Domestic suburban areas in the vast majority are not connected to a centralized sewer. In many villages and horticultural partnerships, it is simply not provided. And sewage sewage and flood waters need to be pumped out somewhere anyway.
Therefore, your own fecal pump to give just does not hurt. Find out which model is better to choose, because the range of sewage pumps is extensive.
In order not to be mistaken with the purchase, it is necessary to compare the characteristic features of different pumps with the upcoming conditions of operation, as well as to assess the feasibility of acquiring in-house sewage installation. A small review of the best manufacturers will help you choose a reliable unit for the garden.

Why at the cottage need a fecal pump?
Choose a model fecal pump should be based on specific needs. There is no large amount of sewage in the country. The owners of the city come only in summer and often only on weekends.
Most of them install an outdoor toilet or a cesspit on their summer cottage, which is quite enough for the disposal of the resulting sewage.

The fecal pump is designed for periodic pumping of the full 2/3 cesspool and storage tank.
In the complete set of pump presented for sale, there is an electric cable in a waterproofing sheath, a float switch and a sleeve that is hermetically connected in the equipment branch pipe
In the summer cottages, sewage pumps are rarely installed permanently with rigid pipes connected to the system.
In most cases, the fecal pump is immersed in a cesspool, concrete or plastic tank, and upon completion of pumping, it is removed and washed
The float device responds to changes in the level of the pumped medium. When lowering it to the limit value, the float turns off the pump so that it does not work "idle"
In front of the suction device, a shredder is installed on the bottom of the faecal pump, splitting large organic inclusions into particles suitable for pumping
Pumps for sewage maintenance are selected for power, permissible contamination, feed height and other data that can be found in the technical passport and on the instrument nameplate
If the dacha is equipped with an internal sewage system that needs to stimulate the movement of drains, a fecal sewage station is installed. This device is also equipped with a grinder.

Domestic sewage equipment
Fecal (sewage) pumps in the country are used for pumping and pumping out of liquid media:
- contaminated organic and fibrous inclusions drainage effluents;
- flood water from the basement;
- sewage from cesspools and septic tanks;
- muddy sediments from sewer and drainage systems;
- clean water for watering the garden;
- emptying the well during its cleaning.
The use of pumping equipment in the country is huge. With the right choice of the model, it will be possible to solve most of the problems that arise when pumping (pumping) the water masses in the farm.
The range of fecal pumps is huge. Before going to the store does not hurt to understand all the nuances of different types and thoughtfully assess their needs in terms of future use of this unit
If you choose a pump with errors, you can only use it to solve a single problem. And the rest of the time she will lie in the garage, taking up space and constantly interfering.
Often, fecal pump is also used for the organization in the country forced sewer system. Standard sewage is usually designed taking into account the free flow of drains from the country house to the septic tank.
However, it is not always possible to organize such a scheme. Due to the relief of the VOC site or input into the centralized system of sewage in the village, it may be located above the exit from the house.
Pipes to lay at the desired angle is impossible. And then for the forced pumping of gray and black water from the internal sewage system, it is necessary to install a suction pump.
The variant with redevelopment and rebuilding of the country house is also possible, when the configuration of the pipelines changes inside the residential building. But in most cases at the dacha a fecal pump is used. for pumping cesspools, septic tanks and melt water from the basement.
Types of sewage pumps
Fecal pumps are divided into indoor and outdoor installations. The first models are chosen for installation near toilet bowls and sinks. They are intended for forced pumping of sewage through sewage pipes to a septic tank.
Such units can be designed to connect one or several plumbing devices. The second category of sewage pumps is more familiar and it is they who are most often bought for summer cottages.
Depending on the design features and installation method, all models of faecal hydraulic pumps are divided into three groups: surface, submersible and semi-submersible.
It should be clearly separated fecal, for drinking water and drainage pump. The former were originally designed for grinding solid feces and small debris.
The second and third are designed for pumping water, only pure or having fine fractional suspensions. If a rag or food residue gets into them, these electropumps will simply break.
Group # 1: surface aggregates
Surface fecal pumps provide for a dry installation method. To work in automatic mode, they are mounted near the cumulative collector or in manhole. In fact, it is a small pumping station of several separate parts.
At the cottage surface pump for dirty water is used most often in a portable version, it is collected and included as needed, and then removed back into the utility room
This type of hydraulic pumps for sewage is the easiest to maintain and operate. He himself at the dacha is installed next to the cesspool or drain pit, and the hose connected to it sinks into fecal matter.
When choosing this pump, special attention should be paid to the maximum possible suction depth. In the passport usually indicate 8-10 meters. If the pit is deeper, then this pump will not be able to raise drains from it.
But here it is necessary to take into account not only the size of the tank from which water is pumped out, but also the distance from it to the pumping equipment. Each horizontal meter of hose reduces the depth of the unit by 10 cm.
Low-power models are a compact unit and for short-term work are installed on the floor or the ground next to the waste tank.
More powerful installations require a stable platform. They are mainly mounted in a room where such a platform can be safely and securely fixed on the floor.
The main disadvantage of a surface sewage pump is the inadmissibility of its operation in a wet environment. Only a retractable hose may be in the water; the housing of the unit must be on the ground and in a dry place.
It is allowed to operate such a pump only not in rainy weather, but rather to build a small carport for it altogether, otherwise moisture will get inside the case, which will inevitably lead to a short circuit.
Surface models are cheap and easy to maintain, but quite noisy. If the pump is selected for installation in the back room or basement, then this is the best option. But for working on the street and pumping feces from a septic tank, which is far from a country house and buildings, it is better to purchase an immersion counterpart.
Group # 2: semi-submersible kits
Pumping equipment of a semi-submersible type consists of an electric motor installed in a dry place and a working chamber immersed in drains. Together, they are connected by a rotating shaft.
In country houses and in general in domestic conditions semi-submersible pumps are rarely found, they are structurally complex and in terms of operation - they are mainly chosen for industrial-level pumping stations.
If a semi-submersible hydraulic pump is purchased for the dacha, then it can be mounted by:
- mounting on the wall of the drain hole;
- installation on a floating platform;
- installation in the extension next to the drive.
Another potential problem with a semi-submersible model is the lack of a standard grinder kit. And without it, the pump when pumping debris and faeces from the sewer system will quickly fail.
The grinder on similar installation is installed in addition, in the form of a nozzle. And this is an increase in the cost of equipment and the complication of its maintenance.
Group # 3: submersible hydraulic pumps
This modification of suburban fecal pumps involves the direct immersion of the entire unit in a pit with sewage. And so that the installation does not break in an aggressive and active environment of sewage, its hermetic case and all working parts are made of cast iron or stainless steel.
There are models with a plastic casing on sale, but it will not last long in sewage drains. Submersible equipment for pumping feces can be used both for one-time work and in automatic mode.
In the second case, the sewage pump for giving should be selected with a float and automatic. When a specified level of liquid in the waste tank is reached, the pumping equipment is first turned on, and then, as the wastewater is pumped out, it is turned off by a float device.
The installation of a submersible fecal pump is carried out directly to the bottom of the drain pit or is suspended at a height of 10–20 cm above it (+)
The presence of the float eliminates the work of pumping equipment “dry”, which significantly prolongs its life. Submersible pumps are selected for those who require efficient and reliable equipment.
Many of these models are equipped with a built-in grinder. He stands at the input and grinds all incoming waste to a state in which it simply can’t break the internal mechanisms.
Compared to the surface competitor, a submersible pump is less noisy and consumes less electricity. All its power goes into maintaining pressure in the discharge pipe. He does not have to waste energy on sucking sewage from the bottom into the working chamber through a hose.
During operation of the submersible installation, water absorbs most of the noise generated by the electric motor. But the unit is more complicated to operate and costs more than a surface model of similar capacity. Equipment, which is immersed in sewage drains, is initially more technological and sophisticated than the equipment remaining in the air.
Intra house sewer installations
Fecal pumps are also called small pumping stations, which are designed to be embedded directly into the sewage system inside the country house. Constructively and on the principle of operation, such pumps resemble counterparts from washing machines.
First, drains in such a household installation accumulate in a small tank, and as it is filled, they are pumped out by an internal submersible pump into the sewer pipe (+)
Such models of faecal pumps belong to the premium segment of plumbing and cost a lot. However, thanks to them, toilets, showers and washbasins can be installed almost anywhere in a residential building. They calmly pump sewage even through pipelines tilted upwards.
The design of this pumping station was originally incorporated the principle of self-cleaning. It is undemanding in terms of maintenance, it is enough only occasionally to flush the tank from the silt.
It also has a carbon filter and a check valve. The first excludes the emergence of an amber in the sewer, and the second does not allow the return of sewage from the sewer back to the drive. Fecal toilet pumps prevent blockages and provide forced drainage.
How should I choose a fecal pump?
Passport sewage pump for giving contains a lot of technical characteristics. And all of them must be considered when choosing this technique. The first indicator is the operating temperature of the pump, i.e. drainage temperature.
Pumping equipment for sewage can be:
- Designed to work only with cold and warm water up to + 45 ° C.
- Designed for pumping waste with a temperature of up to + 90 ° C.
For pumping water from the cellar and fecal impurities from a street septic tank, a pump of the first category is sufficient. But for the smooth functioning of the forced sewers with a lot of plumbing in a country house will have to select a model from the second group.
Automation, chopper and body material
Constantly monitoring the state of the fecal pump and managing its operation manually means that it is wasteful to spend your time. At the cottage is always full of classes. Therefore, the equipment should be immediately selected with a float and thermal relay.
The first will control the level of drains in the pumped well, turning off / on the pump if necessary, and the second will prevent overheating of the electric motor.
Some faecal pumps are able to cope with solid waste and pebbles without a shredder, but only the presence of a cutting mechanism guarantees such a technique a long service life.
Structurally the grinder is carried out in the form:
- two-blade knife;
- impeller with cutting edge;
- combined mechanism with multiple blades.
The impeller is the cheapest option of a grinder, but the performance of the pumps with it is the lowest. A knife with a pair of blades perpendicular to each other is more reliable and productive.
However, the most advanced is the combination of three cutting blades and a perforated disc. Passing through a similar shredder, solid faecal fractions turn into a homogeneous milled mass.
Additional selection tips and best chopper chopper pump options are presented in this article.
According to the material of the housing, the pump for pumping sewage at the dacha is best to choose from metal. Stainless steel and cast iron will last many times longer than plastic. Especially this nuance is important for submersible technology, which is constantly in the aggressive composition of dirty waters.
Lift height, power and power supply
The higher the performance indicated in the passport, the faster the pump will pump the drains. However, the more it consumes electricity. A rake at a dacha is rarely large when done, so a low-capacity unit is often enough to work in the summer cottage. He will pump out the drains not in 5 minutes, but in 20, but there is nowhere to rush in the country.
The best for giving option of the pump on power - 400–500 W. This performance is in the region of 140–160 l / min. Such performance characteristics will make it easy to cope with the pumping of sewage from the drain or cesspool, and getting rid of excess water in the dacha cellar.
The head figures show the maximum height to which the pumping equipment along the pressure pipe is able to lift the fluid with feces. But when calculating this indicator, one must take into account not only the vertical section of the highway, but also the horizontal one.
In addition, atmospheric pressure, the material of manufacture and the cross section of the pipes, as well as the temperature of the effluent and the size of impurities in them should be taken into account.
In a simplified calculation of the desired head, the footage of the horizontal section is divided by ten and added to the length vertical section of the pipe, and then it all increases by 20–25% - the resulting figure should be less than specified in data sheet (+)
Some models of sewage pumps are powered by a single-phase network, while others are powered by a three-phase one. The first group is cheaper. As a rule, for giving it is recommended to choose such a fecal pump. It will cause less problems with connecting to the mains. And if necessary, it can be powered from a portable generator.
With choosing a fecal pump preference is better to give models of well-known manufacturers. They specialize in such equipment, so their equipment is always on top. Even with breakdowns, parts for repairing such pumps are always much easier to find.
Among the variety of brands for use in the country fit:
- Pedrollo vortex - a series of "VXm" with a small capacity (Italy).
- Jilex - “Fecal” series (Russia).
- SFA - compact pumps grinders for the house (France).
- Grundfos (Denmark).
- Marina-speroni (Italy).
- Calpeda (Italy).
- Vortex (Russia).
- Belamos (Russia).
It is worth saying that Russian pumps are in no way inferior to imported counterparts. They were originally developed for domestic realities with voltage drops, etc.

Overview of the submersible pump with grinder:
While living in a country house outside the city, most of us do not want to give up the benefits of civilization in the form of a shower stall, toilet bowl and other sanitary ware. But all this can be used only if there is a septic tank or cesspool at the dacha.
However, if there is no fecal electropump on the farm to clean them, then the constant calls of the recovery truck will cost a considerable amount. In this case, your own pump can be used not only for pumping sewage, but also for watering and getting rid of melt water in the basement in the spring.
