Internal cleaning system for water pipes, includes stainless steel rod and casing, introduced with hot biological cleaner and limescale remover

摘要

An assembly has a removable chillum (2) (sic; the chillum is literally the part of a hookah holding the tobacco, or other substance) with head (3) and a stainless steel rod (4). The lower end of the rod carries a stainless steel casing (5) with a buffer (6) made of foam rubber or other water resistant material. The rod is introduced into the pipe, whilst it is filled with hot water, whilst adding a biological cleaner (8) and if necessary an anti-limescale concentrate (9). At the lower end of the stainless steel casing, a plastic end cap (7) protects the pipe from damage.
