More recently, domestic problems associated with flooding inherent in living in private homes, were solved by the "grandfather" method. Dehumidification of the flooded cellar was made by improvised means with the involvement of all household members currently in the house. But now a strong and kind magician appeared under the name of "Drainage Pump" and began to pump out the water, gaily puffing his pomp. If your farm does not yet have a drainage pump, hurry to choose!

The right "drain"
Today, simply do not find such a private house or cottage, where no household drainage pump is used. The benefits of the pump can not be said.
Drainage pumps are widely used for the following purposes:
• pumping out cellars and cellars of leaked water
• Dehumidification of flooded areas or other areas
• for irrigation of garden beds.
What is the reason for the popularity of domestic drainage pumps?
Possessing low pressure characteristics, which are one of the main technical characteristics of equipment, drainage pumps still have solid indicators of the rate of liquid transfer. By what criteria should you choose a drainage pump, and at what price? By the way, our people very often travel around the world, advice - you can buy the right pump in his homeland.

Usually, machinery, tools, etc. purchased in the motherland of the manufacturer of better quality.
Which household pumps exist
Let's remind, that household pumps I distinguish on a direct purpose. There are the following types of domestic pumps:
• water
• drainage
• fecal.
Household water pumps are intended for water supply of a private house with water. Water pumps have significant water pumping performance and are sensitive to the presence of various mechanical impurities in the water.
The main purpose drainage household pumps is the transfer of contaminated water. Drainage pumps for dirty water are efficient even in the presence of mechanical impurities in the form of silt, sand or small particles of debris. Pumping of contaminated sewage without faeces is carried out in accordance with DIN EN 12050-2.
Fecal pumps are used for sewage systems, because pumps of this type excellently carry out in the able hands the transfer of significantly polluted water. This quality makes it possible to use faecal pumps instead of water or drainage systems from economically advantageous positions.
However, drainage pumps are considered to be the "golden mean" of sewage systems for private houses. Let us dwell in more detail on the types and application of drainage pumps.
Types of drainage pumps
main technical characteristics
Before choosing a brand of a drainage pump, it is necessary to clarify its main technical characteristics, namely:
• head
• Productivity.
Head this is the maximum height of the pumped water lifted by the pump. Therefore, the pump head is calculated taking into account the height difference, relative to the position of the working pump at the highest point. Recall that the head loss in the pipeline is 20 percent of the total length of the pipeline. It's sad, but this fact remains.
Productivity The pump is considered to be the volume of water that is pumped in a unit of time. It is recommended to choose a pump according to the "performance" parameter, taking into account the need for water. Common models, such as drainage pump wilo, have a capacity from 17.0 to 379.6 l / min.
The amount of water consumed must be at least 50 percent of the total consumption of all water intake points. However, such an amount can not exceed the debit of a water intake well.
types of drainage pumps: there is an immersion!
When choosing a drain pump, do not forget that there are the following types of drainage pumps:
• superficial
• submersible.
The choice of pump type will depend on the depth of the tank or the tank from which it is necessary to "draw" water.
Pump drainage surface
If the depth of the reservoir with pumping water is not more than 5 m, preference should preferably be given to a surface type pump. This choice will be justified by the ease of installation and operation of the pump, which consists in periodic cleaning of equipment.
Submersible Pump
The submersible drainage pump is designed for pumping dirty water (reservoirs, cellars, cellars, pits) with a depth of more than 5 meters.
Select the submersible pump according to the following parameters:
• for which working environment will the pump be used (dirty water, sewage with particulate matter, non-aggressive waste water)
• flow and pressure of water.
For example, grundfos drain pump the submersible is equipped with a standard discharge nozzle: TS 40 = Rp 1, TS 50 = Rp 1¼, TS 65 = Rp 2½, and also a hose connection.
To ensure good quality of the housing, submersible pumps are equipped with a metal or strong polymer reinforced with fiberglass. For automatic control over immersion, pumps are equipped with a float switch.
This eliminates the possibility of a "dry run". When choosing the equipment, preference is given to the drainage float pump. The principle of operation and the main characteristics are presented in the video.
How to choose a drain pump for a private house
The choice of a drain pump, intended for use in a private home, must be justified. To do this, decide on the following questions:
• for what specific purposes will the pump be purchased
• evaluate the quality and degree of water pollution
• estimate the feedrate and capacity of the equipment
• temperature of the pumped water (from 0 to + 35 degrees)
• material for manufacturing the drain pump
• the expected level of dehumidification.
It does not hurt to pay attention to the length of the power supply cord. For reference, most manufacturers are equipped with a pump of cords up to 10 m long. Take care of the availability of adapters of the appropriate diameter and hoses, because they will have to be purchased together with the main equipment.
