7 Best RV Sewer Vent Cap
Camco Plumbing Vent
My Roadtrek RV didn’t come with a cover on the black water holding tank vents, and it would allow debris and leaves to clog the macerator. The Camco 40033 Plumbing vent was an easy fix for that problem.
[amazon box=”B000EDQQCY” /]
It makes for a cleaner look on the roof and keeps debris away. But that isn’t the greatest benefit; Camco 4033 eliminates all the foul smell that would otherwise make its way to my RV living space. Now, I don’t smell anything.
Another great benefit of the Camco Plumbing vent is that it comes with nice, thick plastic than most OEMs. You can tell it’s not cheaply made and will endure years of abuse. The hard-wearing plastic also has some nice resistance to inclement weather & UV rays and won’t require replacement every few years.
I also found Camco’s versatility appealing. It can fit the 1″ vent pipes, but it also includes a separate cap, which can accommodate up to 2″ pipe vents. It’s a benefit for different RV owners looking to fit their RVs with a vent.
You’ll also find it exciting how easy it is to install this bad boy. The Camco package includes a vent plus hardware and putty tape for installation. It’s simply amazing how quick and straightforward installing this vent is. However, you must ensure you turn the torque setting down on your screw gun so you won’t crack it.
My only concern with the Camco vent is that it doesn’t include a base. It’s not a dealbreaker, but it could be annoying for RVers with a flimsy base.
Pros
- Easy to install
- Thick plastic
- UV-Resistant
Cons
- No base included
Lippert Components Roof Vent Cap
The Lippert Component Roof Vent Cap is an absolute must-have for your RV, especially if you have got an odor problem. The vent cap pulls odor out and draws it much better than the original vents. You won’t even smell the toilets when being flushed-it takes the odor out of the exhaust vent.
[amazon box=”B01CZQ9Y6M” /]
I also can’t get enough of the nifty design meant to keep the larger insects away. It includes a protective mesh that keeps insects that might be looking to colonize your RV. I also found the mesh handy for keeping the leaves and other debris away from my RV.
You shouldn’t have any issue attaching the Lippert Components to any RV vent pipes. It has a universal design, and this is nice because it allows the vent cap to fit any vent pipe without issue or hassle.
Regarding the construction, I’m happy with the polycarbonate plastic design. You shouldn’t be worried that there will be any UV degradation or anything. It’s also hard-wearing and less likely to crack even when subjected to abuse.
Installation is also a breeze, but not a breeze. Easy in the sense that it’s simply a three-step process; remove the old vent, install, and glue. My only concern is the unit is smaller than OEM, so you must mark and pre-drill new holes. It also doesn’t come with screws, which is an added cost.
Otherwise, everything else on the Lippert Components is awesome, and I recommend it.
Pros
- Keeps odor away
- Keep bugs away
- Hardy
Cons
- Installation requires some elbow grease
Camco Cyclone Rotating Vent
I have got a cassette toilet in my RV, and we all know it can be a hit or miss with the smell. However, I put the Camco Vent, and boom! I’ve never had an issue with a smelly trailer again.
[amazon box=”B00SQ1K19A” /]
You see, the Camco Cyclone Plumbing Vent uses wind to draw holding tank odors. The best part about the Camco Cyclone design is that it rotates 360 degrees, which is nice because it can always adjust and follow the wind direction for maximum efficiency.
The Camco Cyclone Sewer Vent also uses the same thick plastic you expect from Camco. It’s not affected by inclement weather and is less likely to get damaged or broken when abused. In short, it’ll last for several seasons without needing a replacement.
Furthermore, I’m pleased with the unique resin covering. It’s handy for protecting the sewer vent against any UV damage. The material is handy and will save your vent from discoloration effects, becoming brittle and breaking apart from exposure to UV rays.
I also love how easy installing the Camco vent is. I mean, it promotes easy installation by eliminating the need for drills or screws. Instead, it only requires you to secure it with the right sealant, and you’re good to go.
Overall, the Camco Cyclone Sewer Vent is an awesome product worth your money.
Pros
- Hassle-free installation
- Thick and hard-wearing plastic
- UV-resistant
Cons
- It’s necessary to use the right sealant
Ventline Sewer Vent
The Ventline 62334 comes as a whole, two-system kit consisting of a base and the actual vent cap. I like the idea of a base for the vent cap, as it’s super handy, especially for folks with RVs with flimsy bases. The Ventline base provides the main support and keeps the entire system sturdy.
[amazon box=”B000778LBQ” /]
Another great benefit of this two-system kit is you can independently separate the base and cap. So, whether you just need a cap or base for your system, the Ventline will work!
But the greatest benefit of the Ventlne 62334 is how effectively they remove odor and smells from the black water holding tank. It leaves your RV space smelling fresh and free from nasty odors.
I also like how well the cap is made. It’s unlike the fragile RV sewer vent caps that get brittle after a few years. Bumping up against the Ventline while on the roof doesn’t damage them. Exposure to V rays and inclement weather also hardly wears them out and lasts for a long time.
The plastic material on the Ventline appears to be better quality than most options, and the durability is one less thing to care about.
Installing the Ventline is also easy, and I love that the cap’s base is already pre-drilled with holes for easy installation. You only need to be concerned about securing the base in the RV’s plumbing vent system and attaching the vent cap.
Pros
- 2-in-1 (vent cap and base)
- Value purchase
- Easy to use
Cons
- No screw
Ultra-Fab Mini Solar Vent
The Ultra-Fab vent is uniquely designed to promote comfort and improve air ventilation in your RV living space. It’s powered by solar power, which provides the energy to keep your holding black tank free from odor. It also maintains your toilet dry yet well-ventilated.
[amazon box=”B004UQV3II” /]
And the best part is since the vent is powered by solar, it eliminates all odors efficiently and noiselessly. Talk of convenience!
Along with the airy performance, several attributes of this vent make it a go-to solution for many RVers. For example, it comes with a nifty, aerodynamic design. It fits seamlessly in any RV design, eliminates drag, and improves overall RV performance.
I’m also pleased with the thick plastic construction. It’s hard-wearing, as you could wish for in the best plumbing vent, which is nice if you need a vent that lasts longer. Furthermore, the vent is covered with a nice finish, which helps prevent degradation from UV exposure.
Installing the Ultra-Fab mini solar vent is fast and easy. It installs easily on your roof, and no wiring kits are required. And once it’s set at the top of the RV, it starts exhausting the fumes and moisture inside.
Pros
- Uses solar
- No whining sounds
- Easy and quick to install
Cons
- Durability issues
Custom Plastics Vent Cap
Our final product, the Custom Plastics 43 RV Plumbing Vent Cap, is a budget purchase. It’s an inexpensive option and perfect for RVers on a budget.
[amazon box=”B004A2YUIC” /]
However, the budget tag doesn’t make it flimsy or mean it lacks some features; far from that.
It’s well-built and comes with a thick plastic design, which is nice if you’re looking for a vent cap that will last for a long time. Hardy plastic is also key for withstanding abuse from inclement weather, especially UV rays. It doesn’t get brittle or even break even after extended exposure to the sun.
But for me, the greatest benefit is how well these vent caps stop bad odors from coming inside your RV. The ventilation properties of this vent are awesome, and once you install it at the top of your RV, you can say goodbye to all-black tank odors.
The ease of installing this Camco vent isn’t something you should sneeze about, either. I love how easy and quick it is to set this bad boy on your RV roof. Many RVers don’t need to go through the manual to set up everything. It takes less than a few minutes to get the job finished.
Pros
- Inexpensive
- Easy to install
- Functional
Cons
- Not universal fit
A Guide to Choosing the Right Recreational Vehicle Sewer Vent Cap
I’ve outlined some of the best sewer vent caps in the market, but knowing how to choose the right option for your needs is important.
In the section below, I’ll outline the factors you must use as the criteria for selecting a vent cap for your needs.
What’s an RV Sewer Vent Cap?
RV sewer vent caps are important components for any recreational waste management system.
Primarily, vent caps funnel the smell up the vent and reduce the amount of holding tank odor that goes into the living area. They also help prevent insects and other unwanted elements from entering the RV.
Different Types of RV Vent Caps
Two of the common recreational vehicle vent caps are:
- Siphon sewer vent cap
- Cyclone vent cap
The siphon vent cap is an amazing design that pulls out all the gases in your black tank. It utilizes a fan, spinning rapidly at 360 degrees. The fan generates pressure, which sucks out all the air from the tank and releases it from your RV.
On the other hand, the cyclone design uses natural air pressure to keep the bad odors away from your vehicle. I’m a big fan of the cyclone design because it doesn’t require installation; you only need a sealant.
Choosing an RV Vent Cap
Efficiency- Uses the Power of Nature
A perfect RV sewer vent cap should leverage the power of nature to eliminate unwanted odor. Most sewer vent caps usually use the airflow from the wind to get rid of the awful smells. Others use solar energy to flush out the odors and keep your blank tank free of moisture.
UV-resistant
A sewer vent cap should be UV-resistant and should be able to withstand long-term exposure to sunlight. Remember, the caps are constantly exposed to the sun, which may lead to cracking and premature wear.
And so a great way to extend the longevity of a vent cap is to pick one with UV-resistant properties.
Durability
In addition to UV resistance, the perfect RV sewer vent cap should also be durable. It shouldn’t be flimsy, and it shouldn’t break down easily.
After all, it’s an expensive purchase, and you don’t need to replace it often. Consider the type of material used on the sewer vent cap. Most vents are made from plastic, but I suggest you consider those with hard-wearing quality plastic.
The perfect RV sewer vent cap should last for years and should be able to take a lot of abuse without breaking down.
Easy Installation
The last thing you need is to struggle when attaching your RV sewer vent. Your choice of products should be easy to attach and should come without the risk or hassle of breaking anything.
The good thing is that most vent caps usually come with some sort of user manual to help with installation. I recommend those with a tension spring for the easiest-to-use RV sewer vent caps.
Price
Finally, it’s always a good idea to consider the price. My rule is to go with whatever you feel provides value for your needs.
The most expensive sewer vent caps aren’t necessarily the best options. However, going too cheap on your sewer vent cap may lead to quality issues.
But generally, sewer vents caps don’t cost much. You should, however, have a budget and consider every feature and quality you want for a sewer vent cap.
Wrap Up
That’s a wrap and everything you need to know about the best RV sewer vent cap. Our guide will help you select the ideal sewer vent cap for your RVing needs. I’ve also outlined different options, so you’ve a variety to choose from.
The key thing to keep in mind when selecting the right RV sewer vent is that it should provide proper ventilation to keep odors away. It should also be durable, easy to use, and practical.
