Features and application of forced sewerage

Manufacturers and models

Not many companies produce individual sewer installations. However, the price range is quite wide. Traditionally, European manufacturers are distinguished by good quality, but high prices. No one will be surprised if we say that Chinese sewage pumps cost less, but their quality is worse. In general, the choice, as usual, is expensive and high quality, or cheaper and…

Forced sewage installations Grundfos (Grundfos) - Sololift (Sololift)

The well-known plumbing manufacturer Grundfos (Grundfos) produces pumps for forced sewerage Sololift (Sololift). At the moment, a modified Sololift2 line has been launched. It has no moving parts in contact with drains. The exception is the chopper, but its drive is also “dry”. This makes the renovation less of a hassle. There are several Sololift models for different occasions:

Sololift sewer pumps are not the cheapest equipment, but they work reliably and correspond to the declared characteristics. The firm also supports warranty repairs.

Pumps for toilets, bathrooms, kitchens and technical rooms SFA

This company specializes in the production of sanitary pumps. There are several lines for solving different problems, connecting various devices:

SFA products work reliably and cost a little less than Grundfus. You can choose a model for any combination of plumbing. In general, the SFA sewage pump is a good option. Installation of equipment is standard - put in any convenient place. There is only one limitation - it is better that the branch pipeline starts from a vertical section, if there is one on your route. If this is not possible, the length of the horizontal section should be no more than 30 cm.

The height of the vertical section is calculated taking into account the fact that the horizontal one must have a slope towards the inlet of at least 1% (1 cm per 1 meter of pipe).

Aquatik CompactLift fecal pumps

Toilet pumps Compact Elevator is manufactured by the Chinese company Aquatik. This is a more budget option for individual sewer installations. Differ in low level of noise.

At the moment there are only three modifications:

Aquatik guarantees its bathroom and toilet pumps for 1 year from the date of sale. Violation of operation (the presence of fibrous inclusions in drains) may cause a denial of warranty repairs.

Willo sewage pumps

The German company Willo is known for making reliable devices. Toilet pumps are no exception. Good quality plastic, thick tank walls, reliable pump. There are the following models:

The range of Willo sewage pumping units allows you to solve any problem when it comes to equipping bathrooms and toilets in private homes. For commercial or more intensive use, Willo has other solutions.

Pressure sewer pumps STP (Jemix)

These customized sewer units are made in China. The price category is average. Reviews, as usual, are different - someone is completely satisfied, someone absolutely does not like it.

So, here are the sewer pumps Jemix offers:

It differs from those described above by increased power - some models raise drains by 9 meters. Most of the sewer pressure pumps described above can lift drains up to 4-5 meters. So this is where the Jamixes win. In this parameter, they have only one competitor - Sololift Grundfos with its lifting height of 8 meters. But his price category is completely different (as is the quality, however).

Device and purpose

A pump with a grinder is a surface sewer pumping unit that allows you to organize the removal of wastewater where it is not possible to do this using a gravity system. This is a small plastic container with a powerful built-in pump that pumps wastewater into the sewer. Drainage can be moved both vertically and horizontally. There are installations with a grinder that can be connected to toilets, there are without a grinder - for "gray" drains from sinks, showers, bidets, etc.

Application area

A sewer pump is used in cases where it is impossible to make a gravity sewer system. In most cases, when a plumbing fixture, washing machine or dishwasher is installed below the sewer inlet. For this, forced sewage pumps were invented. This solution allows you to transfer bathrooms and technical rooms to the basement or semi-basement.

Another pump with a chopper is installed if it is decided to make the bathroom after the repair is completed and the sewerage system has not been connected to the place of the proposed installation of plumbing. In this case, the installed equipment is connected to a compact sewer pump, and it is connected to the sewer. What's the Difference? In the following:

• the diameter of the outlet pipes for the sewer pump is much smaller than for the gravity system (28-40 mm);
• drains can rise up to a height of up to 9 meters;
• horizontal sewage disposal is possible up to 100 meters (requires a minimum slope of 1-4%).

All this allows you to organize a connection to an existing sewerage almost anywhere at minimal cost.

Device and principle of operation

The sewer pump consists of a storage plastic container and a pump. Some models that can be connected to the toilet have a chopper. The filling level is monitored by a sensor. When it works, the chopper and pump turn on, the waste is pumped into the sewer system. Shutdown controls the second sensor - it turns off the power when the level of drains falls below a certain level. This is a simplified algorithm for the action of a pressure sewer.

There are sewer pumping stations designed to connect devices of various types and quantities. The simplest one is designed to connect one or two devices, the most productive one has three additional pipes (and one main one). Accordingly, the container has one or more inlets (depending on the model) and one outlet. Pipes coming from plumbing are connected to the inlets, and the outlet is connected to the sewer.

For pumping out high-temperature effluents from washing machines, dishwashers, bathrooms, there are special models made of heat-resistant materials. A conventional sewer pump cannot cope with such a load. Therefore, to connect such equipment, you need to look for certain models.

The use of forced sewage

Features of drainage of dishwashers and washing machines

Everyone knows that modern automatic machines (washing machines or dishwashers) must be connected to the sewer in order to divert contaminated used water. But in small city apartments there is hardly any place to install these assistants in the place where the sewer passes, this is typical for both the bathroom and the kitchen.

Yes, and in large cottages, you want to hide the units in the basement, which often serve as the utility floor. In both cases, there is a solution if forced sewage pumps are used. The gist of the solution is as follows:

• It will require the placement of a special sewer installation equipped with a water collection tank and a built-in pump.
• Drains gradually fill the container in which the float switch operates.When their volume reaches a certain value, the pump turns on, pumping polluted water into the sewer.
• Such a forced sewage system is small in size and is installed in an apartment or house in close proximity to the equipment that produces drains.
• It is equipped with a charcoal filter that prevents unpleasant sewage odors from entering the room.

Reliable and efficient system does not require specific maintenance measures, it is only necessary to periodically clean and flush the tank.

Reconstruction or relocation of the bathroom

As mentioned above, the transfer of the bathroom to another, more convenient place can be done in two ways:

1. carry out redevelopment of the apartment, having carried out a major overhaul of the premises;
2. install forced sewage pumps.

The second option is more affordable and faster. But at the same time, you need to purchase a sanitary pump that meets special requirements. After all, he will have to work with aggressive environments.

Types of forced fecal pumps

• Equipment for pumping gray wastewater at high temperatures without including fecal waste
  . In this case, the pump does not have a chopper and is able to transport hot, more or less clean water from a washing machine or dishwasher, as well as from a kitchen sink. The dimensions of the installation are quite compact, which allows you to mount the sololift directly in the kitchen cabinet under the sink or even on the wall. The pump works with water, the temperature of which does not exceed 90 degrees. Such equipment is relevant for installation if the kitchen or laundry room is far from the central riser.
• Model of the pump for hot drains with a chopper
  . This device is designed for pumping wastewater, the temperature of which can reach 95 degrees. Thanks to a powerful knife built into the mechanism, the sololift recycles all fecal and hygienic waste, including small items. Thus, the installation of such a forced sewage system is relevant in almost any of the plumbing or utility rooms of a private house or apartment. But the cost of such a sololift is several times higher than that of the previous model.
• Pump with chopper for cold drains in the house
  . Most often, this particular unit is used for installation behind the toilet. The sharp chopper blades are great for any fecal debris. Thus, the equipment can work uninterrupted, provided that the temperature of the drains does not exceed 40 degrees. Included with such a pump is a special coupling for high-quality connection of the forced sewage system with the toilet.

The device and principle of operation of forced sewage

To understand how the effluent enforcement system works, you need to know its structure. So, the forced sewage system consists of a capacious reservoir, inside of which are located:

• Special attachment-chopper;
• Carbon filter;
• float switch;
• Pump unit.

Sololift works like this:

• Drains enter the storage tank until they fill it up to a certain mark;
• At this moment, the float switch gives a signal to the pump, and it starts its work;
• The chopper is also turned on here, which turns the drains into a mushy liquid;
• The pump pushes the recycled water into the collector and further into the central drain.

Sololift installation

When buying a forced sewer system, pay attention to the fact that different sololifts are designed for different plumbing fixtures. Manufacturers produce them separately for:

Manufacturers produce them separately for:

1. toilet bowl
2. shells;
3. baths;
4. shower cabin.

Pro tip:

The diameter of the inlet of the sololift must correspond to the diameter of the outlet of the drain sewer pipe.Otherwise, the installation will be incorrect.

Installation of forced sewage can be done by hand, calling for the help of specialists only to connect it to the mains. Forced drain is installed according to the instructions.

The best option is considered to be such an arrangement of the pipeline, in which its beginning has a strictly vertical position, and then it runs horizontally, with a certain slope. The main parameters for horizontal and vertical sections of the pipeline, as well as the slope value, are prescribed in the technical passport of the sololift or in the installation instructions.

The figure clearly shows the inverse relationship between the length of the vertical riser and the dimensions of the horizontal one. If the vertical section of the pipeline rises to a height of no more than 1 m, then the length of the horizontal pipe can be 50 m. But if the height of the pipeline is 4 m, it cannot exceed 10 m in horizontal length.

As an example, we present a fragment of an instruction for forced sewage:

Insert the drain pipe from the toilet bowl or siphon into the intake device.
Bring the opposite part of the sololift to the sewer riser.
Connect the sololift to the electrical network through a socket or directly into the shield

It is important that the system is provided with a residual current device (RCD).

Thus, it is quite simple to carry out self-assembly if you have at least minor skills. In other cases, it is better to entrust it to specialists. Otherwise, forced sewage systems have practically no restrictions in use and will be an excellent assistant in the redevelopment of housing.

Sometimes it happens that in the purchased apartment, the sanitary and utility rooms are not located quite the way the new owner would like in accordance with an interesting interior idea. Or maybe just in a private house there is a need to re-equip the collector in order to deliver several new household appliances. In these and other cases, the problem of draining into the central riser may arise. Forced sewerage (sololift) will help to resolve the issue without the maximum expenditure of finances, time and effort.

Such a device is a powerful fecal pump with a built-in mechanism for grinding fecal debris and its further transportation through sewer pipes.

It is important to use such a forced pump in such cases:

• Redevelopment of an apartment or a private house with a change in the location of the kitchen or utility room (laundry room);
• The need to install household appliances that work with water in a house or apartment in non-standard places;
• Installation and arrangement of a laundry room or a bathroom in the basement, where the sewer pipeline will pass below the level of the central drain;
• Forced transportation of wastewater from a prefabricated well of a private house to a septic tank, provided that the pipeline is too long.

• So, with the use of such a device, it is possible to avoid complex, dirty and costly repairs for the redevelopment of the building;
• Compactness of the device
  allows you to install it directly behind or under a plumbing fixture, hiding from prying eyes and without disturbing the picture of the interior;
• Sololift power
  allows you to raise drains into the drain to a height of 5 to 7 meters, and transport them to the storage tank at a distance of up to 100 meters horizontally.
• Performance and quality of the grinding mechanism
  allows you to turn fecal effluents containing garbage into water of a mushy consistency, which makes it possible to transport it to the drain through pipes of small diameter (18-40 mm);
• Convenient location of sewer pipes in the room
  due to the small cross section;
• The presence of a special carbon filter in the installation
  , which prevents unpleasant sewer odors from entering the room;
• Relatively low installation noise
  , which makes the use of the sololift as comfortable as possible for all household members.

Sewage pumps Sololift Grundfos models and their characteristics

The most popular units used for forced discharge of wastewater into the sewer are pumps. Grundfos
. The entire line includes five models, each of which has its own technical features.

• This model is not equipped with a cutting mechanism, and therefore is intended for the disposal of wastewater that does not contain solid fractions. Can be connected to a shower, washbasin, bathtub or bidet. The most compact and economical model
  from the entire Grundfos Sololift range.

• SOLOLIFT2 C-3

  This model also does not have a chopper, so it cannot be connected to the toilet. A distinctive feature of the Sololift2 C-3 is ability to withstand high temperatures
  , and therefore such a pump can be used to organize a forced sewage system in the kitchen - to divert drains from the kitchen sink and dishwasher.

SOLOLIFT2 WC-3
This model can also be integrated into a forced sewage system for toilets, as it has a built-in chopper. This pump differs from the previous model in that it has 3 inlet connections, and therefore it can be connected to several plumbing devices at the same time.

The typical location of the sewer riser in an apartment is often not the most convenient for its owners, because the location of the kitchen and bathroom depends on it, forced sewerage is a relief from this inconvenience. With its help, it is possible not only to organize the disposal of wastewater, bypassing the need for redevelopment (and the capital construction work associated with this), but also to install plumbing fixtures in the basement of a private house (when the plumbing is below the riser, and drains cannot be drained by gravity).How to create such a system, you can learn from this article.

How does this sewer work?

Forced sewage equipment is most often installed in country houses. Otherwise, the system is called sololift. The equipment for this type of sewage is a pump with a grinder, which has compact dimensions and is hidden in additional plumbing or in the toilet bowl.

Effluent entering the forced sewage device is pumped out and ground by a grinder. After that, sewage enters the septic tank or into the central sewer pipeline.

The pump with a chopper has high power parameters. This allows him to cope with a wide variety of human waste and divert them in any direction: in the vertical - by five to seven meters, in the horizontal - by a hundred meters. A vertical outlet is necessary if all plumbing is below the sewer.

For the removal of wastewater using forced sewage equipment, large diameter pipes are not required. The diameter of the pipeline can be from 18 to 40 millimeters. This allows you to install sololifts yourself.

Forced sewerage can be arranged almost anywhere in a private house, since there is no need to consider how: horizontally or vertically - the sewer riser will be located. In addition, with the help of such equipment, you can solve the age-old problem of the standard layout, which involves the location of the toilet next to the kitchen.

Principles of correct installation

• So, it is worth making sure that the cross section of the pump nozzles and pipes are the same. Otherwise, the installation of the equipment will be leaky.
• All bends and turns of the sewer should not have sharp corners.
• If it is planned to raise the drains vertically, then you need to mount the vertical pipeline with your own hands from the pump at a distance of no more than 30 cm.
• It is forbidden to mount a sololift in lowlands and depressions. Access to him should be free.
• If several devices are being installed in the house at the same time, then for each of them there must be a separate cut into the central drain of the riser.
• If the pump is mounted in such a way that the horizontal pipe is below its level and has a large length, then a 0.7 bar valve must be installed at the highest point of the pipe, which will allow air to ventilate the system after the unit is turned off.
• All do-it-yourself pipe connections should be made only by soldering or a high-quality connection using a sealant.
• It is forbidden to use a flexible corrugated pipe for sewage. Only PVC or polypropylene.

As you can see, it is not at all difficult to mount a forced pump with your own hands. And the result of the work carried out will ensure the efficiency of the sewer system.

What if the sewer outlet is higher than the plumbing outlet? How then to organize the removal of wastewater? In private houses, a pit was made into which drains were collected, from there they were pumped with a submersible pump into a sewer or septic tank. Today there is another solution - a sewage pump. In many cases, its installation is cheaper, and even easier - that's for sure.
