Installation of a fecal pump for pumping sewerage by one's own hands
Waste management is a delicate, but veryan 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 stoppers and blockages, 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 sewageequipment of this type. It is taken into account the absence or presence of a grinding mechanism, the type of construction, the temperature of the pumped-out effluent and the method of installation.
Equipment for cold drains without a chopper
Fecal sewage pump designedfor pumping cold currents, without a chopper, in comparison with 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
Fecal pump for sewage, whichIt is designed for pumping hot runoff, without a grinding mechanism, it is able to pump liquid without solid particles with a temperature of 90 ° C. Such drains are characteristic for baths and saunas.
A device for cold drains with a shredder
Pump for pumping cold domestic waste water withChopper 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 (wadded disks, tampons, etc.) easily break up into small particles using a cutting mechanism, and then, together with contaminated water, are pumped out. Pumping equipment is designed for a temperature of not more than 40 ° C.
Pump for hot run-off with shredder
Device for pumping hot runoff withthe 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 best 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 withshredder 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
Fecal pump for pumping seweragefunctions 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 considerable variation in power: a fecal pump can be installed in the country 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 up to 400 m3 in a minute.
Due to the immersion method and the large mass,pumping equipment is fixed on a special steel cable - like well 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 high.
Semi-submersible
A distinctive feature of this device isa special 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 that this fecal pump has for pumping sewage is the absence of knives, but it pumps up inclusions up to 15 mm in diameter.
Semi-submergible aggregates are quite highcapacity 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 is in itsconnection to plumbing systems, in the working environment, he is in "free navigation". 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 the feces and liquids form the basis of the 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 -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 the 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 not 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 the fecal pump can be itselfdiverse. Simpler models are installed by consumers in accordance with the recommendations specified in the manual, and installation of non-standard and complex devices should preferably be entrusted to specialists.
Fixed installation
Pumping equipment of this type is operatedin the stationary mode, if it is required to pump sewage into a septic tank located in accordance with sanitary norms, at a distance of not less than 15 meters from a residential house, from a water well - not less than 50 meters.
Another application of the pump isthe need for forced pumping out drains into the main sewage system, when the system is located above the level of the house, and outflow of sewage is impossible naturally. In both cases, to ensure the operation of the sewage system requires the installation of a fecal pump in the well.
Preparatory work
To install the fecal a receivingwell 50x50x50 cm. 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 orThe private house is provided in the ground, 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 convenientUse a plastic container installed deep in the ground and ensure the inflow of sewage naturally. The installation of a fecal pump in the well should proceed as follows: in the upper part of the well there should be an inlet pipeline that will ensure a filling of at least 40 cm. The outlet pipeline must be withdrawn to the upper part 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 orThe septic tank is too big 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
Installation of the fecal pump is simple andavailability. 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.
Experts do not recommend as a tapuse a flexible hose - 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 avoid reverse fluid overflow, afterDisconnection of the device in the pipeline cuts the non-return valve. The possibility of conservation 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 is closed, which allows cutting off the faecal pump for cesspools from external wastewater. The branch pipe must be carefully insulated to ensure reliable operation in winter.
Electrical connection
The pump unit is connectedthrough the 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 normal operationsewage system in case of an emergency power failure, it is recommended to purchase a diesel or gasoline generator of the appropriate capacity.
Commissioning works
When installing a faecal pump with a chopper(or without a shredder) is completely completed, 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 container is filled with clean water, to startthe level must be minimum, the cut-off point is determined by the float sensor. Further, the filling with water occurs up to the sensor response level required to start the pump.
Trial start allows you to defineserviceability 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.
