The basement of a private or apartment building is guaranteed to be protected from flooding if the installation of the drainage pump was performed properly. The consequences of breakthroughs of the water supply network, torrential rains, and clogging of the drainage system often lead to the development of an unsanitary situation in the house and accelerate the destruction of the foundation. To cope with a spill of water is only capable of a drainage pump.
Distinctive features
Dirty water pumping equipment belongs to the category of drainage, and its use is similar to the use of fecal pumps. However, there are some differences:
- To a greater extent, fecal aggregates are designed for viscous effluents with fibrous organic inclusions, for the pumping of which a grinding mechanism is provided.
- The drain pump, on the contrary, is not designed to operate in a fluid saturated with organic impurities. At the same time, a drainage pump for sewage allows pumping drains containing insoluble large fragments - pebbles, sand, silt of a certain size. As a rule, the allowable size of inclusions is indicated in the product passport.
Scope of application
The scope of the drainage pumps is determined based on their design features:
- A series of lingering rains, spring floods or heavy snowmelt. Such a situation can lead to the fact that the storm sewer system will not cope with its destinations to the full, which will result in flooding of cellars, basements of buildings, basement floors, etc. In this case, the installation of a drainage pump in the basement will allow for emergency drainage work .
- This unit can be installed on a stationary basis in the basement. A properly configured automation system will control the level of incoming groundwater and keep the room dry.
- Also, the installation of a drainage pump may be provided for the maintenance of artificial reservoirs. Without this unit, it is impossible to maintain the required fill level in an artificial reservoir, to periodically drain to replace and clean the water.
- Storage tanks for drainage or domestic sewage, storm collectors. Provided that they do not provide for independent drainage of liquid.
- In addition, the installation of a drainage pump may be provided for discharging the settled water into centralized collectors, natural reservoirs, to filtration fields or pumping it to tanks for subsequent technological applications.
- Existing sanitary rules prohibit even small car washes and workshops without local treatment facilities. Dirty water is collected in primary collectors and pits, and then a drainage pump for sewage pumps it into the tanks of treatment facilities.
- These devices are actively used for irrigation agricultural work, they pump liquid from artificial and natural reservoirs to irrigated areas.
- This equipment is characterized by its versatility, it can be used not only for dirty, but also for clean water in autonomous water supply systems, filling highly located containers.
Criterias of choice
If you need equipment for pumping water from a pool, bathtub, well or any other container, then the pump without a grinding mechanism will be the best option. The main thing is not to use it in containers with large garbage and polluted waters.
For rooms in kitchens and bathrooms, it is advisable to choose devices equipped with a cutting mechanism. Such devices perfectly crush objects that accidentally fall into the sewage system, thereby preventing its clogging. The installation diagram of a drainage pump with a grinder is presented below.
In any case, when purchasing equipment, it is important to focus on a number of requirements, which are listed below.
Working conditions
Despite the fact that drainage pumps can easily handle wastewater pumping, their technical characteristics are limited by the degree of liquid contamination. It is important that this parameter does not exceed acceptable values.
The high content of sand, large stones, mud, silt can adversely affect the operation of this device. That is, the installation of a drainage pump in the basement can be provided to eliminate flooding, but if you need to drain the pond, a solid platform with a flat surface is placed under the bottom of the unit. If the construction site is the front of the work, then a powerful fecal pump with a grinding mechanism will be the best option.
Arithmetic calculations
When calculating the required power of pumping equipment, it is important to consider that 1 meter of vertical length corresponds to 10 meters of horizontal. The rate of fluid drainage will be low in this case, despite the fact that the drainage units operate in conditions of constantly arriving water. In order for the installation of the drainage pump to be justified, it is necessary to add to the height of the sewage rise the length by which the outlet pipe will be laid horizontally along the surface of the earth.
Unit selection
Selection should be carried out depending on where it is planned to install a drainage pump (in a well, septic tank, basement, etc.). It is advisable to install equipment of this type in a pit with a depth of 400 to 600 mm. This will protect the basement from water.
Additionally, the unit can be equipped with a vertical float mechanism that will start the pump as the cavity is filled, while the floor will remain dry.
If maximum drainage of the tank is necessary, the installation of a drainage pump in the well is carried out on a solid surface. In this case, the unit will start when the sewage is raised by several centimeters.
Mounting
Self-installation of the drainage pump in the septic tank must be carried out in compliance with certain rules. For example, in septic tanks it is not allowed to install equipment designed for wells, and vice versa. Despite the resemblance, the models have different permissible power and principle of operation.
It is also not recommended to work with budget options such as "Kid" or "Trickle" and others - they cost a penny, but at the same time they are characterized by poor build quality. After pumping out the entire volume of water, they do not turn off, unlike models such as Makita, Gardena, Alco, Grundfos or Profer.
Step-by-step instruction
- First of all, it is necessary to find a discharge pipe at the pumping unit, to which a pipeline is connected, through which sewage will be pumped out. At the junction, the clamp is neatly tightened with a screwdriver or pliers.
- Most models are equipped with a float switch. If it is present in the model of your choice, a check valve should be installed on the connected pressure hose to prevent water from flowing back into the tank.
- Immediately prior to installation, check the operation of the unit. Carefully read the instructions for it, manufacturers' recommendations and certificates. Another important point is the determination of the direction of the shaft. To do this, the household drainage pump is installed on a table or on the floor and connected to the network. If the movement is carried out in the right direction - it means that the equipment is working correctly.
- Installation of the pump unit must be carried out exclusively in an upright position. Ensure that the pressure hose is also directed vertically. Its end is sent to a container, where liquid will subsequently be pumped.
- And finally, the pump sinks to the bottom of the tank and connects to the mains.

Well cleaning
To make the process of cleaning the well as simple as possible, it is recommended to purchase a special float, with which the water level will be determined. Despite the fact that a device of this type operates in automatic mode, it is advisable to monitor the process of its operation. It consists of the following steps:
- Pumping of drains.
- Destruction of growths of moss, silt and other contaminants present at the bottom of the tank.
- Filter cleaning.
On average, cleansing a well takes 1-2 weeks.
Install the drain pump on the air conditioner
During operation, the air conditioner emits a large amount of condensate, which must be removed outside the premises. For these purposes, drainage of the air conditioner is organized, which includes a drainage route, trays for accumulating condensate and a drainage pump.
Each equipment requires a pump of a certain capacity, which should significantly exceed the rate of formation of condensate. The power or productivity of the pump is determined in l / h, however, it is important to consider its ability to raise the liquid, noise level and other characteristics.
The pump can be mounted in a variety of ways. Therefore, in this case, it is important to pay attention to the height of the lift. One pump is capable of lifting liquid to a height of 3 meters, the other to 4 meters, etc. In other words, each pump has its own characteristics. Based on this, it becomes clear at what distance from the indoor unit it can be fixed.
