How does a grinder pump work?

Shower drainage with a Pentair Plancofix Plus grinder pump Sewage pipes have a much larger diameter than clean water installations. In the latter, there is also pressure, supplying liquid to the floors of the building, to any end point. Used, dirty water flows downwards much more frequently by gravity. However, it is not always possible to run sewage pipes in such a way that everything flows into the sewage system or septic tank. In such cases it is necessary to create pressure. Pump grinders are used for this purpose.

Their task is to crush larger elements floating in the used water and push them further towards the sewage system . For this purpose, a tank is used to retain toilet paper or food remains. The knife here chops everything up so that smaller pieces can flow through the safety eyelets into the pump. This pumps the sewage further - to the septic tank, which may be located even several dozen meters away, above the installed grinding pump.

Pump grinder and pipe diameter

When building a sewage system, you can meet SFA Sanivite Sil pump-shredder (dishwasher, laundry room, bathroom without toilet) with two types of pipes. Gray ones are intended for use inside the building. Their diameter starts from 32 mm. The largest ones reach a size of up to 160 mm. The sewage system continues outside with orange pipes with diameters ranging from 110 mm to 500 mm. This allows dirty water to flow down by gravity without larger contaminants getting stuck.

The use of a pump with a grinder means that all elements flowing with water have a much smaller diameter. In addition, the flow of liquid is forced by the pressure created by the device. Thanks to this, you can use pipes with a diameter of 22 mm to 40 mm, without the risk of blockages.

Application of a pump with a grinder

When can a pump chopper be very useful? There can be many such situations. The most common examples are:

  • Construction of an additional bathroom in SFA Sanibest Pro feces grinder wc+4 building without the possibility of installing a large-diameter sewage system.
  • An additional point of use far away from the house, and therefore often from the septic tank.
  • Installation of sanitary facilities in the basement, below the level of drainage to the septic tank or sewage system.
  • The need to pump sewage from one septic tank to another (for example, due to problems with access to a septic tank).

Generally, a pump with a grinder is useful wherever sewage cannot flow by gravity (usually due to height or distance differences) or it is not possible to use sufficiently large sewage pipes. However, nothing prevents such a device from complementing an existing and operating installation in order to reduce the risk of blockages or sewage spilling out.

Which pump grinder model will be suitable?

In the case of a shower, it is worth choosing shower drainage with a Plancofix Plus pump . It is very low, so it will fit under any shower tray. Moreover, it is characterized by quiet operation and low energy consumption. Unfortunately, it is too small a device for the kitchen or bathroom.
