You can pressurise your sewer cleaning machine or sewer combi yourself via the pressure regulator. The number of litres per minute can be set via the engine throttle. More throttle will deliver more litres per minute and less will reduce the litres delivered.
Do you want to clean and remove dirt? Then set a low pressure with a high number of litres per minute. This will give the best result for flushing the debris from the drain pipe. Is there hard material, such as grease, cement or scale, stuck in the drain pipe? Then turn up the pressure to force the material to loosen.
If you want to solve a problem as quickly as possible and achieve the best result, you need a spray nozzle to rapidly resolve the problem professionally. But which spray nozzle do you need and when? An explanation is provided for each problem below.
Nozzles can be divided into 4 types: standard spray nozzles, rotary spray nozzles, chain scrapers/cutters and industrial spray nozzles.
