Wire hose clamps have a lot going for them. For one, they are low profile and don’t tend to gouge chunks of meat out of your fingers and knuckles when working around them. Having done almost everything around my house and on my sailboats for years, I have come to appreciate a good thing. Here is a quick primer on a wire hose clamp that I invented. There are several tools on the market that make nice wire hose clamps. I have owned two and used them. They have their limitations, especially in confined areas where you are likely to find need for them. Anyway . . .
I have been experimenting with several pump types to use in conjunction with the pump tank accessory. The pump tank accessory, to review, is a reservoir that holds the urine until it can be pumped out to a holding tank. The pump tank isn’t necessary in situations where gravity feed will empty the tank, that is situations where the holding tank or drain field is below the toilet all the time. There are a few situations where the holding tank or drain field sits above the toilet or where the drain line must clear a hurdle that is above the toilet. Most sailboats have the holding tank mounted higher than the toilet because they don’t have room in the bilge. Also, Granny in the basement installations and most below-ground prepper bunkers will need to pump the urine uphill. In those cases, the pump tank is a good accessory to have. The pump system can be manual or electric.
I know it sounds self serving for me to tell people that they shouldn’t build their own toilets but hear me out. Live aboard boaters and RV owners are usually very handy. You basically have to be. You’re out in the middle of no-where and something goes wrong and there is nobody you can hire to fix it and no place to go to get parts, at least proprietary parts. When I built the C-Head I kept this in mind and made it so that parts could be easily found at local hardware stores. Having lived aboard two sailboats for a total of nine years, I knew that that would be a valuable consideration for my product by people who would use it. I also knew that because of that, people would try to imitate the design, thinking they were saving money and getting the satisfaction of being creative all in one deal. I mean it’s just a bucket and a jug and a box and a toilet seat, right? But let’s look at that.
The first in a multi-part series of articles on ventilation
Ventilation is one of the most complex aspects of any composting toilet system, but it shouldn’t be. Almost all urine diverting standard sized and compact composting toilets require ventilation. In some, like the Separatt, it is the sole means of removing the smell and moisture produced by processing the solid waste. Urine odor can be fairly well confined to it’s container, but pouring it out is a stinky process indeed, unless you have treated it with a holding tank solution. Treating it is common with mobile applications like boats and RVs because public restrooms are often the place they get emptied and you don’t want to chase everybody out of the bathroom and have them complaining to the management. But I digress . . . This is a series of articles on ventilation. First I will discuss boats, except for houseboats with RV type flush toilets that use a floor flange which I address in the Part 2 which is RV and travel trailers. Part 3 will be fixed applications like homesteads, cabins, tree houses, etc and Part 4 will be prepper bunkers which are a special case and Part 6 is tiny houses, also a special case.
One of the great advantages of the C-Head is the ability to easily funnel the urine out of the toilet into an outside receptacle such as a black water holding tank like those found in boats and RVs, or an agriculture type storage tank for permaculture use or into a drain field. You can do this using what we call the “bottom exit kit.” In addition to home and cabin installation, this can be done with most RVs, travel trailers and houseboats that have an original, factory installed toilet that flushes into a holding tank through a standard toilet flange that is mounted on the floor. Diverting urine to the holding tank in its concentrated state takes much longer to fill the the tank up and thus significantly extends the time between dumping the tank . In addition, it makes the disposal of urine much easier for both boondockers and for RV and travel trailer owners who prefer to use dump stations. More on that in a minute.

So now we have to get a little personal. Having spent a lifetime directly involved with hands-on medicine as an Army Special Forces medic and as a municipal and then county firefighter/paramedic, and having been married three times, I thought I knew pretty much everything about female anatomy . . . well almost everything. But once I got into the toilet business, I found out some things that I didn’t know and that were surprising. Number one, as many women order my toilets as do men. It may be because, between the two of them, she is the one with the bank account. More common than you would believe. And number two, women’s anatomies are significantly different with respect to what we call “directional stability” in the boat design business. And number three, when women go to the bathroom (#2), they usually don’t go #1, then #2, nor do they go #2, then #1. They usually go #3. That proved to be a challenge that I hadn’t expected to have to overcome.
The C-Head toilet is available with two options regarding the processing of solid waste. The churning version and the churnless version. One has a churning mechanism to move the medium around (medium = sawdust, wood shavings, peat moss, coco coir, etc.). The churnless does not. Each has its advantages and disadvantages over the other. The difference in cost is $35 with the churnless version being cheaper, so if you are uncertain which version would work best for you, we suggest you get the churning version and modify it into a churnless version for testing. You may want to convert the systems back and forth depending on who is using the toilet. For example, if you are having guests who are not used to using a C-Head, you may want to use the churnless version during their stay for a couple of reasons. So let’s look at the differences.
