Installation of the sewer pump

The layout of the location of bathrooms and plumbing devices in country houses and dachas is always associated with the difficulty that they must be placed close to the sewer riser. Also, the pipes leading to the riser must have a slope in his direction so that wastewater can move by gravity. Such conventions impose certain restrictions all plumbing should be located not far from each other. This problem becomes irrelevant if you install sewer pumps. The use of these pumps allows you to install a toilet, washing machine, shower and other devices where it is convenient for you, in the basement or basement below the location of the main sewer pipe. This is especially true for cafes, restaurants and sports clubs located in the basements of high -rise buildings. Sometimes fecal submersible pumps are placed in suburban houses, processing drains from all over the house and pumping into a septic tank. Such pumps differ from those described above, and in order not to make a mistake, you must understand what the pump is intended for.

Types of sewer pumps

Sewer pumps can be conditionally divided into two categories: household and industrial. Household pumps are designed to pump wastewater from one or more consumers and can be used in country houses, private small hotels, cafes, restaurants, bars, clubs and stores. Industrial sewer pumps are installed in multi -storey buildings or even at substations leading to the sewer manifold.

Household sewer pumps

Sewer pumps for household needs differ in purpose and place where they are used, and also have structural differences. For example, there are pumps that are installed directly for the consumer of water, and there are pumps for forced sewage, which are installed in the bar of the septic tank or sewer pumping station.

Household sewer pumps are in this performance:

• Sewer pump for toilet (equipped with a chopper).

A pump of this type is installed directly behind the toilet no further than 40 cm and is a box of approximately like a toilet drain tank. The color of the pump body can be selected so that it corresponds to the color of the toilet and does not catch the eye. The unit is connected to the pipe that drops from the toilet. When draining the water in the toilet, it fills the pump, where metal lobes-sinter lugs grind fecal masses and toilet paper. Such a pump can not cope with more serious garbage, for example, a towel and a personal hygiene product.

After grinding garbage, wastewater is supplied through the pipeline to the sewer riser. Typically, similar toilet pumps can pump liquids up to 10 m in a height and up to 100 m in a horizontal plane. After the wastewater is directed to the sewer, the toilet water survey is again filled with water.

Pipe -allotting from the pump can have a diameter of 18 mm to 40 mm. This allows you to lay them without harm to the overall design of the room, for example, behind drywall or under the ceiling. Small pumps allow you to install toilets in any room, regardless of the location of the sewer riser, as well as below the location of the main sewage pipe. For example, it can be a basement, a basement, redevelopment in a typical apartment and transferring a bathroom to another place.

For such sewer pumps, the price depends on the manufacturer. For example, popular French pumps of the company Grundfos Sololift2 WC-1 and Sololift2 WC-3 They cost 350 cu and 450 cu respectively. These are reliable units for which a guarantee is issued. In addition, in the CIS countries a network of service centers is quite developed, which are engaged in the installation and repair of sewer pumps of this brand. The pumps of another French company SFA (direct competitor) are in approximately the same price range. Model SFA Sanibroyeur Silence It costs, for example, 350 cu Although they are a little cheaper, they have less power and pump to a lower height. And here is the pump of the Russian company Sabline Service called Unipump Sanivort 600it will cost only 200 cu

The maximum wastewater temperature, which can pump the sewer pump for the toilet, is in the range of +35 C +50 C. In more detail this is indicated in the instructions for a particular model. Also, many pumps have an additional input for draining from the washbasin, shower or bidet, pussuar. Therefore, the water temperature is of great importance. If the water temperature is much larger, the pump may fail, although some models have a protection that allows you to pump hot water for a short time (30 minutes), but not constantly.

In addition to the toilet pumps, which are about 30x45x16 cm, there are also built-in pumping pumps for suspended toilets. They have compact dimensions, the thickness does not exceed 12 cm, so it is convenient to hide them behind a plasterboard partition.

There are also models that combine the toilet and pump without a drain tank. Such a device is not cheap ( SFA Sanicompact 43 It costs 900,1000 cu), but it is convenient and takes up little space. The toilet is connected to the water supply network directly and has an additional exit for draining from the washbasin.

• Sewer pump for the kitchen (without a grinder).

Such pumps are also called sanitary, since they pump dirty water, but are not equipped with a chopper, which means that drained water should not contain extraneous objects. The sewer pumps for the kitchen have several input pipes, so you can connect the drain from the sink in the kitchen, bathroom, shower and washbasin to them. They are installed in a closet under a sink or any convenient place. Pay attention to the maximum wastewater temperature that such a pump can pump. For example, a model Sololift2 D-2 For a shower, bidet and shells, it is designed for water not higher than +50 C. This means that it is impossible to connect a dishwasher and washing machine to it. It is also important that the kitchen pumps are rapidly covered with a fat plaque from the inside and require timely cleaning.

• Sewer pump, designed for temperature above +75 from.

This category of sewer pumps must be distinguished separately. Such units can take hot wastewater from washing and dishwashers, as well as a bath and shower. For example, to the pump Grundfos Sololift2 C-3 You can connect the sink, dishwasher, bathroom and shower. The water temperature should not be higher than +75 C, a short -term pump withstands a temperature of +90 C. This French unit is about 400 420 cu Sewer pumps Wilo Drainlift TMP 32-0.5 EM and SFA Sanivite Silence Also designed for water with a temperature of +75 C and cost 350 400 cu.

• Submersible sewer pump.

Such pumps are also called fecal submersible pumps, and they are radically different from all described above. Submissive pumps are installed in a well or container, into which wastewater flows from the entire country house. In principle, this can be not only a country house, it can be a cafe, a restaurant, a club or another object that has an autonomous sewage system. Submersible fecal pump is equipped with a powerful engine and cutting mechanism, which is able to grind not only feces and toilet paper, but also tissue towels, rubber gloves, female hygiene products, terry towels and other large items. The only thing he can’t cope with is with stones and metal objects, the hit of which must be avoided.

After grinding extraneous inclusions, wastewater is pumped into a septic tank, where they are cleaned. Submissive sewer pumps are made by companies such as Grundfos, Wilo, KSB, Flygt, Homan and Gorman-Europe. The case of such a pump and the grinder are usually made of cast iron or stainless steel. The pump itself can be equipped with a float that signals that the wastewater level reached a mark, after which the pump should turn on on pumping. In the same way, the float also controls the unit.

For fecal sewer pumps, the price depends on the power of the unit. For example, a powerful pump Pedrollo MS 30/50+Remote Qes300 with a capacity of 2200 watts costs almost 1000 cu, its analogue is simpler with a capacity of only 750 watts Pedrollo MCM 10/50 It costs 350 cu The reputation and requests of the manufacturer also affect the price. For example, a fecal pump of Ukrainian production DNIPRO-Mit will cost only 60 70 cu, although it has a capacity of 2750 watts.

In addition to the above to household sewer pumps, one can attribute sending pumps And the pumps that are attached to dry. They are also popular KNS (sewer pumping stations), which are a finished container for wastewater, in which the fecal pump of the required power is already installed. When choosing a pump for your home, be sure to read the characteristics of the unit and recommendations for its use, or better consult a specialist.

Sewer pumps

Industrial sewer pumps are used in multi -storey buildings, remote facilities, cottage villages and at enterprises for pumping wastewater into urban or autonomous sewers. The same pumps are installed at pumping stations and wastewater treatment stations. Conditionally industrial pumps can be divided into such groups:

• Submersible sewer pump (fecal).

Submissive pumps are all the time in a state immersed in water. Since the unit is in an aggressive environment, its case and parts are completely made in accordance with the requirements for stability. The popularity of such types of pumps is due to the fact that they are used directly inside the sewer pump station and do not require a special place for accommodation, as well as an additional pipeline.

It is also worth clarifying that submersible pumps are suitable for dry installation, only in this case it is necessary to properly organize the supply of pipes and the back of the input pipe.

• Console sewer pump.

Similar pumps are installed openly in the basements of high -rise buildings, as well as in sewer pumping stations of industrial level. Their main difference is that the pump and engine are located separately and are connected by a coupling. With proper operation, console pumps can serve for a long time without repair and breakdowns. In the event of the need to repair, it is easy to carry out, since the pump is in sight.

• Self -consuming sewer pump pump.

Such pumps are installed in a separate room on a specially equipped place inside the KNS (sewage pumping station). They have excellent characteristics, are convenient to maintain, but quite expensive, so they are rarely used at present.

When choosing an industrial sewer pump, it is extremely important to choose a model of such a manufacturer that can provide specialists for installation, and then engage in accompanying diagnostics, maintenance and repair.

Installation of the sewer pump

So, if there is a problem of the impossibility of promoting wastewater by gravity, then there is nothing left to remain how to install sewer pumps. We have already examined that the scope of their application is diverse and it is necessary to choose a specific model for specific tasks.

Connection of the sewer pump to the toilet

In order to be able to install the toilet in a place convenient for you, without tied to the location of the sewer riser, it is necessary to equip it with a sewer pump for the toilet. This applies not only to country houses, but also to the apartments in which the redevelopment is made, as well as the premises in the basement.

What pumps can be used to connect to the toilet? Grundfos pumps of model Sololift2 WC-1, Sololift2 WC-3, Sololift2 CWC-3 (installation in the wall), company pump Wilo Drainlift KH 32-0.4 EMSFA pump pumps SFA Sanitop Silence, SFA Sanibroyeur Silence, SFA Sanipro XR Silence and others. These sewer pumps received the most flattering reviews. They are characterized as reliable and high -quality units.

Most toilet pumps have additional input pipesto which you can connect drain from the washbasin, soul, bidet and pussuar. Therefore, with the help of one pump, it is possible to ensure the removal of wastewater from a whole bathroom.

The easiest way to connect the sewer pump to the toilet is the installation of a toilet with a built -in pump. How to do it, you can watch in a video example.

A conventional sewer pump is installed behind the toilet no further than 40 cm from it.

Tips for connecting the sewer pump to the toilet:

• Pay attention to the diameter of the input pipe on the pump. It must correspond to the output pipe of the drain sewer pipe from the toilet (toilet). If the diameter of these holes differs, then the installation will be wrong.
• Before installing the sewer pump, carefully read the instructions. Most often, it is equipped with all the necessary schemes and recommendations, and the pump itself includes everything necessary, up to the screws of fastening.

• First of all, it is necessary to insert connecting knees or supply pipes into the input pipes.
• Then install the pump behind the toilet and fix it to the floor using screws. On the pump body there are special cast ears with holes for such fastening.
• All pipes supplying to the pump should be located with a slope of 3 cm per 1 m, ensuring the promotion of wastewater by gravity.

• Then, a drop -out sewer pipe is connected to the output. What are the recommendations for its location, indicated on the photo example (the dependence of the pressure on the height and length of the pipeline).

• If the model of the sewer pump involves ventilation, then it is necessary to remove the ventilation duct above the skate of the roof of the house. Although there are models with a coal filter that provide the absence of unpleasant odors in the house.
• The pump is connected to the power supply through an assault rifle by 30 mA. If the pump model is supplied with a finished fork, then it can be connected to a personal outlet, the cable to which should be carried out directly from the shield and RCD.
• All bends of the removal and supply pipes should be smooth.
• All compounds of pipelines must be carried out with soldering, welding or adhesive compounds.
• If there is a need to take the wastewater in a vertical plane, then the vertical section of the outlet pipe must be made no further than 30 cm from the exit from the pump. This will provide normal pressure in the pipeline.

Please note that the toilet sewer pump can not be installed below the floor level and in the pits. Only next to the toilet, providing free access to the pump for maintenance and repair. So that the water that the pump takes could not return back, on the output pipe it is necessary to install the check valve.

Connection of the sewer pump in the kitchen

If it is planned in the kitchen install a dishwasher or washing machine, then the sewer pump must be selected resistant to high temperatures up to +90 C. The following models are suitable: Grundfos Sololift2 C-3, Wilo Drainlift TMP 32-0.5 EM and SFA Sanivite Silence. There are also more powerful models with a storage tank that can pump large volumes of wastewater from all devices in the kitchen.

You can install the sewer pump in the kitchen anywhere in the closet under the sink, near the wall, in the closet or other convenient place. The main thing is to calculate everything so that all the supply pipes are located with a sufficient slope (3 cm per 1 m) and have no length. Otherwise, you will have to use several pumps.

Tips for connecting a sewer pump for the kitchen:

• If several pressure sewage pumps are used, then they should have individual entrances to the common riser or highway. The connection of pipes that allotes from the pumps into one is prohibited.
• If the pipe that removes from the pump has an extended horizontal section, which is located below the pump level, then at the very top point it is necessary to set the valve (0.7 bar), which provides air access after the pump is turned off.
• If the pump model requires the equipment to cool the electrical circuit by air, then a special plastic tube will be included with the pump, which must be brought into a special hole in the housing and removed vertically 50,80 cm above the pump. This will provide an air flow for cooling electric circuits.

The pipe that removes from the pump should be made of solid plastic, for example, polypropylene or polyethylene. A flexible corrugation in the pressure sewer cannot be used.

Installation of the sewer pump in the prefabricated well

For processing and pumping wastewater, a fecal pump is used in a septic tank. In cases where the flow of wastewater from the house is impossible to a septic tank, for example, if it is far away, a prefabricated well is equipped next to the house, into which the sewer pump is installed. Pastes flow out from all over the house to the assembly well, here the pump grinds them and pumps them further into the septic tank for cleansing.

Also, the installation of a prefabricated well is possible if the central sewage system is at the distance and it is necessary to create a pressure that can direct wastewater straight into it.

The most convenient option for buying and installing KNS (Sewage pumping station). It is a plastic capacity of various volumes and shapes, the material of which is resistant to aggressive environments. The container is completely tight and there is practically no danger of leaks. A fecal pump is installed inside the container, which processes garbage and wastewater and pumps them further. Most often, such pumps are submersible.

Under the container, you need to dig a pit of the required depth. Only the hatch should remain above. The bottom of the pit should be tamped, and then equip a concrete pillow on top. To do this, pouring crushed stone, sand is performed, and then concrete is poured with a layer of 10 15 cm. After the concrete is hardened, in about a week you can install the sewer station. It must be lowered carefully. The KNS should be strictly vertically.

The connection of the pump is carried out strictly according to the instructions. For this, a cable and a chain are provided for lowering and lifting the pump. The diverting pipeline should be made efficiently using soldering or welding.

Then the CNS capacity must be filled with water, this will make it possible to sprinkle around the container. As the container fills with water, from the outside the KNS wall you can pour sand to the very top. The last 15 20 cm can be laid sod. After fixing the KNS in the pit, the water can be launched.

The installation of the sewer pump with your own hands is not difficult, but only if you strictly follow the instructions and do not compromise. For example, it is impossible to install a toilet sewer pump in a prefabricated well or a pump with a temperature limit of +35 C to connect to a washing machine. Dressed instructions are provided directly to connect the pump. If suddenly you cannot understand it yourself, do not risk it, seek help from professionals.
