Installation of a sewage pump for sewage pumping by one's own hands

Waste management is a delicate, but very important topic. Often unwanted objects enter the sewer system: it can be abundant fat, bones, pieces of rags, remnants of solid food and other substances, substances and objects that form plugs and clogs, and also complicate the optimal water flow. In addition, as a result of design decisions and re-planning, the plumbing equipment can be shifted from the sewer pipe. Solve all this problems will help install a fecal pump.

Basic Groups

There are several types of sewerage equipment of this type. The absence or presence of a grinding mechanism, the type of construction, the temperature of the pumped-out effluent and the method of installation are taken into account.

Equipment for cold drains without a chopper

The fecal pump for sewerage, designed for pumping cold currents, without a chopper, compared to other varieties of these devices, is the most inexpensive. It is designed to pump liquid from the pool or clean water, for example, groundwater, flooding during the spring flood basements. The maximum temperature of the effluent must not exceed 40 ° C.

Pump for hot drains without chopper

The fecal sewer pump, which is designed for pumping hot runoff, without a grinding mechanism, is able to pump liquid without solids at a temperature of 90 ° C. Such drains are characteristic for baths and saunas.

A device for cold drains with a shredder

The pump for pumping cold domestic waste water with a chopper is the most popular type of equipment of this type. By installing this fecal toilet pump, you can cope with all the impurities: paper particles, hair, hygiene products (cotton pads, tampons, etc.) easily break up into small particles with a cutting mechanism, and then, together with contaminated water, are pumped out. Pumping equipment is designed for a temperature of no more than 40 ° C.

Pump for hot run-off with chopper

The device for pumping hot runoff with a grinding mechanism in structure resembles the previous faecal pump for the toilet, but it is capable of moving sewage with a temperature of not more than 90 ° C. This is the most optimal option for baths equipped with a bathroom. Continuous use of this equipment will avoid clogging in the sewage system.

Varieties

Before selecting a faecal pump with a chopper or without it, it is important to find out for what purposes you need this equipment. The domestic sewage system can have several varieties. There are many options for classifying devices of this type, so it is worth considering those that substantially reflect their purpose and technical data.

Submersible

The fecal pump for pumping the sewerage functions only when fully immersed in the pumped out working environment. The body of the unit and its main components, because of the aggressive working environment, are made of high-quality materials and covered with a special composition. For this pumping equipment, the characters are large in size and weight.

There is a wide variation in power: it is possible to install a fecal pump at a dacha or in a small house, and there is equipment for multi-storey buildings with a capacity of up to 40 kW and a capacity of 400 m ³ per minute.

Due to the immersion method and large mass, the pumping equipment is fixed to a special steel cable - similar to downhole submersible devices. Self-installing a high-capacity fecal pump is a risky procedure that requires certain skills. Very often, these devices are equipped with a powerful cutting mechanism capable of grinding large solid inclusions up to 35 mm in diameter. Naturally, the cost of such equipment is quite large.

Semi-submersible

A distinctive feature of this device is an especial system that is equipped with a float mechanism, afterwards its workings the water intake and working parts are located below the level of sewage, while the electric motor and other nodes are higher. As a result, the cost of protecting the housing from leaks is reduced and the service life is extended. Another important feature of this faecal pump for pumping sewerage is the absence of knives, but it pumps up inclusions up to 15 mm in diameter.

Semi-submergible aggregates have quite high capacity and cope with large volumes of faeces and sewage. As a rule, they are equipped with a centrifugal pressure injection system, which ensures reliability and productivity.

The installation of a fecal pump consists in its connection to plumbing systems, in the working environment it is in "free floating". In addition, it is necessary to take into account the danger of short circuits and take special responsibility to connect to the mains. Such devices are usually installed in houses where feces and liquids form the basis of drains, since the absence of a cutting mechanism will not allow the sewage system to be protected from getting unwanted fragments and objects.

Surface

In this case, the name speaks for itself - the pumping equipment is on the surface, and its connection to the working environment is carried out only through the pipeline system. This is the most suitable option for internal use, since in street conditions, short-circuits, corrosion processes and other undesirable phenomena often occur, up to the failure of the unit. At the same time for such equipment is characterized by a number of undeniable advantages: multifunctionality, mobility and low weight.

The unit of this type is characterized by low power. It is able to effectively fight pollution with a size of no more than 5 cm. For the conditions of an apartment this is enough. Also, do not forget about the low consumption of electrical energy and subsequently significant savings.

Installation of a fecal pump can be very diverse. Simpler models consumers install independently in accordance with the recommendations specified in the instruction, and installation of non-standard and complex devices should preferably be entrusted to specialists.

Fixed mounting

Pumping equipment of this type is operated in a stationary mode if pumping of sewage into a septic tank located in accordance with sanitary standards is required, at a distance from the residential house not less than 15 meters from the water well - at least 50 meters.

Another application of the pump is the need for forced pumping out of drains into the main sewage system, when the system is located above the level of the house, and the outflow of sewage is impossible naturally. In both cases, to ensure the operation of the sewerage system, it is required to install a fecal pump in the well.

Preparatory work

To install the fecal, a receiving well of 50x50x50 cm size is needed. The optimum capacity of the well should be no less than the average daily discharge volume, taking into account the number of people living in the house, but not more than 5 meters in depth.

If the installation of a fecal pump at a dacha or private house is provided in the soil, then the walls and the floor should be concreted and provide a reliable waterproofing. To avoid unpleasant odors, the top cover must also be made sealed.

As a receiving well, it is very convenient to use a plastic container installed deep in the ground and ensuring the inflow of sewage naturally. Installation of the fecal pump in the well should proceed as follows: in the upper part of the well, there must be an inlet pipeline that will provide a filling of at least 40 cm. The outlet pipeline must be withdrawn to the top of the well or wall, everything depends on the location of the sewer or septic tank . The diameter of the outlet piping should not be less than the outlet of the pump set.

If the distance to the central sewerage or septic tank is too large and is at the limit of the possibilities of the equipment used, the pipeline should be laid as straight as possible, avoiding turns and bends or making them rounded and smooth.

Installation of a fecal pump by one's own hands

The installation of the fecal pump is simple and affordable. Any master, who has some skills in working with tools and mechanisms, is able to install a fecal pump for cesspools. And not only. Once the well is completed, a pump set should be installed on its bottom. The metal supports provided by the design will provide a minimum clearance between the intake port and the bottom of the well. For more reliable operation, the pump casing can be suspended on a sturdy torso or placed on a supporting structure.

Specialists do not recommend the use of a flexible hose as a discharge pipe - this can lead to clogging during prolonged use. The most optimal option will be a PVC pipe with a diameter of 63 or 75 mm, pumped to the pump equipment without sealing the connections.

To prevent backfilling of the liquid, after the device is disconnected, the non-return valve cuts into the pipeline. The possibility of preservation of the sewage system is provided by a shut-off valve, which is mounted in the pipeline behind the check valve. With a long-term absence in the owner's house, the valve closes, which allows cutting off the faecal pump for cesspools from external sewage. The discharge pipeline must be carefully insulated to ensure reliable operation in winter.

Electrical connection

The pump unit is connected via an electrical panel, which must be equipped with all necessary protective devices. For example, an automatic circuit breaker monitoring the occurrence of a leakage current and a short-circuit current, as well as grounding, control panel and protection to forcibly turn off and on the pump, if necessary.

To ensure the normal operation of the sewage system in case of emergency power outage, it is recommended to purchase a diesel or gasoline generator of the appropriate capacity.

Commissioning works

When a faecal pump with a chopper (or without a chopper) is fully installed, power is connected, a piping system is installed, a test of the equipment should be carried out and the level of operation of the float switch should be set.

The tank is filled with clean water, to begin with, the level should be minimum, the cut-off point is determined by the float sensor. Further, the water is filled up to the level of the sensor that is required to start the pump.

Trial run allows you to determine the operability of the installed sewage system. If any malfunctions are found in the operation of the equipment, they can be safely eliminated at this stage. If the test passes without remarks, the receiving well should be hermetically sealed. From that moment the system can be used without any restrictions.
