The organization of a traditional sewerage system operating on a gravity flow scheme is far from always possible. Especially when implementing projects of private country houses, it becomes necessary to use pressure lines that provide pumping of wastewater. Such a solution complicates the communication equipment, but in this case one cannot do without a special circulation activator. In technical terms, this problem is solved by a household sewer installation, which is small in size and has sufficient power potential to serve a specific network.
General information about sewer installations
In terms of their design, such units resemble pumping stations designed to work in specific conditions and with a specific carrier. The range of models is quite diverse, but even entry-level installations allow servicing highways located at a height of 5 m. Stations that are more solid in terms of capabilities are able to work with a 15-meter level. Also, modern models of such devices do not impose strict requirements on the configuration of the location of consumers - the distance from the connection point can reach 100 m. However,this distance depends on the power that the sewerage installation has in a particular design. Manufacturers supply such systems with additional functions. For example, it is advantageous to equip the same private houses with pumps, which include shredders. By means of cutting elements, the plant crushes and mixes the masses to be served, bringing them to a homogeneous state. This procedure facilitates further discharge of wastewater through pipes with small diameters.
The principle of operation of forced sewerage
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 effluents enter the tank, after which they can be subjected to grinding or other operations in preparation for a further stage of movement. The final stage involves the withdrawal of wastewater to the main line.
Usually for domestic needs, a compact sewer installation is used, the design of which allows it to be directly connected to modern plumbing. For example, in this way it is possible to organize the discharge of waste from a washing machine, toilet bowl, sink, from a laundry room, a bath room, etc.
Main selection criteria
There are two important parameters to consider in the selection process. The first concerns power and, accordingly, performance. The average power consumption is 3 kW, which allows the unit to serveabout 18-20 m3/h. The second selection criterion concerns the execution of the structure. Again, in its classic form, a surface sewer installation provides for two nozzles that provide input, as well as one output channel.
There are other configurations that should be correlated with the existing system both in terms of the number of channels and the dimensions of the station. For example, there are models that can even be placed in a drain tank, and there are also large-format units that require a separate place in the room for installation.
Installation of a sewer plant
Much in the technique of installation and connection of 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 also general principles of installation, in accordance with which a sewer installation can be installed qualitatively with your own hands and without the help of plumbers.
Work begins by connecting the inlet to the drain pipe from the target equipment. Further, the reverse side of the pumping station is brought to the main line, which will provide the output of wastewater. In both cases, it is important that the unit is initially located on a stable surface - for this you can also use the fasteners included in the station kit. If the installation and connection are done correctly, then you can turn on the unit in the electrical network.
Exploitation nuances
Modern sewage pumps are supplied or equipped with optional electronic control systems, so installation does not require special attention from the user. You can set the function of the unit to optimal operating parameters and operate as normal. But it is important to note that installations of this type can cause inconvenience due to high noise levels. Also, many users note vibrations that are distributed along walls and ceilings by sewer pumping units. Installation, made with the use of noise-absorbing materials, allows you to level the negative factors. If during installation this nuance was missed, then during operation it is recommended to place absorbent supports made of wood or soft plastic under the body.
Besides, in the process of operation, pumping stations require regular updating of filters. 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.
Reviews of Grundfos models
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 specially designed for operation in private households. A universal solution can be a sewer installation inSololift modifications. It is distinguished by a small mass and high throughput. But, as small home owners note, this option may be too powerful for entry-level communication systems.
Reviews of Wilo stations
Wilo equipment also demonstrates high quality. This product is also designed for household needs. For example, users praise the installations of the Drainlift series for the stable and trouble-free operation of the main working units and adjacent parts made of stainless steel. Units of this family are distinguished by high-quality work even in pumping aggressive environments. Of course, a sewerage installation of this class is not designed to serve chemically potent carriers, but it copes with hot liquids without problems. Also, the manufacturer Wilo wins over competitors due to the active implementation of security systems in 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 themselves to be reliable and durable, then Calpeda equipment attracts with its price. This does not mean at all that the performance of these products causes negative impressions for users, but more worthy options can be found on the market, again, under the brands Grundfos or Wilo. However, if you need a budget, but functional solution, then Calpeda systemssuit the best combination of these qualities. For example, for 15-20 thousand rubles. The company's customers have access to a modern sewer plant, reviews of which emphasize the stability of the pressure and the ability to work with drains whose temperature 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 maintenance of one bathroom or kitchen. Models of this type are valued by the owners for their small size, flexibility in installation and low maintenance.
Conclusion
No matter how good the sewerage station is, its performance indicators will also depend on other elements of the communication system. The same main pipes must not only correspond in size to the pump nozzles, but also meet the loads in terms of the throughput of the unit. The sewer installation shows the best results during operation in conditions of correctly adjusted connections. First of all, this concerns the pipes of the system. Also, professional plumbers recommend a careful approach to the calculation of the laying of pipes of the main highways. They should have a slight slope in order to reduce the load 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 it is necessary to plan the organization of such a system of channels even at the stage of building a house, and in this casethe very need to equip a forced system for removing wastewater may disappear.
