Natures Head bathroom smell
We have had our Natures Head toilet for about 3 years and occasionally we have had a mild but unacceptable smell in the bathroom. Here is what the situation is today:
- Down in Texas with the temperature from 56 - 64 degrees in the Airstream
- A few days it gets to 72 degrees with no wind
- Quite windy most days
- New batch of compost with about 3 weeks of use by 2 people
- The compost looks like it is just the right amount of moisture, maybe slightly dry if anything
- The smell comes and goes - sometimes within a couple of hours, sometimes a whole day with zero smell
I have replaced the rubber grommet around the base and removable top section. It appears to be sealing well. I checked that the fan is blowing out and that there is no leaks in the short flexible tube from the fan to the "T" I put into the plumbing stack vent pipe that exhausts out the top of the Airstream (25' FC 2017). When I strike a match and watch the smoke it is not being pulled into the intake vent on the opposite side from the fan. Neither is it being pulled into any other place around the toilet.
I have tried to open the bathroom ceiling vent, windows ,etc. in case this is the outside wind (10 to 18 MPH) overcoming the fan and pressurizing the compost bucket and forcing the slight smell back into the room.
Thinking maybe venting it out the side of the Airstream may help?
Any ideas would be most appreciated!

Just got off the phone with Michael at Nature's Head. Good discussion and we are going to run a test from now until Monday where I have shut off the fan, disconnected the hose from the fan and plugged off both the hose and the fan output. We will see if the smell goes away. Michael believes that there is a good chance that the rain cap on the roof plumbing vent pipe is allowing excessive wind pressure to blow air back into the toilet and subsequently into the bathroom.

Let us know if this works. I think most of us with black tanks have had sewer smells on windy days, or when the bathroom exhaust fan is running, when the toilet flush valve is opened.
Some Nature Head users talk about emptying the toilet every 2nd day or so. Would more frequent clean outs help?

One empties the pee bucket every 2 days (for us). The compost bucket can take about 40 uses before it is full. The slight smell we have is that of the compost.
On the Natures Head website they have for sale a vent cover that is an anti-wind device. Ill look at the one mentioned above to see how it would handle the wind - it looks much more streamlined than Natures Heads version.

Nature's Head owner for four years... We have found that if we start getting any kind of smell it's time to check the screen on the fan section. In normal use there is enough dust, etc. that while the fan is still working it isn't drawing enough air through to keep odors from building up. Our rule of thumb is that whenever we empty the Nature's Head and put in new coconut coir we clean the filter. You can get to it from the inside, and with an old (!) toothbrush can clear off the dust and stuff that clogs it up.

Go point on the screen filter. I did check it and it was clean. Ive had the hose disconnected for 24 hours and zero smell in the bathroom, except a very slight smell when I open the toilet seat. Which is to be expected as the fan is not running. I just put a 4 PVC pipe end cap over the Airstreams vent fitting on the roof. It looks like it will block the wind and still allow the vent to work. Ill report after a few days and hopefully some wind.

Just a thought...Have you considered putting back the original Thetford porcelain toilet? (now don't go skewering me; I'm just making a logical comment!)

We like going to state and federal parks with zero or only electrical hookups. Easy to get reservations and much more roomy and scenic campsites. With the composting toilet we can go one or even 2 weeks before needing to empty the tanks. Even then we can use my portable pump and tote to dump the grey water. Gives us more hiking, kayaking, photography time as we usually stay in one place for the whole 1 or 2 week vacation time.
90 percent of the time there is zero smell. I am pretty confident we will get this resolved to my wifes satisfaction. Now I am waiting for the winds to pick up to test out the new vent cap.

I can understand the desire to stay off grid for longer periods of time that a 'composting' toilet offers, but they are expensive, can smell (as in your situation) and the liquid and solids still need to be gotten rid of. They may be a good solution in a country cabin where you have a place to actually compost the waste rather than just throwing it in the garbage. Great marketing by Natures Head and other composting toilet manufacturers to convince people that this is the only way to avoid filling up a black tank quickly. IMO, I think they would also decrease the resale desirability of a modified trailer.
There are other simpler solutions for keeping your black tank empty for long periods of time. We have used ' Wag Bags' in the past, but they are fairly expensive. Less expensive, but just as effective are commode liners. Either of these fit into your regular toilet bowl and are permitted to be disposed of in garbage bins. IMO the bags are less distasteful to use then stirring the solids or having to empty the liquids every day. The bag method of waste disposal is also very useful when travelling and your trailer is winterized or no water is available for your regular porcelain toilet.

I agree that "dry" toilets save water in the black tank and the need to empty it. Most of the state parks I've stayed in have a bath house with toilets reasonably close by. It isn't as handy or comfortable as our Airstreams, but it is an option for me to reduce water in the black tank when on extended stays without hookups.

I don't get this. Not having camped someplace without services for two weeks, but at least one. The biggest problem first becomes lack of fresh water. About 55% might go to the gray tank. Maybe 20% tops to the black tank. The rest, is consumed. The blank tank is the least concern.
Fresh water is by far the biggest limiting factor.

It's a lot easier to haul in fresh water than to haul out waste water.

Natures Head bathroom smell
I suppose that unless you have been exposed to the how-to *waste disposal* (only need a shovel) means in the back-country, a CT is a bewildering idea for many.
Water is the limiting factor. We carry this in our tool arsenal for our full-time AS lifestyle. Or, perhaps we just want to live *unplugged* at this stage of our lives...preppers at heart. [emoji4] In case of the zombie apocalypse we are self-sufficient in our silver conestoga wagon. As long as we can find water and fill our Berkey filter with pond scum wel survive!

60 gallons water= 501lbs...there goes the payload! We always carry 2 "empty" 5 gal water containers with us; we purchased 4 of them and use to carry them as they "lock" onto each other, but now days we only take 2 along. We have found 10-20 gallons refill after 5-7 days works fine for our needs. We also carry 3 gal container of fresh inside the AS for coffee and drinking water. When we boondock and run out of fresh water, it's not a hassle to fill the containers up and replenish the fresh tank. Most state parks and BLM campgrounds have fresh water and a bathroom or pit toilets, which we use as needed. We can go 8-10 days before we need to empty the black tank if no toilets around. We do run the gray out sometimes while boondocking in the desert or the outback via a gray water hose connected to the sewer cap...works fine for us.

@gyspydad - we have this to fetch water and use gravity to completely fill the fresh water tank when empty. Fetch water - fill tank. No lifting a 50+ pound jerry can to fill the tank. Bladder folds up to a small size. It is much smaller than a jerry can, and weighs next to nothing when empty. We do not haul water in the AQUATANK2 when towing the AS. Our truck can easily handle the 500lb+ payload.
We learned having a water bladder is a great idea because of traveling with our horses. Fetching water becomes an absolute necessity when camping with horses. Its easy to water horses using a water bladder, so why not the humans? The AQUATANK2 is rated for drinking water.

Interesting idea. My 5 gal water containers weigh around 40lbs each when full and at least today, I can manage them fine. I usually will fill them only when I need to so not an issue for me yet. I don't have to deal with horses, but makes sense using the larger container. Hadn't seen these before...I see they have several sizes; thanks.

Had to wait until the wind picked up agin to test out the 4 end cap vent solution. I feel that it worked well as the 25 MPH winds did not blow back into the bathroom with it installed. $3.00 solution!
Without the wind and a day later there was a slight compost smell in the bathroom so the testing continues. Planning to double up on the fan to put more of an airflow out of the toilet.
