A piston dry closet is a type of chemical dry closet, whose action is based on the chemical processing of waste by reagents contained in water into an environmentally friendly fertilizer.

Chemical dry closets are classified according to the type of construction (mainly by the drain pump) into:

Types of pumps in reciprocating dry closets
  • Reciprocating, in which water for drainage has to be pumped up manually. This is the simplest system, you can repair and change the leaky parts yourself;
  • Pump (bellows), the pump of which is an accordion pump. Such dry closets are inexpensive models;
  • Electric, in which an automatic pump drains a fixed amount of liquid under strong pressure.

The upper part of the piston dry closet consists of:

Top container
  • Covers;
  • Seats;
  • Pump;
  • Water replenishment holes;
  • Clean water tank.

The lower part is somewhat more complicated and consists of:

  • Waste storage tanks; Image - DIY thetford dry closet pump repair Bottom container
  • Fullness indicator (not present on all models);
  • Connection valve and pressure relief valve;
  • Liquid storage niches;
  • Split valve stem;
  • Flush connection.

After flushing, the waste goes into a receiving tank with a special liquid for dry closets, which completely breaks them down.

Drainage in a piston dry closet is carried out due to pressure on the piston, previously brought to the uppermost position. The cocking and pressing procedure will need to be done every time. The amount of water used during flushing will depend on the pressure on the plunger.

Pumping liquid to drain with a piston pump

A bellows is called a device in the form of an accordion, which can easily and conveniently pump liquids. Its design is rather primitive and consists of several parts, which favorably affects the price of the device. As a rule, bellows pumps are made of plastic. They can be used regularly, or they can serve as a one-time option. What are the differences between bellows and piston dry closets?

Types of pumps for reciprocating dry closets

There are several main differences:

  • Possibility of dosing water for flushing (only has a piston type);
  • Self-repair (in the piston is possible, and in the case of the bellows, you will have to resort to the help of a qualified specialist);
  • Force application for flushing (piston only).

Thetford porta potti

The Thetford Campa Potti model can be safely attributed to the economy class among dry closets. All standard accessories for this type of dry closet are available, with the exception of the tank full indicator, so you need to be careful with this model. The water pump is presented as a hand pump. The height of the toilet is practically the same as usual.

The higher class will be the Thetford Porta Potti model, already equipped with a piston pump for flushing and a tank full indicator. The height of this model also corresponds to the height of an ordinary toilet bowl, which is usual for most people. It is very convenient, including for use in the country, so its popularity is only growing.

Thetford Porta Potti (model characteristics)

The developers of Thetford company noted and eliminated a number of shortcomings, improved the chemical dry closet, creating Thetford Porta Potti Excellence. For old models, a replacement came - after listening to the opinion of buyers, the creators made the seat slightly higher, and now its height is 46 centimeters (instead of the usual 40). The filling indicators are now located not only on the waste tank, but also on the water tank, which is extremely convenient.

In the event that the piston pump flush system fails, it is worth trying to replace it yourself, and if a similar problem arose with the bellows pump, you should contact a specialist to find out the causes of the malfunction and possible replacement of parts. It is not recommended to try to repair the bellows pump yourself, as the system is more complicated.

If you need to disassemble the upper part into smaller parts, you should try to find instructions for a specific model with a schematic designation of fasteners.

Liquid toilets perform the following tasks:

Filling liquid in a dry closet
  • Elimination of unpleasant odors;
  • Destruction of harmful microorganisms;
  • Improving flush efficiency;
  • Preventing the reproduction of microbes;
  • Waste splitting.

The dry closet liquids on the market can include:

  • Formaldehyde;
  • Biological substances;
  • Ammonium group.

Typically, liquids for this purpose are available in the form of concentrates. The substances included in their composition are capable of breaking down not only liquid, but also solid waste products of the human body, as well as toilet paper. One liter of such liquid is enough for ten refills on average.

In order to fill with sanitary liquid, you need to pour it into the upper tank using a special neck. With each flush, it will flow into the lower compartments. There are also liquids intended for the lower compartments. They will need to be added each time the lower compartment is cleaned.

Filling a portable dry closet

In order to fill the dry closet with clean water, you need to remove the upper part using a special bracket. The upper part is to be filled with the concentrate diluted in clean water, and the lower part is to be cleaned. The frequency of this procedure will depend on the volume of the storage tank of each specific model and its design.
