The dwelling can be considered comfortable when it is electricity and water. But if there is no sewer in the house, then the owner faces a serious problem. The fact is that the drains are not handled by municipal services, but by the owners themselves. They have to organize an autonomous sewage system, digging a well in the ground or installing an airtight container. However, both eventually fill in, and there is a new problem - pumping out the content. Most often hire a special sewer machine, whose challenge can be felt from time to time in a pocket. In this case, it is more rational to use a sewage pump in a private house.
How does the sewage pump work?
A drainage pump, or a faecal pump, is a device that can pump a very dirty and viscous liquid or water containing solid and long-fiber substances. When pumping water, the pump processes solid inclusions (for example, paper, food waste, hair, hygiene products, feces) with a cutting device (knife, cutting edge) and then pours everything to the surface.
There are also pumps for drainage and sewerage - drainage devices used for pumping water from mines, cellars, pools , pipelines and drain pits. However, they are not capable of passing solid particles larger than 5 cm, since the suction branch of the lower part of the device does not exceed this size.
How to choose a drainage pump for sewage?
When buying a sewer pump for a private house, it is important to take into account several points: design features, the ability to work with hot liquids, power, etc.
Pumps are divided according to the design features. Submersible devices made of strong metals (cast iron, stainless steel) are completely lowered to the bottom of the reservoir or pit. This is an average power unit (40-60 kW), capable of quickly pumping waste water to a height
15-45 m and grind solid particles up to 8-10 cm in size. They are most often used as pumps for dachas and for the toilet.
Semi-submerged products are lowered due to the float only half: the engine is located on top of them, and the pump itself is below the surface of the water. Such a pump is not equipped with a chopper and can suck in particles with a maximum size of 1.5 cm. A semi-submerged pump is used to clean small cesspools or waste pits.Surface aggregates are not at all immersed in water: they are located on the edge of the pit, only the hose is immersed in the drain. This is a good version of the sewage pump for the kitchen and bath, since the diameter of the suction nozzle does not exceed 0.5 cm. The advantages of such a product include mobility, low cost and ease of installation. However, at the same time the device can not be used outdoors in the cold season, and its power is low (30-40 kW).
If you have to install a pump to pump not only cold but also hot water in the presence of a dishwasher or washing machine at home, you should choose a device that can withstand the temperature of the liquid to 90-95 degrees. Such aggregates are found both with a chopper and without it.
An equally important indicator can be considered performance: for a private house it is optimal to choose a model with a parameter of 15-20 m3 per hour. In the market of drainage devices, the sewage pumps of the Sololift series from German company Grundfos, which are used for various household needs, are popular. A good operating life of the products from the German Vortex and the Spanish Vigicor ESPA. Domestic models are popular "Drenazhik" and "Irtysh", which, despite their low price, invariably delight consumers with durability and reliability.
