Technical characteristics of Sololift sewage pumps

The classic sewerage system works on the principle of gravity water supply through the main pipeline, which is located at an angle. However, such a design can not always be installed. An alternative option is to use the Sololift pumping equipment, which is distinguished by its compact dimensions, quiet operation, easy installation and practicality. The system has a self-cleaning device, due to which the operation of the pump is very simple and does not require unnecessary effort. The equipment manufacturer is the Danish company Grundfos, which produces pumping units and accessories for them.

Application area

The pumps are used for pumping wastewater in buildings where, for technical reasons, it is impossible to install a sewerage system that works on the principle of gravity. The manufacturer offers several models for pumping black and gray wastewater. The following nodes can be connected to the system:

• baths, shower cabins;
• shells;
• bidet;
• toilets of various designs;
• washing machines and dishwashers.

Due to their small size, Sololift stations can be combined with floor-standing and wall-mounted devices, so they do not spoil the design of a bathroom or a toilet.

Pros and cons of the design

The equipment has the following advantages:

• efficient work even when connected to a small diameter pipeline;
• small dimensions, the ability to mount the device in a confined space;
• convenient operation;
• a number of improved models have a vortex design, due to which blockages are not formed in the system;
• no need to use an expensive installation tool;
• compatibility with various types of interior.

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

Design features

The principle of operation of the Sololift sewage systems is quite simple. The model is used as the main wastewater receiver, the secondary outlets are connected using auxiliary pipes with a diameter of 5 cm, which are located in the lower sector. The inlet lines for drains can be implemented using equipment for a standard sewer network, and the outlet elements serving to drain the liquid must be reliably sealed, since pumping is carried out under pressure. That is why it is important to purchase branded accessories during installation, including a check valve and other plumbing fittings.

The pump itself is located in the housing with a separator element and knives that grind large waste. The principle of operation lies in the operation of an automatic unit, which turns on when the tank is filled and activates the pump, the device is connected to a standard power supply. Energy consumption even in younger models is small, so the installation of pumping equipment allows you to mount an efficiently working sewer network in a private house or apartment.

System varieties

The characteristics of the Sololift sewage pump differ depending on the specific model.The manufacturer produces a line of 5 devices, the following types are suitable for installation in a bathroom:

• Sololift2 WC-1. The unit is designed to connect a sink and a toilet, the power is 620 W, the volume of the tank is 9 liters. The set includes a shredder that crushes large waste. The throughput of the system is 149 liters per minute.
• Sololift2 WC-3. The model is used to create a forced-type sewage system in cottages and country houses, it is characterized by increased power and allows you to connect three additional consumers, in addition to the toilet bowl. The owner can supply such a pump to operate a sink, shower stall, bathtub, bidet or other plumbing fixture.
• Sololift2 CWC-3. The device is equipped with a built-in cutting mechanism, the power is 620 W, and the capacity is 137 liters. This accessory is suitable for installing a wall-mounted toilet or urinal and three additional devices to choose from.

The manufacturer produces models for gray drains, differing in characteristics and dimensions:

• Sololift2 C-3. The power is 640 W, the system processes up to 204 liters of wastewater per minute. The model is not equipped with a chopper, but allows you to connect an extended range of consumers. It is suitable for draining liquids with temperatures up to 90 degrees.
• Sololift2 D-2. This model is the most compact and lightweight, with a power of 280 watts and a throughput limit of 119 liters.

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. The installation can be done independently, the technician is equipped with instructions. To work, you will need several straight screwdrivers (8 and 2.5 mm), pliers with a 5 cm opening, a socket and a wrench. For the system to work without interruption, you need to complete the installation in the correct sequence. Algorithm of actions:

1. Pick up pipeline elements, sealing parts, sealant, and other consumables.
2. Fix the Sololift pump on a vibration-insulating material, observing the minimum distance to the wall or the connected consumer of 10 mm.
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 that is waterproof, otherwise leaks will quickly appear.
5. Fix the outlet pipe with pliers and connect the pump to the mains.

Upon completion of the work, you will need to check the system for operability, test the pump itself, make sure that there are no water leaks in the network. In the absence of skills or tools, it is recommended to entrust the installation work to specialists so as not to encounter problems with the further use of the sewage system.

System operation and maintenance

Maintenance of the Sololift station implies regular cleaning of filters, water tanks and moving parts. For this, special chemicals are used, the cleaning process includes the following steps:

1. Disconnect the pump from the power supply.
2. Remove the cover that is located at the top.
3. Pour the detergent into the container.
4. Switch on the system and drain the cleaning fluid after a few minutes.
5. Perform pumping with plain water.
6. Close the lid.

The intensity of service depends on the frequency of operation, the number of connected consumers, the quality of wastewater and other factors. At a standard level of water hardness, the system is cleaned every 3-4 months, the filters are changed as deposits form. If the internal elements are worn out, it is better to entrust the replacement to specialists.
