Sololift pump for sewerage: features of selection, repair and technical operation of equipment

In cases where gravity evacuation of wastewater is not possible, forced pumping units are used. Such equipment prevents the formation of blockages in drain systems and allows plumbing fixtures to function fully, regardless of their number and location in an apartment or private house. Today we will analyze in detail what Sololift for sewerage is, what problems such installations solve, and also talk about their advantages and disadvantages of devices.

Compact pumping station for sewerage

Sololift - what is it?

Owners of private houses and apartments quite often face the problem of difficult drainage of water into the sewer. To solve it, it is enough to install a pumping station to pump liquid.

Forced action pump for toilet

The best choice for ordinary people would be to purchase a compact Sololift device, which will ensure uninterrupted operation of the wastewater system. In addition, such equipment can be installed anywhere in a residential or utility room, regardless of the level at which the plumbing fixtures are located. Sololift is a household sewer pump that automatically and forcibly transports wastewater into the sewer pipeline.

There are models of devices with a mechanism for grinding the contents of the drain, which ensures its normal evacuation and eliminates the formation of blockages. A home forced sewer pump is capable of lifting wastewater to a height of 7-9 m with vertical pipes. This allows equipment to be installed in basements below the level of plumbing fixtures in the home.

Scheme of operation of the pumping station located below the drain point

The station is also capable of evacuating waste liquid over a distance of up to 100 m along a horizontal sewer line. Sololift pumping units have a stylish design and compact dimensions, so they are perfect for the interior of kitchens, toilets and bathrooms.

Advantages of the device

• compact body of laconic design;

• connects to small diameter pipes, which makes it possible to reduce costs on materials;

• suitable for use in residential premises, offices, public buildings;

• connects to pipelines of different diameters;

• some models pump clogged drains;

• simple installation;

• does not require complex maintenance;

• has a long service life.

Sololift sewer pump: solving problems with wastewater drainage in a private house

Sololift household appliances are used for forced pumping of liquids and sewage that cannot be drained by gravity. Such equipment makes it possible to install plumbing fixtures below the point of entry of the drain into the sewer pipe. For example, a bathroom or toilet can be moved to the basement.

Scheme of operation of the device with the grinding mechanism

In the presence of an old sewer system, drainage is often difficult due to the narrowing of the pipe lumen. This problem can be solved by installing a fecal pump with a grinder for the toilet. There is a carbon filter inside the station, which absorbs the unpleasant smell of sewage.

How to change the slope of a pipe

There are only two ways to change the slope of the pipe:

• lift a plumbing fixture (bathtub, sink, toilet, washing machine, etc.);
• make the entrance to the local or central collector lower.

Both of these methods involve significant difficulties. It is not always possible to raise a bathtub or toilet without affecting the ease of use, and it is even more difficult to lower the entrance to the central manifold.

Sololift for Grundfos sewerage: advantages and disadvantages of equipment

Grundfos pumping stations are rightfully considered one of the best equipment for plumbing and sewer systems on the market. Sololift units have a durable body, and all structural parts are made of high-quality materials. This ensures equipment reliability and long service life.

Among the advantages of pumping systems, it should be noted that there is no need to carry out work to clean structural components. All models are made in such a way that impurities and debris do not accumulate in them. In addition, the operation of the device is characterized by a low noise level, which creates additional comfort from its use.

The small dimensions of Grundfos devices make the equipment compact and make it possible to install pumps even in limited space. Sololift copes well with thermal loads and is resistant to water pressure, so you don’t have to worry about pump breakdowns. The disadvantages of household pumping stations include the fact that the equipment operates from the mains and requires constant switching on. To ensure uninterrupted drainage of the sewer, care should be taken to connect the installation to an autonomous power source.

Pros and cons of the design

The equipment has the following advantages:

• efficient operation even when connected to a small diameter pipeline;
• small dimensions, the ability to install the device in confined spaces;
• convenient operation;
• a number of improved models have a vortex design, due to which blockages do not form in the system;
• no need to use expensive tools for installation;
• compatibility with various types of interior.

One of the disadvantages is the overpriced device. Another problem is complex repairs that are difficult to do on your own. Most owners turn to professional repairmen to fix breakdowns, which requires additional costs. On the other hand, with proper operation and initially correct installation, the system rarely needs maintenance.

Sololift design and equipment

The Sololift household installation consists of a storage tank (housing) and a pumping mechanism. There is a special sensor inside the device that monitors the liquid filling level.

Table 1. Structural components of the Sololift pumping station

How does the drainage system work?

Sololift2 Grundfos sewage pumping stations are equipped with an electric motor and a liquid level sensor. In addition, the structure is made of composite tanks, the storage tank has spherical walls, and the bottom is inclined in the direction of the pump.

This design and layout option minimizes the likelihood of sediment forming on the bottom and walls of the tank. The sensor ensures that the engine turns on only when necessary, which saves energy.

The principle of operation of pumping stations is as follows: wastewater flows into the tank and reaches the control level. The sensor gives the engine a start command, and the liquid is pumped into the public sewer system. When the level drops to the set values, the motor turns off and the pump stops working.

The principle of operation of the Sololift sewage pumping unit

The operating principle of household sewerage pumps is quite simple. There is a sensor inside the station device. As soon as the water reaches a certain level, it turns on and sends a signal to the pumping unit and the grinding device.

After they are activated, the liquid with processed sewage is transported into the main drainage system. Electrical equipment is switched off automatically. Depending on the number of points of consumption, a sewage pump in a private house or apartment may have several inlet pipes. They are used to connect plumbing fixtures. The installation also has an outlet through which the liquid is drained.

Advice! To connect equipment such as washing machines or dishwashers, as well as to organize the drainage of sinks and bathtubs, it is recommended to install models with a heat-resistant housing.

Rules of operation and maintenance

Maintenance of all sololift models involves systematic cleaning of the equipment and the filter system installed inside it. For this purpose, special detergent compositions are used.

Sequence of cleaning pumping equipment:

1. Disconnect devices from the electrical network.
2. Remove the top cover of the device.
3. Pour detergent into the reservoir.
4. Turn on the pump and drain the liquid.
5. Pump the unit with running water.
6. Close the unit cover.

The electrical power must be turned off when cleaning the filter, which is removed, washed and installed in its original place.

Some models are equipped with a magnetic float switch installed at different levels. During maintenance, such a float must be removed.

How to choose a Sololift sewer pump for a toilet and sink - recommendations from our editors

Before buying a Sololift for sewerage, you should first study the technical parameters of the device, as well as decide on the intended use. If renovation work is to be done in the house with subsequent redevelopment and relocation of equipment, preference should be given to pumping stations with several inlets.

Types of devices compatible with Grundfos pumping stations

It is extremely important to take into account the maximum water temperature at which normal operation of the equipment is allowed. Also, when choosing a pumping station, you need to take into account the method of its installation, since the higher it is located, the greater the power consumption will be. If you choose the wrong installation (in terms of power and performance), there is a high probability that the pump will not withstand the load and will burn out. For this reason, you should select a system with a small margin of basic technical parameters. We offer you to watch a video that will allow you to quickly understand the criteria for choosing Sololift pumping systems.

Video “Criteria for selecting Sololift pumping stations”:

A few words about Sololift markings

When choosing a pumping unit, you need to pay attention to the product labeling. This nuance determines the installation location, functionality and everyday tasks that can be solved using the equipment.

The manufacturer uses capital letters of the Latin alphabet to label products. It looks like this:

• WC – these models have a built-in grinding mechanism. The station is designed for the removal of black (fecal) waste and can be connected to floor-mounted toilets.
• CWC - this category of equipment is also equipped with a grinder and is designed for the removal of fecal waste. However, such models are designed for wall-hung toilets.
• C and D – pumps for removing gray (fecal-free) wastewater, suitable for any plumbing fixtures except toilets.

In addition, the marking of each product includes a numerical designation: 1-3 . This indicates the number of additional outlets in addition to the main drain. Essentially, the numbers indicate the number of plumbing fixtures connected to the pump.

Installation of forced sewage pump Sololift

Despite the ease of installation work on installing Sololift pumps, you should follow some rules to avoid mistakes. The drain pipe should not have any bends, as this will make it difficult to push out the drain water. If you plan to install a pumping station to drain liquid from shower cabins (bathrooms), it is recommended to connect the equipment at the lowest points. In addition, the drain must be equipped with a filtration system to prevent hair and other small objects from getting inside the equipment.

Option for installing a pumping station in a toilet

Before carrying out installation work, it is necessary to check the installation package and make sure that there is a check valve (if it is missing, dirty water will flow back into the system). You also need to install a material on the floor under the unit that will absorb the vibrations of the pump. The pipes must be tightly connected to each other using sealant and seals. As a rule, manufacturers include all the components necessary for installation, so there is no need to purchase screws and other fasteners.

Connecting the pump connections

Upon completion of installation work, the system is checked for connection quality. If leaks occur, it is necessary to eliminate defects at the joints.

Installation Features

During installation, it is extremely important to ensure the correct angle of inclination of the pumping equipment, otherwise the movement of waste will be difficult. You can do the installation yourself; the equipment comes with instructions. To work, you will need several straight screwdrivers (8 and 2.5 mm), pliers with an opening of 5 cm, a socket wrench and a wrench. In order for the system to operate without interruption, installation must be completed in the required sequence. Algorithm of actions:

1. Select pipeline elements, sealing parts, sealant, and other consumables.
2. Fix the Sololift pump on the vibration-isolating material, maintaining a minimum distance of 10 mm to the wall or connected consumer.
3. Connect the required devices (toilet, sink, bathtub, bidet, etc.) to the outlet pipes.
4. Treat connection points and joints with sealant. It is important to choose a substance with water-resistant properties, otherwise leaks will quickly appear.
5. Secure the outlet pipe with pliers and connect the pump to the power supply.

Upon completion of the work, you will need to check the system for operability, test the pump itself, and make sure that there are no water leaks in the network. If you do not have the skills or tools, it is recommended to entrust installation work to specialists so as not to encounter problems in the future use of the sewer.

Maintenance and repair of the Sololift pump

Table 3. Main types of faults and methods for solving them

The removed power unit of the pumping unit
The principle of maintenance of forced drainage systems for Grundfos Sololift sewerage is to comply with the fluid temperature specified by the manufacturer and periodic inspection. It is also necessary to prevent all kinds of objects and aggressive chemical compounds from getting inside the unit.

Preventing a dirty pump

Connection to sewerage

Connecting the sololift to the sewer system provides for a distance to the plumbing fixture of no more than 50 m. Increasing the distance will lead to disruption of the station. The sololift system for sewerage provides the correct slope of the pipes after vertical lifting. If pipes are laid at the wrong angle, the operation of the sewer system will be disrupted and the likelihood of blockages will increase.

Dependence of pipe diameter on distance

To connect to plumbing fixtures, it is made using adapters included in the delivery package of the sololift. The device itself must be firmly fixed to the floor.
