Dry closet for the home violates the principles of the saying "One man is not a warrior"

When it comes to plumbing, it is generally accepted that all plumbing fixtures in an apartment or private house are interconnected by sewerage and water supply systems. But a portable dry closet easily breaks this rule, being a completely autonomous object, the only "warrior in the field." This is what I want to tell you about.

Acquaintance

I had the following situation: the country house was already insulated, equipped with electrical wiring and furnished, but there was no sensible septic tank yet, which greatly limited the possibilities of sewerage, and the bathroom itself also needed to be arranged. And I wanted to experience a suburban way of life as soon as possible, so I began to look for a way out of the situation.

I did not want to fully rely on a street closet in the 21st century, and in this regard, I turned my attention to dry closets, or rather, their positive qualities:

Advantages

• No need for a sewer system. That is, you will be able to use such a toilet before you equip the capital one, or even save the family budget altogether by refusing this step, which will amount to quite a significant amount of money. Of course, the second option is not always and everywhere implemented, because you also need to remember about the shower and the washing machine, but it is worth considering;
• Mobility. It is not at all necessary to place the equipment in question in a room specially designated for it, it can be placed in any part of your house or apartment where it is most in demand at the moment;

• Ease of use. This is still the same comfortable toilet seat with a lid and a seat, and in modern models even with a drain. So you will feel no less comfortable than in the case of using a conventional familiar toilet;
• Source of high quality fertilizers. This plus will be appreciated by every gardener;

• Complete absence of any unpleasant odors. Dry closets are designed so that the smells of human life products do not spread from them, which once again testifies in favor of the absence of restrictions regarding the choice of their installation site.

Flaws

Along with such significant advantages, I also noted a couple of disadvantages associated with some operational features of the equipment in question:

• The need to add special fluids to the system which requires some recurring costs. On the one hand, they will not hit your pocket hard, and on the other hand, an ordinary toilet bowl does not require regular expenses at all;
• The need for systematic removal of accumulated waste and adding water to the flush system with your own hands, which takes up some of your free time.

Thus, we can safely say that mini dry closets for the home will perfectly solve the problem with the lack of a capital sewerage system or the need to place a bathroom in a non-standard place, which may be due to the presence of old people, small children or the disabled in the house, but at the same time they will require a little more attention than standard toilets.

After such conclusions, I proceeded to study the structure and principles of operation of the equipment in question:

Device

Designation on the diagram	Element name
1	Removable seat with cover
2	Cover from the drain tank
3	Toilet
4	flush key
5	Built-in swivel type drain
6	Cistern
7	Reservoir for receiving wastewater
8	damper
9	Valve key for air release
10	Tongue that opens and closes the flap
11	Indicator signaling the filling of the wastewater tank
12	Toilet liquid pocket
13	Valve
14	Latch fixing the drain tank
15	pipe cap

How does the described system work? It's very simple: human waste products enter the upper compartment, after which, by pressing a key, a flush is carried out, and its contents are transferred to the lower wastewater accumulation tank. The valve located between the two parts of the structure is responsible for the tightness of the sewage tank.

By the way, it is this principle of the toilet that is best suited for a motorhome, in which the sewer system is not brought out, but is closed.

Choice

How to choose a dry closet? I followed the following criteria:

Main criteria

1. Volume. On the one hand, there is a direct correlation: the more people live in the house, the larger the wastewater tank should be. But here you should not forget also about the need for manual emptying of the tank.
   That is, if it is possible to take out, for example, a heavy container on a compost heap, then you can take overall equipment, but if this is difficult, then you should think about taking a small model and simply emptying it more often;

I also recommend focusing on a sanitary liquid, the activity of which lasts no more than two weeks. That is, no matter how large the wastewater tank is, at least once every half a month you still have to perform its maintenance.

1. Pump type. Pumping equipment determines the ease of pressing the flush key and the efficiency of the process that is started. So, due attention should be paid to it. There are three options here:

• piston system. A hard start is compensated by the possibility of dosing the released liquid and the simplicity of the device, due to which the repair of such equipment can be carried out independently;
• pump system. Pressing the key is much easier, but it is no longer possible to dispense water, and in the event of a breakdown, you will have to call a specialist;
• electrical system. There is also an easy start-up and dosing of the drain, but at the same time it is necessary to change the batteries in time, without which this one will not be able to work at all. Repair work requires the participation of qualified specialists;

1. The presence of an indicator of the occupancy of the container with drains. Without this simple device, you will have to periodically look inside the tank in order to have an idea of ​​​​the amount of free space in it, which will cause some inconvenience;

1. Air release valve allowing pressure to be released. Thanks to this device, the drain will be carried out without splashing, the advantages of such a system operation are obvious.

Examples of Existing Models

My shopping trip introduced me to the following models:

• Model "Thetford Porta Potti Qube 145":

• Model «Thetford Porta Potti Qube 165 Luxe»:

• Model "Thetford Porta Potti Qube 335":

• Model «Thetford Porta Potti Excellence»:

• Model "Mr. Little Ideal":

Parameter	Description
Country of manufacture	Canada
Drain type	Piston with double-acting effect
Waste tank volume	24 l
Clean water tank capacity	15 l
0.25 t
Color	White
Pressure relief valve	Present
Waste tank full indicator	Present
Upper tank full indicator	Present
Width	420 mm
Length	410 mm
Height	370 mm
Weight	5000 g
Approximate period of filling the lower tank	5-9 days
Price	6800 rubles

• Model "Thetford Porta Potti Excellence Electric Granite":

As you can see, the price of a dry closet for the most part depends on the parameters that I described above. And you can choose both a relatively cheap "Spartan" model, and an expensive sample, stuffed with all possible devices.

Operation features

How to use a dry closet for the home can also be found in the instructions attached to it, but still I want to tell you more about the preparation of equipment and its maintenance, since such information is still not superfluous:

Preparation for use

1. The first thing I did after getting the equipment home was to moved the latch connecting two tanks, and divided them;

1. Then I put the waste container on its side, directing its outlet up. Opened the plug and filled with disinfectant liquid so that it completely covers the bottom. This drug eliminates odors, accelerates the decomposition of human waste products and cleans the tank from the inside. It is produced by a variety of companies, although the composition is always approximately the same, so I will not dwell on its analysis in detail;

1. Closed the cork, turned the tank over to its original position and again installed the upper part on it, snapping the latch;
2. Now open the lid and poured water into the drain tank, mixing it with a special flushing solution that improves the quality of flushing. After that, the equipment can be considered ready for operation;

Service

If your model has an indicator, then, as a rule, it signals the need to remove the contents when the filling of the tank begins to exceed three-fourths of its full volume. In this case, you should do a number of such actions:

1. unfasten using a latch, both containers are separated from each other;
2. Waste tank carry away to the place of his devastation;
3. Place the container on its side, unscrew the lid and, slowly tilting it, to empty. At the same time, to avoid splashing, you should hold down the air supply button;

1. The last step is to Rinse tank and then it can be used again.

If your model has an electric pump, then do not forget about the need to periodically change the batteries.

I recommend once a month to spray a special cleaning liquid on the surface of the dry closet, which is a composition of chemically active substances, and then rinse it off. So you will significantly extend the life of the equipment.

Conservation

In my case, after the dry closet had properly served its time until the appearance of a major bathroom, I safely mothballed it until the time when I need such equipment again. To do this, did the following:

1. Completely emptied both tanks: both drain and waste;
2. Pressed the flush button to make sure there was no water in the system;
3. I left all the elements disassembled for some time until they were completely dry;
4. The gaskets connecting the tubes were smeared with ordinary olive oil;
5. Gathered the equipment again and placed it in the pantry.

In this state, the unit can be stored for a very long time, waiting in the wings.

Conclusion

Buying a dry closet will help solve a lot of problems associated with the lack of a full-fledged sewer system or with other force majeure situations. But you also need to choose this equipment correctly according to your needs. Operation, although it looks somewhat more complicated compared to a conventional toilet, is not something overwhelming or requiring any special skills.

An overview of the most common types of dry closets will help you make a choice.

Electric dry closets

If electricity is supplied to the installation site of the device, there are several solutions:

Dry closet with freezing. This is a container with a "freezer": the waste is packed in biodegradable bags and cooled to low temperatures, which guarantees the absence of an unpleasant odor. Such devices are emptied quite often due to the small collection capacity, for example, in a compost pit. Suitable for installation on board an airliner, and for mobile offices, and for caring for patients with disabilities.

Dry closet with burning function. Recyclable waste, right in the storage container, is heated to high temperatures and turns into ashes. And it can already be disposed of as ordinary household waste. The devices are suitable for all possible installation cases, the limitation is only the high price.

Dry closets without electricity connection

Models without the use of electricity are also divided according to the type of disposal:

Peat bio-toilet with dry flush - model with backfilling of waste with peat mixture that absorbs moisture and neutralizes odors. An excellent option for summer cottages or home gardens: the contents of the storage tank of the device, already ready for “ripening”, are emptied into a compost pit and used, after a while, as fertilizer.

Cassette dry closet - waste products are collected in a sealed container - a cassette, where they are neutralized with the help of added septic tanks. When the container is filled, its contents are poured into a sewer or sewer. Such models are suitable for long-distance buses, camping.

But even in these devices, for example, a flush pump, a mixer, and compost heating can work from an electrical network or batteries (accumulators).

What dry closet is better to buy?

It all depends on the scope. For patient care or short trips, the light and miniature Thetford porta potti 365 (the leader in popularity among dry closets) and Dometic 972 are the best option. For summer cottages, peat composting dry closets are most often chosen. If we are talking about long-term residence outside the city, and there is no possibility to install a sewer, then more voluminous models will help. Well, for those who are not used to denying themselves anything, for example, Separett Flame 8000 or Biolan Icelett will be an excellent solution.

Liquids for a dry closet that increase the comfort of using it? Ivan 07/29/2012 20:51

For the lower tank, there are two types of special waste products Aqua Kem Blue and Aqua Kem Green. They destroy odors and recycle wastewater, turning them into a homogeneous mass with a medical and cosmetic smell. When using Aqua Kem Green fluid, waste can be composted. If it is possible to drain waste into the sewer, it is recommended to use the economical disinfectant Aqua Kem Blue.
It is also recommended to add Aqua Rinse fragrance to the water of the upper tank, it not only eliminates unpleasant odors, but also facilitates flushing. It is difficult to wash off solid waste with water alone, and thanks to this agent, they can be washed off in one flush - only 120 ml of liquid, in some cases it is necessary to drain the water up to 3 times.
All Thetford dry closet liquids are concentrated solutions. For example, one 1.5 liter bottle of Aqua Kem Blue or Aqua Kem Green liquid is enough for about 3 months of use for a family of 3 people.

Due to what is the flushing of water, the difference between pumps (pumps)? Vyacheslav 07/29/2012 20:49

Administrator 29.07.2012 20:49

Pump (pump) - provides water supply for flushing under pressure. The pump of the new sample is a mechanical pump in the form of a pump piston. The old-style pump (bellows) is also mechanical, but made in the form of an accordion and is more brittle. With a pump-action system for flushing a dry closet, it is impossible to dose water. There are models with electric drain - Porta Potti 465 (powered by ordinary batteries), Thetford C402C (powered by a 12 V power source). An electric pump, when the shutter button is pressed, dispenses water, saving it, and provides the necessary pressure for draining. Replacement of such a pump (if it fails) is possible in the workshop, but it is extremely reliable.
The simplest flush system is a piston pump. It provides a more powerful water pressure for flushing and has a manual (mechanical) or electric drive. To obtain a sufficient flush pressure (with a mechanical drain), you need to make some efforts, then you get a strong pressure and a dosed portion of water. You can replace such a pump yourself.

The market was flooded with cheap low-quality fakes for expensive, high-quality, long-established dry closets from a Dutch company Thetford . Of course, many unscrupulous entrepreneurs are attracted by easy money, when you can invest 3 kopecks, bring a truckload of burnt Chinese toilets with Thetford inscription, and passing them off as original ones, earn 200% or even 300%. Only, naturally, they don’t care about your health (it’s not yet known what these singed cheap shocks are made of, and what will appear on your skin after sitting on it, and what phenols or other muck you will inhale!), And even more so how long you can use and where you will then repair this Chinese product.

You have a big risk of buying a fake dry closet!

Remember that the Dutch company Thetford recommends a retail price for its dealers, based on the interests of the end consumer, so that dealers do not overcharge! Selling below the retail price of Thetford'a dealers with all their desire can not, because it will simply be unprofitable. But Chinese dry closets with the inscription Thetford can just be sold cheaper and it will be even more profitable!!!

The easiest way to make life in the country more comfortable is to equip a good sewerage system. But it takes a lot of time and money to invest in it. There is an option to arrange a normal latrine in a couple of hours or even in a few minutes - a dry closet for a summer residence. There are three different types of installations. Each of them has its own advantages and disadvantages, but anyone can be operated outside the city (and not only).

Peat dry closet - the principle of operation and device

In the peat dry closet, in the part where the usual one contains water, dry, finely ground peat is poured. This tank has a device for spreading the substance, which is operated by a handle. After using the toilet, turn the handle, the peat will spread over the surface, blocking the waste, which will significantly reduce the smell. Because of this feature of the work, a peat dry closet is also called a powder closet. Another name is composting toilets, as waste can be placed in a compost pit. True, this class includes another type of dry closets - electric, which dries excrement.

The next name is dry dry closets. Again, the name is associated with a method of waste disposal - powdering with dry peat. As a result of processing, the substance is also dry (or almost dry).

Due to the high absorbency of peat, it absorbs part of the liquid component of the waste, and the rest is drained into a special tray below. From there, the liquid is discharged through a special drain hose. He is usually taken out into the street, into a small pit.

The solid part of the waste is processed by bacteria contained in peat, which decompose organic matter. After processing, the container contains a mixture that is almost odorless. It can be safely poured onto a compost heap, that is, peat - an ideal dry closet for a summer residence. But the waste should lie on the heap for at least a year, and preferably a couple of years.

Since complete processing takes time to eliminate the characteristic smell of waste, a pipe must be attached to the peat dry closet (there is an outlet pipe, in some models plastic pipes are included). If the thrust is natural, the pipe is only straight, without bends and bends, at least 2 meters high. If desired (if natural draft is not enough), you can put an exhaust fan. Then the requirements for the pipe are not so strict.

Advantages

If you need a dry closet in the country - this is one of the best options - just a sea of ​​\u200b\u200bpluses:

All in all, a very good choice. Usually both the owners and neighbors are satisfied - there is no smell, problems with processing. But you can't do without cons.

Flaws

The weak point of peat dry closets is the peat spreading device. First, so that the peat spreads evenly, first turn the handle in one direction, then in the other. Secondly, it is not a fact that it will be evenly scattered. Often it is necessary to pour peat from the scapular reserve under the "hole". It is in this place that he gets the worst, and all the waste is concentrated here. It is necessary to sprinkle them, so you also have to manually fall asleep.

Other disadvantages of peat toilets are:

If we talk about the degree of convenience, this is a good choice, but only if it is possible to put it somewhere permanently. You can move the device, but each time you need to install an exhaust ventilation pipe.

Popular models of peat toilets

If we talk about domestic manufacturers, then the most affordable models of peat toilets are produced in St. Petersburg. The company "Tandem" produces peat dry closets Compact. They are available in different versions, with different options and prices.

Liquid (chemical) dry closet - device, pros, cons

This type of dry closet uses special liquids to process waste. The design has two containers into which the concentrate diluted to a certain state is poured. A liquid is poured into the lower part, which processes waste, into the upper part - with a deodorizing effect. Processing fluids are of different types:

The device is operable only in the presence of the specified liquids. The rate of their consumption depends on the intensity of use. On average, refueling is required every 5-7 days.

Structure

The chemical dry closet consists of several parts that are easily separated. The upper part is both the seat and the container into which the fragrance is added. On the back right on the cover of this compartment there is a button to start the pump, on the left there is a hole for filling water.

The processing concentrate diluted with water is poured into the lower tank. At the very bottom there is a box for collecting waste. The capacity of this tank is from 12 to 24 liters. In order to be able to monitor the degree of filling of this tank, there are models with a fill indicator. As it fills up, the color changes from green to red. In those tanks where there is no such indicator, a strip of transparent plastic is often built in. To be able to visually monitor the level of waste.

All parts are interconnected with special locks that securely fix them in place. To make it easier to take out the waste, a handle is attached to the bottom container. There is a pipe for draining waste into a container. It is screwed to the inlet if necessary. In general, it is stored in a specially designated place.

Some models have a built-in pressure valve in the faeces tank. It is needed in order to empty the container was easier. But there is one minus in this - there are times when leaks begin at the attachment point of this valve. Carrying the container by the handle then does not work, it is necessary - in front of you on your hands. Quite inconvenient.

The flush pump can be manual or electric. When using electric, there is no way to regulate the amount of water supplied - it is always the same. Because of this, the tank fills up faster. The device runs on batteries that need to be changed periodically.

Hand pumps are bellows and piston. By pressing with different force on the piston, you can adjust the amount of water supplied.

Preparation for work and operation

The operation of a liquid dry closet is simple, but requires constant attention. It is necessary to control the presence of liquid, the level of filling of the waste tank. It is quite common to take out and dispose of waste. The capacity of 12 liters with a stay of 2-3 people is filled in 2-3 days. If there are more people, you have to endure every other day, And sometimes every day. Not very convenient, although much more convenient than using a bucket.

The procedure for preparing a liquid dry closet for work is as follows:

• Detach the top by pressing the button.
• Pour the appropriate solution into the container.
• Put the containers in place, connect the lock.

Everything, the dry closet is ready for operation. Must be washed off after each use. The portion of the liquid is small, but it is enough to clean the drain. The mechanism is as follows: use the toilet for its intended purpose, open the valve, the waste falls into the container with the processing liquid. Rinse off with scented water, using a brush if necessary. Close the valve. So that there is no smell from the liquid dry closet at all, it is necessary to ensure that there is always a certain amount of liquid on the valve (about 1 cm thick). This liquid works like a water lock to cut off possible odors.

After each emptying, it is necessary to wash the container, filling in a new portion, it must be loosened in order to wash all the walls. After that, processing will go more fully.

This dry closet for summer cottages is a mobile option. It fits in the trunk of a car, which is convenient. There is, however, an unpleasant moment: if the cottage is a periodic visit, it is impossible to leave a reservoir with liquid in an unheated room. Freezing can damage walls. Some people add non-toxic antifreeze (polypropylene glycol) to the processing liquid for the winter. Bacteria in such an environment are unlikely to survive, and for ammonium and formaldehyde, the yield is not bad. It is only necessary to dispose of such waste into the sewer.

Advantages and disadvantages

This dry closet for a summer residence impresses with the fact that it does not require a permanent installation. It can work anywhere, immediately after filling with liquids. Nothing more is needed for its work.

Cons - the need for refueling, it is, albeit not very big, but money. It is also necessary to monitor the presence of a certain supply of concentrates - without them (especially without what is poured down), the dry closet turns into an ordinary bucket with a lid.

But most annoying is the need to frequently empty the waste container. In any weather, at any time, if the tank is almost full, it has to be emptied. Otherwise, you cannot use the toilet. As a temporary option, this is a great choice.

Electric dry closets

A rare group. Works only when there is electricity. There are two types of electric bio toilets. In some, the liquid and solid fractions are separated. The liquid is discharged through a special tube that can be connected directly to the sewer or brought into the sewer. The solid fraction in a sealed container is incinerated. The rest is a small pile of ash that can be used as fertilizer.

The second type of electric toilets produces drying of feces and urine, the remains are then covered with a special composition. In this form, excrement weighs very little, and can be stored for a long time.

In order for drying or burning processes to be odorless, it is necessary to create or connect to ventilation, which adds to the complexity of the installation. Another common disadvantage of this type of dry closet is the dependence on electricity. Without it, nothing will work. The next significant disadvantage is the high price. All of them together limit the use of this type of aggregates.
