Sewer pipes or rainwater pipes can become clogged. There are various reasons for this. Wastewater conveyed in the pipes can cause sedimentation and eventually partial or a complete blockage. A broken pipe can also cause a blockage, for example due to sagged pipes or crushed sealing rings that reduce the pipe cross-section and prevent unhindered drainage. In the kitchen area, drain lines are often clogged by grease, food residue or lime scale. In the bathroom, it is deposits and residues of wet wipes, toilet paper, hair, lime scale and urine scale. To loosen these deposits, the pipe cleaning machine is used.

In case of light blockages, pipe cleaning can be performed with the drain cleaning pump.
