Proper Tool Selection
A good rule of thumb is to make the first pass with either
a spear cutter or blade cutter that is 2
″
smaller than the
drain size. For additional passes, larger tools may be
used. However, tools should always be at least 1
″
smaller
than the drain size.
The style of the tool is determined by the nature of the job
and is left to the discretion of the operator.
Flexible leaders should be used to negotiate bends and
traps in lines.
