I got into a debate on another fourm about using hand snake's for drain line's 2" and under. Needless to say there was a few angry blogger's who disagreed. When I refer to a hand snake for drain's I simply am talking lav's,bt's, ks's and Lt's. Most of the time the drain can be unclogged without even taking off the trap. This is a method I learned and for me work's well. I only pull out the machine when all else has failed. Is my method so wrong?
