Sanitation Equipment Visa Potty Model

Sanitation Equipment Visa Potty

  • Wide holding tank vent
  • 2-section system
  • Very portable
  • Easy to set up

First on the list is this low priced toilet that leaves everything to the imagination with its design but does a great job in making up for it with features. Available in an 18 and 24 liter model, although this won’t win any beauty contests it will handle anything you can throw at it. The piston pump is replaceable and the bowl itself is cleaned thoroughly with the two directional rinse. Streaks and other waste remnants aren’t left behind, and it is comparable to a home residential model in terms of strength.

To prevent any type of splashing or discomfort the bowl is extra deep, and when not in use the lid snaps close so that vibrations are not an issue when moving. Indicators that are in clear view let you know how much waste is in the toilet as well as how much fresh water is still available. It is an intuitive system that goes the extra mile of being easy rather than complicated. When the spout storage compartment needs to be cleaned, it can be detached and moved around at will. No more worries about all in one systems that are a pain to clean when you’re on the road. Some of the nicer extras associated with the unit is the holding tank for your cleaner so that you don’t have to carry it separate, and the hassle free packaging that it arrives in. There are many on the list but this is a solid starter for those that need a good composting toilet.

Thetford 92360 Porta Potti 550E Curve Portable Toilet

Porta Potti White Thetford Corp

  • The swivel hose
  • Weight: 10 pounds
  • Color: Grey

Up next is this low priced toilet that offers a futuristic polished look. It almost looks like a small space pod if you stare at it long enough, and it has a lot of desirable features like the first model on the list. The seat is loads more comfortable than the first item on the list, probably due to how sleek the material is. Sitting on this will give you a feeling of comfort like you were on your home toilet. The comfort features go a step further and introduce a universal height, increased bowl size and even a toilet paper holder built into the toilet.

These are premium features at a low price, and it’s almost unbelievable how little this costs. Because the flush is battery powered, it has the most powerful flush of any of the portable composting toilets on the list. If power is what you’re looking for in a model, then this is going to be the strongest. It also includes the standard fresh water and waste indicators common for this model, taking away a bulk of the guesswork. Whenever you need to empty the tank, there won’t be any accidents thanks to the improved handle that they included with this model. And with an optional hold down kit, the Potti 550E will probably be the easiest to handle when it gets full. This is the best toilet on the list, and also one of the best looking. If you make this purchase then it will be money well spent.

  • Exclusive, rotating pour-out spout
  • More-ergonomic carrying handle
  • Standard lid latch

Sticking with the low price is the infamous Porta Potti 550p that has the straightforward design of a composting toilet but a lot of extra features. Besides the indicator line that lets you know when to empty it, there is the rotating pour-out spout that simplifies the whole process. If you’re tired of disassembling a composting toilet then this might be the best option for you since the process is simplified. Odors are kept in check thanks to the tightly sealed valve, one of the many exclusives of this model.

A removable seat and cover keeps the product user friendly through its lifetime, and it’s all manageable thanks to the great amount of high quality materials used to make it. This model thrives on a piston pump flush system that packs a considerable punch when used, so it isn’t starving for power at all. Like the last item, the weight is great and it comes in at only 11.4 pounds with dimensions of 16x16x16. There isn’t a lot of beauty to this products design, but to be fair there is only about one item on the list that goes out of its way to look great. If you want a composting toilet that just does the job right then this model is all you will need.

What is a composting toilet?

Best Composting Toilet

While composting toilets have been around for quite some time, they may be a foreign concept to some people who haven’t heard of them, or ever used one, before. A self-composting toilet is not just an outhouse or portable toilet—nowadays there are options for home use—but actually just a great Eco-friendly option as well as a more budget friendly choice, especially for those of looking for a composting toilet for a tiny house.

The compost toilet, no matter which one you get, is designed to naturally decompose human waste and recycle into usable compost—which is great for the environment and can be mixed into your soil for fertilization purposes. A compostable toilet will be able to quickly (depending on the type of toilet you get) compost your waste and recyclable toilet paper, turn your waste into compost that is easy to handle and safe to use, and evaporate all liquid.

The liquid portion can be a little tricky depending on what type of toilet you have—some require you use a medium to turn it into a solid, while others have liquids and solids go to different chambers, so they are easily separated. The waterless toilet system you would use daily in your home will typically be those who can separate the two.

Best Composting Toilet If you have a toilet that separates liquids from solids, you may have the option of “flushing” and/or may have a heated evaporation chamber to help get rid of all traces of liquids. Some of these may also require that you empty out the liquid chamber separate—it just depends on what model you get, so just keep this in mind as you narrow down your choices.

Remember, that no matter what type of composting toilet you get, they all have the same result. Some may get the process done much faster than others and some are more efficient for larger families—but in the end they all take human waste and convert into eco-friendly compost that can “give back” to the environment. Make sure to keep yourself up to date on local and state laws regarding compost disposal, to ensure that you are doing so both safely and properly.

Composting Toilets Types

If you have never used a compost toilet then you may have some questions. While how they work is a relatively similar process across the board, how to use a no water toilet can vary greatly depending on what type you end up getting. Below we will discuss some of the different types of composting toilets and how to use them.

  • Self-Contained

The self-contained composting toilet is a great option for residential use and can be used in the home. The can be electrical or non-electrical and offer lots of additional features most users will love!

If you go with an electric compost toilet, you will have a toilet that comes with a fan as well as a heating element. The fan will help dissipate odors and keep the area free of unwanted smells while the heating unit will help evaporate the liquids. You only have to plug it in when in use and the amount of power they use will vary between 80 and 150 watts, depending on the brand and model you decide to get.

Regardless of whether you get an electrical composter or a non-electrical unit, you will want to make sure that you get a toilet with the appropriate capacity. While electrical toilets may have higher composting capacity, if you don’t need something that has more then don’t pay for the additional capacity.

The best part about the self-contained toilet is that it can be used in the home without any plumbing—since it does not require water. However, you will need to assemble it correctly and ensure you take your time when putting together, and installing, the toilet’s vent stack. This toilet will also evaporate your liquids, so you don’t have to take the time to dump out the contents.

Overall, this composting toilet looks the most like the typical toilet found in the home and can handle use daily use. They are easy to clean and maintain as well—just make sure your home meets all of the requirements if you decide to go with an electrical model. These are also easy to use and keep clean—just do your business and use the additional features as needed.

  • Central Composting Toilet

If you decide to go with a central composting toilet you will have two different types to choose from—a 1-pint flush system and a water-less system. Regardless of which one you decide to go with, they both will be connected to a compost unit located either in your basement or just outside your home.

The 1-pint flush is less Eco-friendly, and many users may not define it as a “real” composting toilet, because it does require water and plumbing. Like the name suggests, it uses about one pint per flush—which is minimal compared to the traditional toilet (which is typically 1.6 gallons per flush instead of just a pint). This toilet’s composting unit will be installed no farther than 20 feet away from a toilet and will require a plumbing pipe that leads from the toilet to the compost. As you can see, this is still an Eco-friendly toilet that uses minimal water and is a great option for residential use. As far as how to use this one, it is pretty much like your typical toilet for the most part, so there really isn’t anything different outside of the fact that it uses much less water and transports waste to a composting unit instead to the sewer.

The water-less central system composting toilet, on the other hand, uses absolutely no water. However, it does also require a plumbing pipe that leads directly to the composting unit and uses an air flow unit to transfer the waste from the toilet to the compost unit. These are a great water saving option for those of you who live in dry areas, want to save money, or just want a more cost-effective toilet in your vacation home or cabin. This toilet is really easy to use and similar to your everyday toilet. While it doesn’t flush like a traditional toilet, it is similar to most residential toilets so, if you decide to use one of these in your home, it shouldn’t take to long to adapt.

  • Split-Systems

The split system composting toilet has become really popular over the years. Not only does it simplify your life and make using a composting toilet much easier, but it also is much more affordable than some of the other high-tech residential type composting toilets

This type of composting toilet, like its name suggests, is split into two different areas—the pedestal and the tank. The pedestal is the toilet area where you sit and the tank is located underneath the pedestal and houses the waste. These are great for home use and typically separate the liquid from the waste, although there are some that still employ the “bucket” type system (which we will discuss later on). Either way, these are more similar to a residential toilet as well and are easy to use. Just keep track of the tank because you will need to dump it in your compost bin as it fills up—an you don’t want to wait until it is too full.

A composting RV toiletis designed for RV use, but some are actually portable enough to also use on camping trips or road trips (although the latter would fall under multi-functional portable toilets. RV toilets can be similar to traditional toilets or they can be bucket toilets—but most often they fall somewhere in between and are most like the split system composting toilet.

Typically, an RV has the black tank that holds your waste and that you have to empty out in specified locations. However, if use a composting toilet in your RV you will eliminate the need for use of this tank, will no longer need any chemicals, and won’t have to flush anymore!

These toilets will typically have the seating area and a tank below. Some may have a separate container for liquids and solids, while others may employ the bucket type system. Regardless of which one you use, these are easy to keep clean—just keep some water and vinegar solution nearby and spray it when necessary, or every time it is used if you prefer. The best part about these is that the you can save the compost material to take home or easily dispose of it anywhere your state and local areas allow. So, no more emptying out the black tank or dealing with any plumbing issues with this one!

Portable composting toilets are really easy to setup and use—in fact, they are actually the easiest to use since they are so simplistic and minimalistic. Many people, and actual users, often refer to them as “bucket toilets” but nowadays they are more than just that.

  • “Bucket” composting toilet

The bucket toilet system can be, as the name suggests, a simple bucket—or it can be a bucket placed under a pedestal and built in area. So, you can still have a toilet bowl to sit on as well as keep the bucket out of sight.

While the bucket system is pretty easy to use, it does take some time to get used to it if you have never (or rarely) used it before.

First and foremost, the bucket toilet will require special composting bags. While there are some pretty generic options when it comes to these, but if you purchase a whole system you may need to stick to the bags made for that specific toilet. And, of course, like all compost toilets, you will need to use a composting medium to set up your toilet and cover up your waste as you go.
