We don't get any smells inside our 5vr.....cause all the vapor barriers and seals work.

We don't get any odors when dumping cause the o-rings in our sewer hose/fittings work and the sewer clean out adapter screws into sewer pipe.

We don't use ANY chemicals other than water.

We've full-timed for 16 years and have never had smells. All we use is water in our black and grey tanks - no additives. There's no need to do so and you're just wasting money.

For the grey tank, we don't throw any garbage, grease or coffee grounds down the drain. We wipe everything off with a dirty napkin or paper towel before doing the dishes.

For the black tank, we just use plenty of water.
