A sewage pump for the shower

The trend is towards the additional shower in the bathroom. But there are also other reasons more and more, which require a shower. Often, however, the sewage pipes are not available to connect a shower accordingly. Remedy here creates a sewage pump.

Numerous reasons for extensions or remodeling of showers

In recent years, it has been observed that people are no longer satisfied with a bathtub alone. The trend is for additional shower. In addition, existing showers but also often be rebuilt. Floor-level showers not only look particularly chic, they are also an important aspect of barrier-free living.

The drainage gradient can often not be sufficiently produced

In addition, there are numerous extensions of living space through attic or cellar extension. However, especially in the upper floors, it is often even more difficult to gain floor height in order to install sewer pipes with a sufficient gradient. Even in old buildings, the possibilities are often massively limited.

Various wastewater pumps for showers with different requirements

The specialist retailer offers a whole range of solutions for such problems. These are wastewater pumps that can be adapted to the special requirements of shower tray installation or that also help to implement barrier-free living. So it is important that you choose a shower drainage pump according to the direct requirements:

  • barrier-free living or walk-in shower trays without sewage drainage options
  • additional installation of a shower tray or already laid sewage pipes
  • as a result, too low construction heights with consequently less gradient in the sewage pipe
  • Wastewater connection to conventional drainage (greywater) or sewage effluent (black water)
  • In addition to shower wastewater, further wastewater must be pumped (washbasin or urinal)

Ground level and barrier-free showers

According to the respective task the specialized trade offers numerous solution approaches. Especially for barrier-free living and very little space, the installation of a sewage pump below the level of the shower tray would be an option. Many sewage pumps are out of the question because of their construction heights.

Observe guidelines and DIN regulations

However, there are particularly shallow sewage pumps (construction height of about 10 cm) that can be installed in the screed floor. However, in addition to the drainpipe, a conduit for the electrical installation must be considered. In this context (electrical installation), in addition to the DIN standards that apply to sanitary facilities, the guidelines of the VDE (Association of Electricians) must also be taken into account.

Advantages and disadvantages of small sewage pumps

The advantage to be highlighted is the implementation of a floor-level shower area. As a disadvantage, the properties of a small pump come into play. In the flow rate, these are usually limited to flow rates of about 20 liters per minute. Soundproofing, on the other hand, can be implemented by placing the wastewater pump in a soundproofed bath.

Powerful sewage pumps

In addition, there are also sewage pumps, which can be mounted directly next to the shower tray, for example in a base cabinet. These pumps not only provide a larger flow volume. Often, further wastewater can be connected and pumped out. Including urinals, sinks or PDs. Depending on the system, the pumps are equipped with a non-return valve so that no waste water can run back.

Collect wastewater or vacuum immediately

In addition, however, a distinction can also be made as to whether the wastewater should first be collected in a pump sump or pumped off immediately even at the lowest outflow quantities. This is solved by appropriate stop systems such as floats. However, it is important in such systems that the pumps do not run dry.

Pump systems for sewage pumps

Depending on the system, it may be suction pumps or centrifugal pumps. The latter pumps have the advantage that, depending on the ball throughput size, a certain amount of solids may also be present in the wastewater. For this, the intake area must be completely exchanged in the liquid to be sucked. Suction pumps, on the other hand, can even pump out small amounts of water.

Tips & Tricks

In cellars it is recommended to compare a conventional wastewater pump for the cellar with a lifting system with sump.
