If you have ever experienced that unmistakable smell inside your RV, you absolutely know it is not supposed to be there EVER! Why it came into the living space of your coach is in all probability for one or two reasons. If you have been travelling down the road when you smell it or enter the coach when you stop, the possible problem is water has escaped out of one of the P-traps in your sink or shower, breaking the “water seal” created in the RV P-trap and allowing the sewer gases back into the living space of the RV.

The other possibility is that the holding tank roof vent allowed the outside air to enter the vent stack, creating a positive air pressure in the holding tank and the air is seeping into the living space through a poor seal somewhere.

With our most recent partnership with 360 Products Inc. we are in a position to help eliminate sewer odors in your RV once and for all, guaranteed. As you may already be aware, we sell the HepvO waterless RV P-trap which eliminates the issue of water spilling out of the traditional P-trap, however, if you have positive air pressure in the vent system, the potential for sewer gases to permeate the living space still exists.

We have looked in the past at carrying a roof vent but any of the units that worked required moving parts. The first on the market to address this problem was the 360 Shark Fin that turns in the breeze, causing a negative pressure in the vent stack and holding tanks. It’s popularity with consumers caught the eye of a couple of companies known in the RV Industry for “knocking off” good products and two more appeared on the market. The original inventor of the 360 Shark Fin knew this device had limitations, and his goal was to make a product with no moving parts that was very low profile and would never allow a negative pressure in the vent stack, under any wind condition. Five years in development and hundreds of models tested, the perfect unit emerged and they could not make it fail in any of the test labs it was sent to!

We are proud to be partnered with 360 Products Inc. and with the 360 Siphon added to our waste management product family, we feel all our products are designed to make your RVing experience uneventful when it comes to dealing with human waste issues.
