Sololift for sewage: principle of operation and features of its application

The sewage system can function properly only if the pipes in it are located under a slope. If the bias turns out to be insignificant, then the likelihood of blockage may increase significantly. Because of this, a harmful sediment will accumulate on important parts of the system, which is able to impede the movement of wastewater. That is why the plumbing either has to lift or lower the sewer. To resolve this problem, you can use a device such as sololift.

To understand how important and necessary sololift is in the sewer system, it is necessary to consider in detail exactly what it was designed for. But first you should make a small digression and figure out what the sewer installation is like.

If we consider these devices from the point of view of their design, then we can say that they are pumps equipped with special grinding components. Most often sololifts are installed in private houses, where there are difficulties with the riser of the sewer system, located in an inaccessible place, or with a too small inclination, which is not enough. Of course, these devices are often put and conditions of city apartments, for example, when repairing or redevelopment.

As for the immediate scope of such units, here we can distinguish:

• the ability to connect a washing / dishwasher at a great distance from the sewer;
• the possibility of installing plumbing fixtures, for example, toilet bowls, below the sewer point;
• moving the bathroom to the other half of the living space.

Today there are often functional variants of sololifts on sale, equipped with special grinding mechanisms. Such models are designed for grinding the contents of the drain. Due to these features of functioning, such types of devices take an active part in the normal and fastest possible evacuation of blockages.

Such pumps, along with other sewage devices, have both strengths and weaknesses. They are used in many homes. Let's get acquainted with the pros and cons of the sololifts.

To begin, consider the positive qualities.

• Automatic self-cleaning function. Since these units are equipped with a sloping bottom, various waste products do not accumulate in their tanks. When starting the pump, a significant flow rate of water provokes the formation of a vortex thrust that cleans the bottom of the tank from any precipitation.
• Compact dimensions. The lion's share of sololifts are designed for a volume of water in 3-5 liters. For this reason, the body of such units is performed with very modest dimensional parameters. However, in such conditions, the flow rate of wastewater takes at least 40 l / min., Which significantly exceeds the drain of absolutely any sanitary unit.
• Silent work. Due to the fact that such a pump is always in the water and does not draw air in, no loud noise is emitted from it in the process of supplying liquid.
• Ease of installation. Sololift is a fully automated device that just needs to be connected to the plumbing, the receiving pipe and the socket (220 V).It should be noted that this technique can be docked with pipes of different diameters. But we must not forget about one important requirement - all connections must be as tight as possible. That is why not only an experienced master can cope with the installation of a sololift, but also an ordinary user who does not have a special education.

• Reliability. Sololift is considered a very strong, durable and wear-resistant model of sanitary equipment, so you can safely talk about its high reliability.
• The possibility of redevelopment. This advantage is considered the most significant. With solo lifts you don’t have to worry about height differences. In addition, with such equipment there is the possibility of installing engineering plumbing units.
• Tightness. Such systems are distinguished by high tightness, which allows to avoid leakages.
• Low start. Due to this quality, users have the opportunity to install a modern flat shower.
• Functionality. It can be installed both in a private house or at the cottage, and in a city apartment. In addition, connect the sololift will turn out not only to the toilet, but also other sanitary appliances, for example, to the sink or shower.
• Reliable fasteners. The fasteners of this technique are such that they do not fall out in the process of its work and installation.
• Compliance.
• Wide range of. To date, there are several large and well-known manufacturers, offering a choice of buyers high-quality models of sololifts of any modifications.
• Simple elimination of blockages. Even if the unit has been clogged, it can easily be removed by removing the cover at the top of the tank.

Such a device as a sololift, has become very popular and in demand recently. As a rule, consumers leave positive feedback on such models.

However, this does not mean that they are devoid of flaws.

• First of all, it should be borne in mind that it is necessary to treat the tanks of these devices very carefully and carefully. In no case should any chemicals or other chemical compounds, characterized by aggressive corrosive action, penetrate into them.
• We must not forget that the sololift must be connected to the mains (preferably uninterrupted). This indicates the volatility of such technology.Without electricity, the pump simply will not start.
• Some consumers are not satisfied with the fact that such high-tech systems somehow have to be subjected to periodic cleaning using special formulations.
• Many consumers attribute their high cost to the significant shortcomings of such systems. In addition, the sololift service is equally expensive.

The structure of the sololift is quite simple.

Such equipment consists of the following parts:

• storage tanks;
• submersible pump;
• check valve element;
• receiving filtering component;
• grinding systems (not available in all models);
• carbon filter type.

As for the principle of operation of the sololift, everything is also quite simple here. Such a device functions as follows: it draws liquid through the filtering receiving system into the inner part of the reservoir responsible for accumulation. The cutting mechanism in the form of an impeller, located in the input part of the device, very quickly crushes any incoming inclusions. After that, the effluent is moved to the inside of the discharge pipe.As for the discharge that has undergone the appropriate treatment, a special valve of the shut-off type, represented by a valve, prevents its reverse discharge.

Since in such devices there is a special carbon filter that is installed on top of the sol-lift, odors from the sewers do not penetrate into the living space. Thermal relay of hydrodynamic type controlled filling level. As for the check valve system, in this case, it moves with the help of pressure pipes in the course of filling the tank. The autostart float sensor captures the degree of fullness of the sewage equipment, and the pump begins to move after the corresponding signal from the relay.

Such sewer installations have the following technical characteristics:

• work with water, the temperature of which can be from 0 to +45 degrees (if the temperature regime reaches 90 degrees, then it is recommended to use the model of brand C-3);
• the working head of such a station is 9.9 m (the capacity parameter at the same time reaches 4.5 m3 / hour);
• most models have a useful protective system against overheating;
• To operate such a pumping system, a power grid with a voltage of 220-230 W is required.

The choice of sololift should be approached carefully and deliberately. A high-quality model of a suitable modification is sure to serve its owners as long as possible.

Consider in detail what criteria you need to pay attention to, choosing a similar pumping station for the sewer system.

• Initially, it is important to determine the number of all sanitary units that you are going to connect to the device. You should also consider the total number of drains.
• If you plan to connect several plumbing fixtures at once, it is recommended to purchase models in which there is an additional connection.
• When choosing a suitable model, it is important to consider the specific installation location of the sololift, as well as its power level.

Here it is important to take into account that different modifications of sololiths are used for different purposes.

• wc model is designed to connect only the toilet;
• model wc-1 can be used to connect the toilet and sink;
• model wc-3 is suitable for connecting a toilet, sink, shower stall and bidet;
• cwc-3 is used to connect hanging toilet, sink and shower;
• Model C-3 is used to connect the washing machine and kitchen sink;
• d-3 allows you to connect the shower stall and sink.

In addition, when choosing a suitable model, you should rely on the following parameters:

• number of connected objects;
• the greatest height for vertical pumping;
• the largest distance for horizontal pumping;
• device performance level;
• consumed power level;
• allowed temperature mode of pumping fluid;
• device dimensions;
• its weight;
• materials from which the internal part of the units is made (you should choose options that are not susceptible to corrosion);
• price;
• possibility of self-assembly.

Experts strongly recommend to buy only high-quality models of sololifts, issued by major European brands.

Currently, some of the most well-known manufacturers offering durable and robust units are:

• Grundfos;
• Lowara;
• SFA;
• Dab;
• Wilo.

Of course, branded products from these brands can be quite expensive, but the highest quality and trouble-free operation of branded solo-lifts more than justifies the high price.

There are several models of sololifts. Let's get acquainted with their distinctive features and operational characteristics.

This setting is very modest in size. It is used for the purpose of pumping waste from the sink and toilet bowl. In these models often put very powerful engines, as well as choppers. That is why such products easily cope with rather large inclusions.

The main characteristics of these models:

• weight - 7.3 kg;
• tank volume - 9 liters;
• dimensions are 452.5 × 346.7 × 175.5 mm.

These products are usually mounted on the floor, using fasteners such as dowels, supports or screws. Also, flexible pipes and adapters are used, which can be selected for pipes of absolutely any diameter.

Such units have the same positive qualities as the WC-1, however, it is allowed to connect not only a toilet or a washstand, but also a shower cabin or a bidet.Such equipment capabilities are due to the fact that it contains 3 additional pipes. It is necessary to take into account only that WC-3 models are intended for toilet bowls, in which the volume of drain is 4-9 liters.

Technical characteristics of such products:

• weight - 7.3 kg;
• self tank - 9 l;
• dimensional parameters - 441.6 × 452.5 × 175.5 mm.

Such units are characterized by very small sizes. In addition, they contain additions in the form of powerful shredders, which are used to transfer wastewater from the toilet bowl, bidet and hand wash basin. Often this model is installed in a variety of niches with doors, because it has modest dimensions.

CWC-3 is highly reliable and durable. This product is equipped with a very powerful electric motor, so even if such elements as feminine hygiene products get into the drains, the system does not fail. The bottom of the tanks in such models is slightly rounded, so there can not be accumulated precipitation.

Characteristics of such models:

• weight - 7.1 kg;
• capacity - 9 l;
• Dimensions - 495.1 × 538.4 × 164.2 mm.

This model of sololift is used for pumping gray waste, which does not contain feces and other large inclusions.D-3 will be able to simultaneously connect to the soul, and to the sink, and to the bidet. However, it should be borne in mind that these models are not allowed to be connected to the toilet, because they lack a special cutting mechanism.

In this model of sololift there is a fairly powerful electric motor, crankcase and shaft made of stainless steel. Case D-3 is completely sealed. Due to the special form, no precipitates accumulate in it. These models are installed very simply - for this you only need fasteners and screwdrivers. In addition, they are also easy to dismantle, if necessary.

Characteristics of D-3:

• weight - 4.3 kg;
• capacity - 2 liters;
• dimensions - 380x165x217.

This installation differs from other options in that it can pump over drains whose temperature ranges from 75 (in continuous mode) to 90 (not more than half an hour) degrees. However, in these products there is no powerful cutting mechanism, so this sololift cannot cope with waste from the toilet bowl. At the same time it is permissible to connect a washing machine, a dishwasher and sanitary appliances (but no more than 3 one-time connections) to it.

Model C-3 has a magnetic float switch. Its level can be changed to improve performance parameters.If required, this part can be removed completely for the purpose of maintenance of the unit.

Consider the characteristics of this model:

• weight - 6.6 kg;
• capacity - 5.7 liters;
• dimensions - 493x158x341.

Relatively recently, improved models of sewage equipment appeared on the market.

They have the same positive characteristics as the previous copies, supplemented by the following parameters:

• increased power level;
• equipment in the form of a vortex system that is not afraid of blockages;
• high-tech grinding mechanism made of high-strength materials;
• ultra-compact dimensions;
• guaranteed no leakage, increased reliability characteristics.

In the line of units "Sololift-2" there are such subspecies of sewage equipment:

• WC-1,2,3;
• P-3;
• D-2.

Installation and connection sololift can do it yourself. It is important not only to follow a fairly simple instruction, but also to observe a certain angle of inclination of the device, which allows you to send solid waste to the branch pipe. If you decide to do the installation yourself, then you should stock up on the following standard tools:

• screwdrivers profile "straight slot" - 8 and 2.5 mm;
• special multitasking forceps with a characteristic opening of 50 mm;
• ratchet wrench;
• socket wrench.

Before proceeding to the direct installation of sololift, it is very important to make sure that all the necessary parts, as well as seals, are available. If necessary, order service kits.

Let us consider in stages how the installation of a forced sewer system is carried out.

1. First you need to pick up pipes that have a suitable diameter.
2. After that, it is possible to install and fix the sololift on the anti-vibration material laid earlier. It is very important to maintain a very small distance from the plumbing unit to the wall - no more than 10 mm.
3. The next step is to connect the device to the outlet of the sanitary equipment itself.
4. If you install the sololift in a separate niche, then it is recommended to supplement it with a firmly fixed door. This detail will give the chance to carry out audit, and also will allow to service equipment in the course of its use.
5. After that, all the joints and seams on the pipes will need to be properly smeared with high-quality waterproof sealants.
6. The final stage will be fixing the exhaust pipe with clamping pliers. After that, you need to call electricians who can properly connect the device to the mains. During the trial run of the mounted unit, it is very important to check the tightness of the connections of all the pipes. In addition, you will need to check the operation of the pump.

Sololift, like any other equipment, may be subject to one or another damage. Consider the most common problems encountered by users who have similar installations in their dwellings.

• The motor in these devices may jam and overheat. This may be due to the penetration into the interior of the device of solid elements. Such a malfunction can be eliminated by cleaning the drain station or by a more radical method, by replacing the engine.
• Also in such units, the temperature regime is often lost. In this case, the engine may fail due to excessive overheating. Such problems often manifest themselves due to improper selection of the installation, which is simply unable to ensure the discharge of hot liquid. It is possible to get rid of such problems only by replacing the pumping station with another model with suitable technical characteristics.
• The electric motor in sololiftah can constantly overheat. This is due to the untimely cleaning of important sites of sewage equipment. To get rid of this problem, you may have to repair the motor or replace the pipeline with a larger diameter pipeline.
• A pump in such a system can fail due to freezing. As a rule, this happens in the winter in unheated rooms. In such conditions, the device may be deformed. In this case, the pump will either have to be repaired or even replaced with a new one.
• Another problem of such a unit can be a burnout of the engine. Such a serious failure occurs due to the fact that water enters the motor.In order to resolve such problems, you should diagnose the existing device. Also it is necessary to eliminate the reasons why moisture gets into the motor.
• Some users are faced with the problem of sticking and burning an electric motor. In the course of draining thick and sticky liquids, sticking of rotating parts of equipment can occur. In this case, it is often necessary to completely change the engine.

Independently installing sololift, It is necessary to adhere to the following useful tips from experts.

• Assembling such pumping installations, one should not forget about the slope of sewage free-flow pipelines at 3%, and pressure pipes - 1%.
• In pressure pipelines, it is better to install vertical sections immediately after the sololift itself.
• When connecting devices of the WC brand to the toilet, it is advisable to use a very short element of the pipeline.
• Also during the installation work, access to the pump station cover should be provided so that in the future it can be serviced or repaired without any problems.
• Experts recommend installing soloift as close as possible to the toilet (if we are talking about a bathroom in a house or apartment).The minimum distance will provide the most efficient drainage, as well as high performance characteristics. The main thing is not to forget about the distance from the walls of 10 mm.

If you decide to install such a practical unit in your home as a sololift, then you should operate it correctly so that it lasts as long as possible.

Such sewage equipment must be periodically subjected to proper cleaning. This also applies to the filtering components of technology. As a rule, specialized detergents are used for this.

To clean a sololift, you should follow these simple instructions:

• disconnect the product from the mains first;
• then remove the top cover of the equipment;
• after that you need to pour detergent into the container of the sololift;
• then you need to start the pump and drain the liquid;
• then it is necessary to pump the equipment using running water;
• Finally, do not forget to close the unit cover.

In the process of cleaning the sololift, you can replace the carbon filter. This procedure is mandatory if the equipment is surrounded by an unpleasant characteristic odor.

If there is a unit such as a sololift in your home, then you need to take into account that it is not designed to destroy sodden pulp and other large items (for example, diapers or sanitary pads). If the sewage equipment is still clogged, you will need to remove the cover at the top and clean the container manually (you will also need to disconnect the unit from the power supply beforehand).

If we are talking about drains from the bathroom or toilet, then there is no need to worry - the sololift will easily cope with the waste from these premises (except for the large items mentioned above). However, if we are talking about the kitchen, then there is usually a place for domestic waste water with grease. In such cases, experts recommend to fix the system before installing the pump.special grease trap.

Worn parts of such sewage equipment should be replaced. This should be done in time for the sololift to work properly and efficiently.

In case of serious damage, it is better to contact specialists. Self-repair can only further harm the equipment, especially when it comes to faults of high complexity.
