Sewage household pump: installation, features, advantages
Waste disposal is a delicate but extremely important topic.
Often, unwanted items get into the wastewater system: these can be leftover solid food, pieces of rags, bones, rich fat and other substances, objects and substances that complicate the normal flow of water and form blockages and traffic jams. In addition, as a result of alterations or design solutions, plumbing fixtures can be shifted from the sewer riser. To solve these problems, household pumps are used for pumping sewage, which we will tell you in more detail.
Features and Purpose
Description
In fact, and the principle of the device fecal pumps do not have fundamental differences from the drainage or submersible pumps. The unit creates a negative pressure in one way or another and pumps water at a certain pressure and with a corresponding capacity output.
The main difference is the presence of a special device, which with the help of steel or cast-iron knives is capable of shredding trash and unwanted objects that you accidentally found in your sink, bathroom or toilet.
Thus, we can distinguish three main functions of the device:
- Shredding large debris and bringing the working environment to normal values, allowing the system to work without failures and emergency conditions;
- Transportation of faecal matter or wastewater to the required distance, usually not more than 50 meters horizontally or 5 meters vertically. More powerful units provide significantly longer distances and performance;
- Protection of the pipeline and sanitary devices from sewage blockages and traffic jams, especially with regard to the kitchen sink and toilet.
Note! The pump allows you to significantly extend the life of expensive plumbing, significantly improve its operating conditions, save you from the not very pleasant procedures for cleaning siphons or pipes.
Purpose
- The purpose of sewage stations is, above all, the creation of comfort. You will not need to get rid of food debris in the dishes, filter the water with a special mesh, etc. In addition, the process of washing dishes is significantly accelerated.
- Another important function of the unit is to protect the internal surfaces of sewage pipes, as well as septic tanks and sewers from littering, and, as a result, breakdowns, the elimination of which is not only associated with unpleasant procedures, but also significant costs.
- It may be noted the possibility of using the device for the disposal of small organic household garbage, which is crushed and washed into the sewer system with water. Sometimes it is very convenient;
- Also, do not forget about the bathrooms and drains, which are below the level of the sewer pipe inlet. Here the thing is this: ordinary household systems work by gravity, so there should be a certain slope from the drain, but if the toilet or bathroom is installed in the basement or just below an adequate level, a pump is necessary.
Note! Based on the above, we can safely say that we face a modern multifunctional device that can not only improve the work of the sanitary part and sewage, but also significantly increase the comfort of our life.
Species
There are many ways to classify such devices, but we decided to choose the most substantially reflecting their technical data and purpose. So, experts are considering such major modifications of sewage pumps.
| Type of machine | Description | Power and scope | Installation and other features |
| Submersible | It works only if it is fully immersed in the pumped out working environment. Due to the aggressiveness of the working environment, the casing and main components of the machine are made of high-quality metals with special coatings. They have a large enough weight and size. | There is a variation in power: there are models for small country houses, and there are examples of devices for multi-storey cottages with a capacity of up to 40 kW, capable of providing a pressure of 20 meters and a capacity of 400 cubic meters per minute | Due to the immersion method and considerable weight, the device is mounted on a special steel cable, like well submersible units. Installing a high power do-it-yourself machine is risky and requires certain skills. Pumps of this type are often equipped with powerful cutting mechanisms capable of grinding solid large inclusions of up to 35 mm in diameter. Of course, the price of the device is relatively high. |
| Semi submersible | A distinctive feature of this unit is a special system equipped with a float mechanism, as a result of which the working and receiving parts are below the level of sewage, while the electric motor and other nodes are higher. This allows to extend the service life of the device and reduce the cost of protecting the case from leaks. Another, no less important feature of the pump is the absence of knives, but at the same time it is able to pump inclusions up to 15 mm in diameter | Semisubmersible sewage pumps have a relatively high capacity and cope with significant volumes of sewage and feces. Usually have a centrifugal pressure injection system, which ensures performance and reliability. | The installation consists in connecting the device to the sanitary systems, and in the working environment it is in “free floating”. It is also important to take into account the danger of closures and to treat the electrical part of the work extremely responsibly. Typically, such devices are used in homes where the basis of the effluent is fluid and faeces, since the lack of cutting does not completely protect the system from unwanted objects or fragments. |
| Surface | The name speaks for itself - the device is located on the surface and connects to the working environment exclusively through a pipe system. This is the most suitable model for domestic, domestic use, as in the conditions of the street closures, corrosion processes and other undesirable phenomena often occur, including the pump freezing and its failure. At the same time, the unit has a number of indisputable advantages: low weight, mobility, multifunctionality | The surface model has the lowest power. Such units are able to effectively deal with fragments of pollution of not more than 5 cm, which, in general, is enough in an apartment. Also do not forget about a much lower energy consumption and corresponding savings | May have a variety of ways to install and install inside other plumbing fixtures. Usually, simple models are set by consumers themselves according to the recommendations given by the instructions, and the seller sets up complex and non-standard ones |
Note! There is another kind of similar device, which is called the drainage pump, but this type has a slightly different purpose, device and characteristics. It is used for pumping out flooded premises and similar emergency works; it is able to cope with inclusions up to 35 mm and long fibers.
It should be understood that the pumping of flooding or accidental spills with conventional pumps is likely to lead to their early breakdown. Therefore, drainage pumps can be conditionally attributed to sewer models for special purposes.
Installation
In order to correctly establish the home model of a sewage pump, it is enough to follow a number of simple recommendations that we have prepared for you:
- The discharge pipe should have a slope of 1% of the length. The pipe itself is made of durable material - polypropylene, PVC or copper;
- Lifting is done at the beginning - no further than 30 cm from the outlet of the pipe from the pump;
- The bends of the pipeline must be smooth, right angles are divided into 2 parts of 45 degrees;
- The slope of the supply lines must have a slope of at least 3% of the length;
- Horizontal pipe sections of considerable length or laid below the pump level pipes are equipped with a valve 0.7 bar at the highest point for air to enter after switching off the device;
- Each pipeline has its own entry into the pipeline and does not intersect with other pipelines;
- For the possibility of repair and maintenance, the distance from the machine to the toilet should not be less than 40 cm;
- Do not install the device below the floor or in the pits for various purposes.
Tip! Use modern plastic pipes, as they are easier to install and have a system of fittings, while not inferior to the metal in performance.
Conclusion
A pump for pumping sewage and fecal masses is a necessary, convenient, and sometimes just a necessary thing. A single installation of such a unit will save you from a number of unpleasant problems. The video in this article perfectly demonstrates and confirms what has been said.
