in-1 adapter, which means it fits a variety of dump station inlet sizes. That flexibility alone makes it worthwhile because not every campground has the same setup, and in the past we’ve had to wrestle with mismatched fittings or carry extra adapters “just in case.”

What really sets this adapter apart is its odor-tight seal. Sewer hookups aren’t something you want to smell while you’re enjoying your site, and this lock gives us peace of mind that once it’s in place, it’s sealed securely.

In short, the Rhino Drain Lock is Camco’s solution to one of RVing’s least-enjoyable tasks: keeping your sewer connection simple, clean, and reliable.

Key Features & Benefits

After using the Rhino Drain Lock on multiple trips, here are the features that stand out the most to us and why they matter:

1. Effortless, Odor-Tight Dumping
This is our biggest win. Once the adapter is locked in, it creates a tight seal that prevents odors from escaping. With older screw-on elbows, we always worried about leaks or odors escaping. With this, we can hook up and not think twice.

2. Easy-to-Use Handle
The built-in handle makes connecting and disconnecting so much simpler. Instead of twisting or wrestling with threads, it’s a smooth push-and-lock action. During breakdown, it’s just as easy to remove, which is especially lovely when you’re trying to pack up quickly.

3. Versatile 3-in-1 Adapter
One of the biggest headaches in RVing is inconsistent campground sewer hookups. Some are perfectly standard, others are cracked, crooked, or a completely different size. The 3-in-1 design has given us flexibility at every dump station so far. It’s nice not having to dig around for extra adapters.

4. Secure & Reliable Fit
Compared to screw-on elbows, the Rhino feels more solid once it’s in place. We’ve noticed less “wiggle” and no need to prop it up with rocks or weights (yes, we’ve had to do that before!). Knowing it’s not going to slip out mid-dump is peace of mind we’re happy to pay for.

5. Quick Setup & Breakdown
Probably our favorite part: it’s faster. Hookups are one of those tasks we want to spend as little time on as possible, and this adapter saves us a few minutes every time. When you’re traveling often, that adds up.

Our Experience Using the Drain Lock

From the very first time we hooked up the Camco Rhino Drain Lock, we noticed how much smoother the process was compared to our old screw-on adapters. Instead of crouching down, lining up threads, and twisting until our shoulders hurt, it was as simple as locking it into place. It felt snug and secure without us having to force it.

On trips, we’ve used it at several different campgrounds, some with newer hookups and some with worn-out or oddly shaped drains. In every case, the Rhino has sealed up tight. With older setups, where we used to pile rocks or weights on top of our elbow to keep it from slipping, this adapter stayed put without any extra “campground hacks.”

What surprised us most was how much easier it made breaking down the RV. After a long trip, the last thing you want to do is fight with sewer connections. With the handle, it comes off quickly and cleanly, allowing us to move on without worrying about lingering smells or messy leaks.

Overall, it’s made the least glamorous part of RV life a whole lot less stressful, and honestly, that’s worth every penny.

What Other RVers Are Saying

It’s not just us who’ve had a good experience with the Camco Rhino Drain Lock; the wider RV community seems to agree. Across Walmart, Influenster, and RV forums, this adapter has earned strong praise.

Many RVers describe it as a “set it and forget it” solution. Once locked in, it doesn’t slip or shift, which means no more worrying about messy accidents. Several reviewers even called it a must-have for the RV community.

Ease of use is another recurring theme. People love that it’s faster and cleaner than older elbow adapters. One RVer mentioned they didn’t realize how much extra work their old setup was until they tried this one; now they use it on every trip. 

Others pointed out that the apparent elbow allows them to see the drain flow, which gives them peace of mind that everything is working as it should.

The adapter’s availability and price have been hot topics, too. Many people said it was hard to find in stock, and sometimes sold for much higher prices when it first hit the market. While most agree it’s worth the cost, some still feel it’s on the pricey side for a sewer fitting.

Of course, not every review is glowing. A few RVers reported that it didn’t fit certain smaller or non-standard inlets, and one person had the handle break after just a few uses. But those experiences are definitely the exception; the vast majority of reviews are 5-star ratings.

In short, the feedback matches our experience: the Rhino Drain Lock makes RV sewer hookups faster, more secure, and less stressful.

Pros & Cons

Like any RV accessory, the Camco Rhino Drain Lock isn’t perfect, but for us, the positives far outweigh the negatives. Here’s our take after using it:

Pros:

• Quick and secure fit – locks in tightly without wrestling with threads.
  
• Flexible sizing – the 3-in-1 adapter works with a variety of campground sewer inlets.
  
• Odor-tight seal – keeps unpleasant smells contained.
  
• Easy on, easy off – the handle makes setup and breakdown faster and cleaner.
  
• Peace of mind – feels sturdier and more reliable than traditional screw-on elbows.
  

Cons:

• Price is higher than standard elbows or adapters.
  
• Hard to find in stock at times (often sells out quickly).
  
• Fit issues – a few RVers reported it didn’t fit smaller or unusual sewer connections.
  
• Durability concern – rare reports of the handle breaking after a few uses.
  

For us, the convenience and reliability easily outweigh the minor drawbacks. Still, it’s worth knowing that it may not be the perfect fit for every single campground connection.

Who is it Best For?

We think the Camco Rhino Drain Lock is a solid upgrade for just about any RVer, but it especially makes sense if:

• You’re a full-timer – When you’re setting up and breaking down often, saving time and avoiding messes adds up fast.
  
• You travel frequently – If you bounce between campgrounds with different sewer hookups, the flexible 3-in-1 design is a big help.
  
• You value convenience – The easy handle and quick locking system eliminate much of the frustration associated with screw-on elbows.
  
• You’ve had issues with loose or leaky connections – This adapter really shines where other elbows tend to slip or need to be weighed down.
  

If you only camp a couple of weekends a year, you may not need it as much as someone who’s out constantly, but even then, the ease of use is worth it. Honestly, we’d recommend it to any RVer who wants one less thing to stress about during setup.

Final Verdict

After using the Camco Rhino Drain Lock on multiple trips, we can confidently say it’s one of those upgrades that makes RV life a little easier and a lot less stressful. 

Hookups are faster, the connection feels more secure, and we don’t have to worry about odors or leaks. Compared to the screw-on elbows we used before, this is a night-and-day difference.

Is it more expensive than a standard adapter? Yes. Is it sometimes tough to find in stock? Also yes. But for us, the convenience and peace of mind are absolutely worth it. 

RVing already comes with enough challenges; having one less thing to worry about during setup and breakdown is a win in our book.

If you’re tired of fighting with crooked sewer threads, dealing with wobbly connections, or just want a more reliable way to hook up at the dump station, the Rhino Drain Lock is worth grabbing (if you can find one).
