It is important not only to properly install the sewer pipes and connect them to the septic tank. It is necessary that the drains leave in a sump in a timely manner and not create problems in the form of an unpleasant smell in the house. In some cases, it may be necessary to install a sewage pumping station for domestic wastewater. Pumps are different in design, power, method of operation. Before going to the store, you need to have some ideas about these units in order to ask the right questions to the manager. You may need to bring a sewer line plan to find a pumping station that meets all the requirements.
The purpose of the pumping station for a private house
A sewage pumping station for a private house is an additional device that consumes electricity, so residents try to equip gravity-fed systems so as not to pay too much. This is possible in cases where the septic tank is located below the house, and the pipes can be laid under a slope, since the length of the trunk is small.
If for some reason the sewage pit is higher than the house, the waste will not be able to flow independently. The bathroom can be located in the basement, so the drains must first be raised, and then they will go into the main pipe and then will flow independently. The same situation when there is an obstacle in the way of sewer pipes. The close location of groundwater does not allow to comply with the required slope, so the section of the highway is forced to be located vertically. In all these cases, it is necessary to create increased pressure so that the liquid does not stagnate in the pipes. In winter, this can lead to the formation of ice plugs and it will be impossible to use sewers.
Wastewater contains large particles, which at a low speed of movement accumulate in the pipe and block it. This happens in those areas where the highway turns or its diameter changes. On a difficult terrain, it is difficult to lay pipes in a straight line - you have to go around buildings or obstacles.
The principle of operation and main components
Sewage pumping stations can be divided into domestic and industrial. Industrial devices are complex engineering equipment that does not make sense to install in home systems, since their performance far exceeds the volume of a private house.
For private buildings, units of medium complexity are provided. They have small dimensions and compact dimensions. The type of drains is taken into account - waste from the toilet containing large particles, kitchen waste and drains after the washing machine usually fall into the home sewer.
SPS consists of the following main nodes:
- a pump or several units of a similar type;
- storage tank.
The pump can be installed directly at the exit from the house or behind the toilet. Such mini-models have a neat appearance and fit well into the interior of the bathroom.
The storage capacity can be compact in size or designed for a whole multi-storey building or even a village.
The principle of operation is as follows: the liquid coming from plumbing devices is collected in a storage tank. Upon reaching a certain level, one or more pumps are triggered and drains are discharged into sewer pipes. The process is automated, so there is no need to constantly turn on the equipment.
Pipelines are equipped with check valves so that odor and liquid cannot get back into the house. The garbage lingers in the pickup basket, from where it is taken out during maintenance and scheduled cleaning.
The station can operate in three modes:
- at normal times, when the amount of effluent does not exceed the norm, one pump is triggered;
- at rush hour, when all residents of the house use water, both pumps or all units that are inside the storage tank are turned on;
- emergency mode - in the event of a large amount of water or failure of both units, a warning signal is activated that the station is not coping with the load.
Manual control is also possible, in which the start-up of the pumping equipment is done by pressing a button.
Types of KNS for a private house
Mini devices are installed behind the toilet or at the exit from the house, from where the pump pump pumps sewage into the septic tank. This is a small device in a plastic case, imperceptible and low noise. It is based on submersible mechanisms with a cutting element or without it.
The second type of KNS is larger and more powerful. It is a septic tank with a submersible pumping mechanism, which turns on when it is necessary to clean the tank and direct the drains to the city sewer or sewage machine.
The third option is the most common. This is a stationary device equipped with 2 to 3 submersible pumps, which discharges effluents outside the house into a drain hole. From there, with the help of fecal aggregates, the fluid is pumped to the next septic tank for filtration through the soil.
Criterias of choice
To drain the drain fluid from the house, a small stationary model is installed. Its power should be comparable with the number of points of water use - a bathtub, a toilet bowl, a washing machine or a dishwasher, sinks, a pool or a bathhouse. Selected by the parameters of power and volume of the storage tank. It is better if the pump station is equipped with two pumps.
For the functioning of the sewer of a multi-storey building, a large storage tank and several units that will pump out the liquid will be required. An important point is the presence of a cutting mechanism. Better when it is, as debris and large waste can clog the exhaust pipe.
Settlement
When buying a complete SPS, there is no need to buy a very expensive device that will work at 10% of the declared capacity. Choose a station based on the following indicators:
- the size of the equipment - should be suitable for the room in which the installation is planned, for a private house it will be a regular household appliance, which can be placed on an area of 1 square. m;
- the expected flow of waste fluid - depends on the number of residents and the volume of water consumed during rush hour;
- distance by which liquid must be removed;
- inlet and outlet pipe heights;
- performance of the equipment based on the degree of pollution of effluents.
KNS household can be independently connected, while overall devices are formed of several parts designed for specific working conditions.
Mounting Features
You can install and connect household SPS by following the instructions. These are “sololifts” that are placed near plumbing fixtures. They are compact and do not require special skills. The instructions step by step indicate the actions that need to be performed.
Another thing is to establish a sewer station for a country house. For these works it is better to invite professional masters. Accuracy and proper selection of components, as well as their final adjustment are important here. The sequence of actions is also important. A person who does not have experience and does not understand the nuances of the devices will not be able to carry out the installation correctly and will lose the manufacturer’s warranty.
Operation and maintenance
Maintenance of domestic stations located in the house should be carried out regularly.Pump clogging is possible if it is not equipped with cutting blades. The work is performed by a specialist service center. If you carefully monitor its actions, later it will be possible to carry out inspection and cleaning of the unit yourself.
The pumping station of a private house also requires regular maintenance, but it is forbidden to go down into the sewage tank yourself. Poisonous gases can cause loss of consciousness and death by suffocation.
Advantages and disadvantages of the KNS
The advantage of SPS is that it improves the operation of the entire sewer system, eliminating odors and preventing the reverse movement of effluents. At the same time, the equipment needs frequent maintenance, which involves financial investments.
Prices for sewage pumping units are high. The cost of the device depends on the brand of the manufacturer, the materials from which the main components are made, as well as the complexity of the design. Properly installed equipment lasts about 10 years. Cheaper devices from unknown manufacturers are much smaller.
