The organization of a traditional sewage system operating according to the gravity flow pattern is far from always possible. Especially when implementing projects of private country houses, there is a need to use pressure pipelines, which provide pumping of effluents. This solution complicates the communication equipment, but without a special activator of circulation in this case can not do. In technical terms, this problem is solved by a domestic sewer installation, which is small in size and has sufficient power potential to service a particular network.
General information about sewer installations
In their arrangement, such units resemble pumping stations designed to operate in specific conditions and with a specific medium. The range of models is quite diverse, but even entry-level installations allow servicing highways located at an altitude of 5 m. More solid stations are capable of operating at a 15-meter level. Also, modern models of such devices do not impose strict requirements on the configuration of the consumers ’location - the distance from the connection point can reach 100 m. However, this distance depends on the power available in a particular sewer installation. Manufacturers provide such systems with additional functions. For example, it is beneficial to equip the same private houses with pumps, which include shredders. By means of cutting elements, the unit crumbles and mixes the serviced masses, bringing them to a homogeneous state. This procedure facilitates the further discharge of effluents through pipes with small diameters.
The principle of operation of forced sewage
In the traditional version, the installation is a pump, which includes a check valve. The principle of operation is built according to the same scheme as in areas with irrigation systems. Through two nozzles, inlet drains enter the tank, after which they can be subjected to grinding or other preparation operations for the next stage of movement. The final stage involves the withdrawal of effluents into the main highway.
Typically, for domestic needs, a compact sewer installation is used, the design of which allows the possibility of its direct connection to modern plumbing. For example, in this way it is possible to organize the discharge of drains from a washing machine, toilet, sink, laundry, bathhouse, etc.
Key selection criteria
In the selection process, two important parameters should be considered. The first concerns power and, accordingly, performance. The average power consumption is 3 kW, which allows the unit to serve about 18-20 m 3 / h. The second selection criterion relates to the design. Again, in a classic form, a surface sewer installation provides for two pipes providing input, as well as one output channel.
There are other configurations that should be correlated with the existing system both in the number of channels and in the dimensions of the station. For example, there are models that can be placed even in the drain tank, but there are also large-format units that require a separate place in the room to be installed.
Sewer installation
Much of the technique for installing and connecting equipment depends on the purpose of the model. So, there are special units for bidets, showers, toilets, etc. In each case, the sequence of installation operations can be individual. But there are general principles of installation, according to which a sewer installation can be installed with high quality with your own hands and without the help of plumbers.
Work begins with connecting the inlet to the drain pipe from the target equipment. Next, the reverse side of the pumping station is led to the main line, which will ensure the discharge of effluents. In both cases, it is important that the installation is initially located on a stable surface - for this, you can also use the fasteners included with the station. If the installation and connection are correct, then you can turn on the unit in the electrical network.
Operation Nuances
Modern sewage pumps are supplied or optionally equipped with electronic control systems, so installation does not require special attention from the user. You can adjust the function of the unit to the optimal operating parameters and operate in normal mode. But it is important to note that installations of this type can be inconvenient due to the high noise level. Also, many users note vibrations that spread along the walls and ceilings of sewage pumping units. Installation made with the use of sound-absorbing materials allows to neutralize negative factors. If during installation this nuance was missed, then already during operation it is recommended to lay absorbing supports made of wood or soft plastic under the body.
In addition, during operation, pumping stations require regular filter updates. Therefore, it is important to change the absorbent in a timely manner, which is usually activated carbon - it should be placed in the capacity of the cleaning container.
Grundfos Model Reviews
The German manufacturer enjoys great confidence among Russian summer residents who widely use pumping equipment. Sewer stations of this brand are also highly valued for their small size, sufficient performance and reliability. In particular, the Conlift and Multilift models are specifically designed for use in private home ownership. A universal solution can be a sewer installation in the Sololift modification. It is distinguished by its light weight and high throughput. But, as owners of small houses note, this option may be too powerful for entry-level communications systems.
Wilo Station Reviews
Wilo equipment also demonstrates high quality. These products are also designed for domestic needs. For example, users praise the Drainlift series for the stable and trouble-free operation of the main work units and related parts made of stainless steel. Units of this family are distinguished by high-quality work even in pumping out aggressive media. Of course, a sewer installation of this class is not intended for the maintenance of chemically strong carriers, but copes with hot liquids without problems. Wilo also outperforms its competitors by actively integrating safety systems into its pumps. Owners, for example, note the benefits of built-in overload protection.
Calpeda Pump Reviews
If the stations of the above manufacturers have proven their reliability and durability, Calpeda equipment is attractive for its price. This does not mean at all that the performance of this product is causing users a negative impression, but more worthy options can be found on the market, again, under the Grundfos or Wilo brands. However, if you need a budget but functional solution, Calpeda systems will suit you with the optimal combination of these qualities. For example, for 15-20 thousand rubles. the company's customers have access to a modern sewage system, reviews of which emphasize the stability of the pressure and the ability to work with effluents, the temperature of which reaches 50 ºC. But in terms of power and performance, this is a rather modest option. Such installations are suitable for small houses or targeted service of one bathroom or kitchen. Models of this type are appreciated by the owners for their small size, flexibility in installation and low maintenance.
Conclusion
No matter how good the sewer station is, the performance indicators will depend on other elements of the communication system. The same main pipes must not only correspond to the pump nozzles in terms of size, but also meet the loads in terms of the unit's throughput. The sewer installation shows the best results during operation in conditions of correctly adjusted connections. First of all, this applies to the nozzles of the system. Also, professional plumbers recommend carefully approaching the calculation of the laying of pipes of the main highways. They should have a slight slope in order to reduce loads on the sewer station. A competent calculation of these parameters will optimize the operational life of the unit, as well as increase its efficiency. Another thing is that the organization of such a system of canals should be planned at the stage of building a house, and in this case the necessity of arranging a compulsory sewage removal system may also disappear.
