THE
AFFORDABLE PROFESSIONAL DRAIN CLEANING MACHINE
Never use
more than 4' or 5' of cable to clean a toilet or urinal line.
The cable must snake around two hairpin corners in the commode
or urinal and thus retracting it is difficult. In addition,
the toilet always connects to the main 4" line no more
than a few feet from the commode itself. The cable can easily
knot-up in the 4" line and become impossible to retract
through the toilet.
