Product Spotlight

By Chuck Woodbury
You’ve heard of the Venturi effect, and you likely know there are people who make their life’s work studying how wind and air currents work. Some of these people specialize in sewer vent systems. Aren’t you glad they do, so the rest of us don’t have to?

Some of these people came up with the 360 Siphon Roof Vent, designed to not only suck out odorous fumes from your sewer system (that’s tech talk for toilet) but also be easy to install, work forever, be affordable, and other good stuff.

I just so happen to own a 360 vent — it’s right up on my roof — and it’s one of the best investments I ever made. If RV manufacturers weren’t so cheap, they’d install these on the roof of every RV they build. And do you know what would happen if they did? Reports from RVers that their RVs smell like an outhouse would nearly disappear. I’ve had my 360 vent for about six years now, and since I installed it, the stink is gone. For me, the problem was worse when I was driving my motorhome on hot summer days, when the contents of ye ol’ sewer tank were perking hot.

Here’s what the manufacturer of the 360 Siphon claims, and from what I know, it’s all true:

By design, the 360 Siphon can only create an updraft (law of physics), and the possibility of odors and gases from the holding tanks entering the RV living space is totally eliminated.

Waste breakdown will occur 3 to 4 times faster and more completely because of the constant, oxygen-rich environment provided by the 360 Siphon. Caustic chemicals such as formaldehyde and perfumed coverups are no longer necessary.

Breathe easier when noxious fumes and gases are no longer allowed to enter the RV living space.

The 360 Siphon can be refitted to any existing RV usually in less than 20 minutes by anyone who can use a screwdriver and a putty knife (to scrape off any old sealants). This permanent, one-time, maintenance-free application replaces the existing factory-installed vent caps.

The 360 Siphon Roof Vent can be purchased for about $30 from Drainmaster or

I installed the 360 venturi vents on top of my refrigerator vent and it’s the first time that my refer hasn’t heated up when traveling down the hiway.

Hi Chuck, I’ve been trying to find out without any success if those metal garden hoses I see advertised on TV and for sale at Camping World are safe to use for an RV and drinking water. I would love to see you publish some information on this type of hose. Thanks for all your dedicated work.

Daniel, you mean those hoses that shrivel up to take practically no storage space? I don’t know if they are good for long term use, but they would do in a pinch if you needed a few extra feet to get to the water faucet. I bought one once to test, and it didn’t last more than a couple months of very part time use. I recommend you use the hoses specifically made for RVs.

Ever since an RV tech turned me on to the amazing product “Tank Tech’s Secret,” outhouse odors are a thing of the past. It’s a bacterial culture that literally turns your tank into a sewage-digestion tank. You no longer need to rinse your tank after dumping, because what’s left is just a little liquid bacterial culture (like yogurt or sourdough starter.) You just add a little more of the magic stuff through the toilet, and there you go. I fought with my black tank for years before discovering Tank Tech’s Secret. It’s expensive compared to “the blue stuff,” but it WORKS and you don’t have to keep buying accessories to try to deal with the failures of various chemicals, especially when it gets hot.

Many have found that just by using a lot of water during flushing and also during rinsing and emptying your black tank helps tremendously with keeping the odors down. In addition if every time you travel, rinse the tank out and put in a few gallons of water plus a cup of laundry detergent and an optional capful of Calgon water softener….will keep the tank from building up any solids in the tank and off the sensors. Using this method I have found that adding ANY black tank additive is a thing of the past and totally unnecessary saving me lots of $$ over time.

I went to the smile amazon website listed on this newsletter but it automatically selects a boys and girls club to support. There are a few other organizations listed but not RV Travel. I did a search for RV Travel but it did not come back with any results. I suspect if anyone uses this link their contribution may be going to something other than what they think. Looks kinda like bait and switch.

Just ignore those prompts unless you would prefer the small commission on a sale goes to any one of those charities. If you click from any link on our site to Amazon we automatically get credit.

I have Prime Products a/c voltage gauge and it will not read the correct voltage when the inverter is on.

Reads correctly on shore and gen power.

Reply to  Harry

Does not read correctly when on the inverter, or, does not read voltages at all?

That’s likely because your inverter is not a pure-sine-wav, and the distorted waveform is fooling the meter. More on this in an article I’m writing on Inverter technology.
