A vital place in the house or in the country is the toilet. In remote regions, where there is no centralized sewage system, and there are problems with waste disposal, a dry closet comes to the rescue. Such a modern plumbing device has several advantages over a traditional cesspool. The main one is ease of use and reasonable price. Today, the range of biological toilets on the domestic market is quite wide. With the help of experts, summer residents will be able to choose the most efficient and comfortable model.

How to choose a dry closet

1. Types of dry closets. There are three types of waste disposal method. These are electrical, chemical and dry (composting) models. Each species has its own strengths and weaknesses.
2. Storage tank volume. Since the human bioorganics is not removed anywhere from the toilet, as is the case with the usual toilet, the volume of the storage tank becomes an important characteristic of the dry closet. First of all, you should consider the number of residents who will use the device. If for lonely summer residents there is enough for a season a tank with a capacity of 40-50 liters, then a 100-200 liter drive is capable of serving a full-fledged family of 4 people.
3. The weight of the filled tank. When the time comes to clean the dry closet, the user will face such a problem as the large weight of the tank. Some manufacturers equip large containers with wheels, smaller tanks have handles. For older people, it is preferable to choose the lightest model (up to 15 kg).
4. Full indicator. For timely cleaning of the storage container, many dry closets have full indicators. This useful function helps to avoid unpleasant “overload” with all the ensuing consequences.
5. Toilet seat height. An important characteristic for children and the elderly is the height of the dry closet seat. The standard value is considered to be the limit from 40 to 45 cm.
6. Drain method. After each trip to the dry closet, it is necessary to carry out a conditional drain. In some models, a piston pump is used, in other devices an electric pump is installed for this, and in dry products, peat chips are sprinkled.
7. Ventilation. Effective ventilation is a necessary option for every dry closet. It allows you to remove unpleasant odors to the outside. It is important not only to choose a system with a certain height and throughput, but also not to forget about such anti-fly elements as a net.

The composting device does not just dispose of human waste products, but makes them nutritious humus for plants. A dry toilet is easy to use, it will serve the owner for a long time, justifying a large initial investment. The Finnish model does not require a water or electricity connection. Thanks to the cleverly insulated design, composting takes place quickly and efficiently. Experts highly appreciated the capabilities of the dry closet, giving it first place for a spacious tank (200 l) and receiving compost in 6-7 weeks.

Users note such advantages of the model as workmanship, lack of smell and ease of use. The disadvantage of the product is the high price.

Advantages

• high price.

Kekkila Ekomatic

Tandem Compact-Eco

Rating: 4.7

The peat toilet Tandem Compact-Eco is in stable demand among Russian summer residents. The model attracts buyers with its democratic price, durability of the polystyrene case and low weight (12 kg). The large diameter of the ventilation pipe effectively removes unpleasant odors to the outside. Tandem Compact-Eco is inferior to the leaders of our rating in the volume of the lower tank (60 l), so the device is optimal for 1-2 summer residents who spend the warm season on their personal plot. There will be no problem with removing compost, the removable tank is equipped with carrying handles.

Users liked the quality of the materials used, the absence of odor and the environmental friendliness of the dry closet. Many consider the disadvantage of the model to be the unfortunate location of the nozzle for removing liquid.

Advantages

• affordable price;
• high quality plastic;
• effective ventilation;
• convenient removable tank.

disadvantages

• the drain connection is poorly located.

Piteco 905

Rating: 4.6

The composting dry closet Piteco 905 stands out from the competition with its original design. The manufacturer equipped it with a pair of small wheels. Each of the 4 walls of the case has recessed handles, which makes the movement of the product easy and convenient. The developers took this step because of the capacious tank (120 l), after filling which the light model (12 kg) will turn into a rather weighty load. A 75 mm ventilation pipe is used to remove unpleasant odors. It can be quickly detached from the case when it comes time to empty the compost. The toilet comes with a 30-liter bag of peat.

The model is one step away from the top three in the ranking for a number of reasons. Users complain about the lack of a protective mesh from flies, and there is not enough fungus on the ventilation pipe.

Advantages

• big sizes;
• easy installation;
• no odors;
• ease of movement.

disadvantages

• no protective mesh and fungus.

Piteco 506

Rating: 4.5

The advantage of the Piteco 506 dry closet is not only environmental friendliness, but also frost resistance. Therefore, summer residents can safely leave the product in an unheated building for the winter. The model copes well with removing unpleasant odors, for effective ventilation there is a 2-meter pipe included in the kit. Through the drainage hole, the liquid fraction can be removed quite inconspicuously into a container or sump. In order to evenly fill the waste with peat crumbs, the manufacturer equipped the dry closet with a rotary handle.

The experts included this product in our rating for affordability. But in terms of the capacity of the lower tank (44 liters), it is clearly inferior to its competitors. You will have to take out the filled container more often, it's good that handles are provided for convenience.

Advantages

• affordable price;
• effective odor removal;
• uniform scattering of peat;
• frost resistance.

disadvantages

• small tank volume;
• large weight (20 kg).
