Choosing liquid dry closets

Modern man is already accustomed to comfort, which should be present almost everywhere. If you have a summer cottage without a central sewerage system, and a stationary toilet on the street is extremely inconvenient, you can use a dry closet, which is installed in any room. Liquid toilets are the most common stand-alone options.

The construction of a chemical dry closet consists of 2 modules. The upper one consists of a water tank and a seat. The water in the tank is used for flushing. The lower module is a waste container, which is perfectly sealed, thanks to which there is no unpleasant odor. Some models have special indicators that inform the user about the fullness of the tank.

The principle of operation of a chemical toilet is based on the splitting of waste with special chemical concentrates. When they enter the excreta tank, the feces decompose and the odor is neutralized.

Let's take a look at a number of popular options.

Chemical and peat toilets are similar in external parameters. The difference is that there is absolutely no liquid in the peat bog, and an excellent fertilizer is obtained from the processed feces. Waste does not need to be disposed of in a special place, but can be immediately used as a biological additive for plants. The most important advantage of peat devices is the low cost of the filler; such a design can be created independently, unlike chemical dry closets.

Pay attention to a few nuances.

• To choose a suitable model of a dry closet, it is necessary first of all to determine the volume of the waste collection tank. The larger the tank, the less often you need to empty the container. The best option would be a model with a volume of 30-40 liters. The tank can only be serviced once a week.
• Compactness of dry closet is an important indicator, since its comfortable placement in a country house is very important. The larger the volume of the waste container, the larger the size of the device will be. Your choice should be based on the number of people who will use it. The smallest dry closets are designed for one person and have a tank volume of 10 to 15 liters.
• A very important factor is the size of the reagent reservoir. The larger it is, the less you will worry about its fullness.
• A useful function in some models is the water level indicator, which controls the filling of the tank. The device with an electric pump ensures an even distribution of the liquid along the drain.

Before using, pour clean water into the tank and add a special shampoo. Add 120 ml of sanitary liquid to the toilet bowl. Using the drain pump, pump 1.5 liters of water into the waste tank, then open the relief valve to allow the solution to flow into the lower faeces tank. Each time the reservoir is filled with clean liquid, raise and lower the pump several times until water begins to flow into the flush device. This is necessary in order to remove the airlock. Flushing occurs when the lever is lifted.

The design provides indicators that begin to show the level of filling only if the liquid has reached the level of 2/3. When the indicator reaches the upper mark, this means that the dry closet already needs to be cleaned.

To clean the dry closet from faeces, it is necessary to bend the latches and separate the containers. Thanks to the special handle, the lower container can be easily taken out. Before disposal, lift the valve up and unscrew the nipple to relieve pressure. After cleaning, rinse the reservoir with clean water.

With proper use, the biological toilet will last as long as possible.

• To make the device last as long as possible, always use a sanitary liquid that prevents bacteria from growing. Use a special shampoo to prevent water bloom in the reservoir and for disinfection.
• Be sure to lubricate the rubber gaskets in the pump and all moving parts of the toilet.
• To preserve the protective coating, do not use cleaning powders for washing.
• Do not leave liquid in the tank in an unheated room during the cold season for a long time, since when it freezes, it can break the tightness.
