Cleaning with the right water pressure

The regular maintenance of drain systems consists of periodic flushing of the drain pipes. Using the correct pressure is an important aspect of doing this properly.


Flushing out drain pipes with excessive water pressure can cause damage, both to the drain pipe itself and the soil surrounding it. The water penetrates the wall of the drain, which can destroy the filter cloth. Too much pressure can also loosen the soil around the drain pipe and saturate it with water. After the cleaner nozzle is reeled in, the water pressure in the pipe drops again and soil particles from outside can enter the pipe with the draining water. These soil particles may then remain in the wall or sheath. The consequence is damage to the structure of the ground surrounding the drain pipe. The drain system will not work as well and will also become clogged more quickly.

Cleaner nozzle

When cleaning drains it is therefore extremely important that this is done with a safe, low level of water pressure. The specially developed Sieger cleaner nozzle provides optimal cleaning when the water pressure at the cleaner nozzle is just 7 to 10 bar. This pressure level is adequate to loosen the contaminants in the drain pipe. The loosened contaminants are then flushed past the cleaner nozzle and flow out of the drain pipe.

Water capacity

To ensure that the drain pipes are flushed thoroughly it is important that the pump has sufficient water capacity. The piston diaphragm pump used by Sieger has a maximum capacity of no less than 142 litres per minute.

Sieger drain cleaner

Because Sieger drain cleaners feature a cleaner nozzle that works with low water pressure and a pump that provides more than enough water for rinsing clean, they are the safe way to maintain your drainage system.
