Moving the Ferret along the leaking pipe
3.4 Passing through a restriction
Step 1.
Locate a reference point
on the Ferret Pipe.
Step 2.
Turn the Ferret Winder in the Rewind
direction (A) to tension the Ferret Pipe and
then turn the Ferret Winder back a quarter
turn (B) to put some slack in the Ferret Pipe.
Step 3.
Slowly reduce the pressure
in the Ferret until the water
in the pipe pushes it through
the restriction. Watch the
reference point to see when
this happens.
REFERENCE
IMPORTANT:
Once the deflated Ferret
is back in the larger diameter
pipe it will stop but the
Flow Gauge will register
the water flowing past it.
