The basements of a private or multi-family home are guaranteed to be protected from flooding if the installation of a drainage pump has been done properly. The consequences of breaks in the water supply network, heavy rains, clogging of the drainage system often lead to the development of an unsanitary situation in the house and accelerate the destruction of the foundation. Only a drainage pump can cope with a water spill.
Distinguishing Features
Dirty water pumping equipment belongs to the category of drainage, and its application is similar to the use of fecal pumps. However, there are some differences:
- To a greater extent, fecal units are designed for viscous wastewater with fibrous organic inclusions, for pumping which a grinding mechanism is provided.
- The drain pump, on the other hand, is not designed to operate in liquid conditions,saturated with organic inclusions. At the same time, the drainage pump for sewage allows you to pump wastewater containing insoluble large fragments - pebbles, sand, silt of a certain size. As a rule, the allowable inclusion size is indicated in the product data sheet.
Scope of application
The scope of drainage pumps is determined based on their design features:
- A series of prolonged rains, spring floods or heavy snowmelt. Such a situation can lead to the fact that the storm sewer system will not fully cope with its intended purpose, which will result in the flooding of cellars, basements of buildings, basement floors, etc. In this case, installing a drainage pump in the basement will allow emergency drainage work.
- This unit can be installed permanently 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 can be provided for the maintenance of artificial reservoirs. Without this unit, it is impossible to maintain the required filling level in an artificial reservoir, to perform periodic drainage to replace and clean water.
- Storage tanks for drainage or domestic sewage, storm collectors. Provided that they do not provide for independent drainage of liquid.
- In addition, installing a drain pumpcan be provided for discharging settled water into centralized collectors, natural reservoirs, filtration fields or pumping it into tanks for subsequent technological use.
- The current sanitary regulations prohibit even small car washes and workshops from operating without local treatment facilities. Dirty water is collected in primary sewers and sumps, and then the sewerage pump pumps it to the treatment plant tanks.
- 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 high-lying tanks.
Selection criteria
If you need equipment for pumping water from a pool, bath, well or any other container, then the best option would be a pump without a grinding mechanism. The main thing is not to use it in containers with large debris and polluted waters.
For kitchens and bathrooms, it is advisable to choose devices equipped with a cutting mechanism. Such devices perfectly grind objects that accidentally fell into the sewer system, thereby preventing it from clogging. The installation diagram of the drain pump with a chopper is shown below.
Anyway,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 easily cope with pumping wastewater, their performance is limited by the degree of contamination of the liquid. It is important that this parameter does not exceed the allowable values.
High content of sand, large stones, mud, silt may adversely affect the performance of this unit. That is, the installation of a drainage pump in the basement can be provided to eliminate flooding, but if it is necessary to drain the reservoir, a solid platform with a flat surface is placed under the bottom of the unit. If the scope of work is a construction site, 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 horizontally. In this case, the rate of liquid removal will be low, despite the fact that the drainage units operate in conditions of constantly arriving waters. In order for the installation of a drainage pump to be justified, it is necessary to add to the height of the sewage rise the length by which the discharge pipeline will be laid in a horizontal direction along the surface of the earth.
Selection of the unit
Selection should be carried out depending on where the drainage pump is planned to be installed (in a well, septic tank, basement, etc.).d.). 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 ingress.
In addition, the unit can be equipped with a vertical float mechanism that will start the pump as the recess fills, while the floor remains dry.
If you need maximum drainage of the tank, the installation of the drain pump in the well is carried out on a hard surface. In this case, the unit will start when the drains rise by a few centimeters.
Installation
Self-installation of a drainage pump in a septic tank must be carried out in compliance with certain rules. For example, it is not allowed to install equipment intended for wells in septic tanks, and vice versa. Despite the external similarity, the models have different power ratings and operating principles.
It is also not recommended to work with budget options like "Baby" or "Brook" 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 instructions
- First of all, you need to find a pressure pipe at the pumping unit, to which the pipeline is connected, through which wastewater will be pumped out. Carefully at the junctionthe clamp is tightened with a screwdriver or pliers.
- Most models are equipped with a float switch. If it is present in the model you have chosen, then a check valve should be installed on the connected pressure hose, which will prevent water from flowing back into the tank.
- Immediately before installation, you need to check the operation of the unit. Carefully study the instructions for it, manufacturer's recommendations and certificates. Another important point is to determine the direction of the shaft. To do this, a household drainage pump is installed on a table or on the floor and connected to the network. If the movement is to the right, then the equipment is working correctly.
- Installation of the pump unit must be carried out exclusively in a vertical position. Make sure that the pressure hose is also directed vertically. Its end is sent to a container where the liquid will subsequently be pumped.
- Finally, the pump sinks to the bottom of the tank and connects to the mains.
Cleaning the well
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 wastewater.
- Destruction of outgrowths of moss, silt and other contaminants present at the bottomtank.
- Cleaning the filter.
On average, cleaning a well takes 1-2 weeks.
Installing a drain pump on an air conditioner
The air conditioner emits a large amount of condensate during operation, which must be removed outside the room. For these purposes, the drainage of the air conditioner is organized, which includes a drainage route, trays for the accumulation of condensate and a drainage pump.
Each equipment requires a pump of a certain capacity, which must significantly exceed the rate of condensate formation. The power or performance of the pump is determined in l / h, however, it is important to take into account its ability to lift liquid, noise level and other characteristics.
The pump can be mounted in many 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, and so on. In other words, each pump has its own performance. Based on this, it becomes clear at what distance from the indoor unit it can be fixed.
