360 Siphon Roof Vent- Black

The 360 Siphon is aerodynamically engineered, it has no wind resistance; it channels wind into its vortex where it creates a low pressure area at the exhaust port. The lid is a complex series of shapes that has taken 3 years of design and field testing. The siphon cannot fail, it’s the world’s only non-mechanical air check valve that eliminates stack down drafts and creates a low pressure area in every possible wind direction.

Product Dimensions-

The diameter of the top- 4.5 in.

Diameter of the bottom with beauty ring installed- 3.5 in.

Height- 3 in.

You’ll need 2.25 in. from the center of the pipe opening to any obstacle that might be in the way.  If your vent pipes are close together, you will need 5 1/8 in. from the centerline of each pipe.

Fits 1.5 inch ID pipe which is standard on most RV’s.  If you own a Tiffin RV or a newer Winnebago RV please call before ordering.  Some vent pipes have a 1.25 or 1.588 ID and those will not work with this 360 Siphon model. However we have a solution, so just give us a call.

How to Use: Install the unit and no longer be hassled with black or gray tank fumes. It’s that simple!

Solve the RV Odor Problem, Don’t Just Keep Treating It

A motto that I’ve lived by my whole life has been “Do it right the first time, so you never have to do it over again”. Doing anything over again is a waste of Time, Energy and Money.

I used this same logic back in 2008 when the holding tank odors in my first RV were so strong they were making me sick. I researched the problem on the Internet and first learned about the sewer gas known as Hydrogen Sulfide. Then I researched the different solutions and realized that deodorizers were not going to solve my problem. I didn’t want to make the sewer gas smell better, I needed to exhaust it out of the holding tank so that I wouldn’t be breathing it inside my RV.

When I reviewed all the vent cap, fume extractors, I realized that they all had moving parts that would eventually fail and need replacement. I continued looking until I found the perfect solution, the 360 Siphon. Yes it cost more than the others, but the advantages are more than worth it. It’s made of Polycarbonate Plastic with UV inhibitors to make it last for years, it has no moving parts that can fail, it has a very low profile to avoid damage, it eliminates the need for holding tank chemicals, and it has 3 patents to ensure it performs as claimed.

After replacing my original stack pipe vent caps with the 360 Siphon I never again had odors, I never again used chemicals, and they never needed replacement. It’s a great example of “Do it right the first time, and never do it over again”.

Sadly, not everyone wants to solve this problem, they make more money just treating the problem at your expense. Recently I spoke with a Parts & Service Manager at a large RV Dealership. I was telling him about how the 360 Siphon permanently solves the RV holding tank odor problem, and how it could save his customers a lot of inconvenience and money.

He looked around to be sure no one could hear him and he said, “Not only do we sell and install holding tank spray systems, we get a lot of repeat business steam cleaning the inside of holding tanks, and selling lots of chemicals. Why would we give up all that repeat revenue for a one-time, permanent solution. Do the math”.

Now folks, it’s your turn to “do the math”. You can permanently solve your RV odor problems with a one-time purchase of the 360 Siphon, or you can continue to be Repeat Revenue for your local RV Parts and Service Dealer. It’s your choice.

Since installing the siphon vent on my 2005 Holiday Rambler motorhome it has eliminated all of the sewer odors from inside the motorhome. This product is amazing. I am very pleased with it’s ease of installation and performance.

I mounted 4 360 Siphons on our Dutch Star motor home and traveled 9200 miles this summer. WOW. What a difference they made. I started the trip using chemicals and stopped using them after 5000 miles. No one in the coach noticed the difference. They work.

The RV 360 Siphons are awesome! I have a seasonal site and every time I dumped my black tank I had a strong odor in the trailer. After installing them I haven’t had any odor inside the trailer. I’ve dumped the tank 6 times after installation and all with the same results. They work great!

Thank You,

BRAVO, BRAVO, BRAVO. The RV in the “RV-360” stands for real value! Finally an end to those funky ODORS. Thanks for a great product.

We are pretty new to RVing and the unpleasant odor condition was a real surprise the first time we experienced it. It would come and go unrepentantly while parked, and was a constant annoyance out on the road. Opening the window to vent the coach made it even worse.

I read about the RV 360 in the good Sam Magazine and I could immediately relate to the problem. In fact every time we went anywhere in our new coach, I was trying to invent solutions in my head. Your product was new and a little pricey, but I had no choice but to try one.

We are very pleased. We drove home from camping in high winds Sunday, perfect conditions for the embarrassing fume situation, and there was nothing. In fact it was windy the whole time we traveled and camped and we never had the slightest whiff. To me, this like the ceiling vent covers, hoses, electrical adapters, furnace exhaust screen etc., which few coaches come with, and must be purchased and installed at the dealer. We thought it almost comical that a new diesel motor home would be missing so many essential components which need to be purchased separately. I now consider your product one of those essentials.

Ease of installation, does its job well, simple/reliable construction, well designed to be functional yet attractive.

I wish this product had been available years ago.

Well worth the suggested price.

I purchased an RV360 in Yuma, Arizona. That was the best money I have ever spent. We had absolutely no odors in the coach while traveling. That was a first . . . Also, we noticed right off that there was no odors in the coach when we dumped the tanks. . . This is a great product and I am telling everyone about it.

You can tell them that Ed Sawyer is a Happy Camper with two RV360s installed on his motor home, one each on the black water and gray water tanks. We no longer have any odor at all in our RV and we did before installing the RV360s. I also feel that there will be no problems with collapsed tanks when getting my tanks pumped with a vacuum truck. I also notice that when I drain the tank, it drains right away like I should and not glug glug like it did. The RV360 allows more air in the tank than the old vent cap.

Smell disappeared within 15 minutes. This is an excellent product.

Lloyd Baker

All the smells disappeared instantly.

Eric Blundell

I wish had it in the summer.

Ron and Kay Neale

Why did it take so long to be invented?

Cleans up the smell in a very short time.

Immediate improvement.

RV VENT CAP

I’m 60 years old and living a life-long dream of living full time in an RV. Even though I really enjoy this lifestyle, I realized it was causing me a serious health problem.

On windy days, or when I towed the trailer, air was being forced down my stack pipes, increasing the pressure in my holding tanks and causing sewer gas, known as Hydrogen Sulfide, to enter my RV. This chemical odor is always unpleasant, but in higher concentrations can not only make you sick, but can actually kill you.

I experienced extreme fatigue, dizziness, headaches, disorientation, nausea, sweating, rapid heartbeat and shortness of breath. I literally felt like I was dying.

After this happened several times, I searched the Internet to learn all I could about this problem. I was surprised to learn that both the Black and Grey water holding tanks create sewer gas that must be properly vented.

I then researched all the Stack Pipe Vent Caps on the market. I read all the websites and even went to the RV stores and inspected all the available caps. Nearly all of them used moving parts that would accumulate dust and dirt and, through friction and wear, would eventually stop working or break.

The vent cap design from 360 PRODUCTS made the most sense to me, and with no moving parts I knew they would never need service or replacement. From the moment I installed them I’ve never had another problem with odor. Great product, I couldn’t be more satisfied. They’re a real life safer.

NOTE, the sewer gas coming out of the stack pipe is heavier than air and, depending on wind direction, can re-enter the RV through an open roof vent. If this happens, just close the roof vent and use the windows for ventilation.

Let us know what you think about Drain Master

If you notice a smell coming in the vent fan, simply close the fan.
