You are off your head, mate, and clearly either deluded or on a wind up. Your infantile observations above hold no merit, as a few moments of analysis would reveal.
I was not referring to DIYers time, but to your idiotic suggestion that a pro should resort to stick pushing rather than utilise their years of experience.
And, pray, how does one get the stick in without cutting the pipe? And how does a DIYer determine what pipe to cut to insert the said stick?
How long and flexible is YOUR stick?
