Well folks, the garbage disposal is installed and working. A slight leaking problem at first, but nothing that the tightening of a few plumbing parts fixed in a snap.
There was a little more to it than I expected with hooking up the electrical wire to the unit itself. And yes, Andy and FM, it was a task trying to get the old one off and hoisting up the new one.
Charlie... sadly we ended up with the Kenmore brand that was reccommended by Consumer Reports... I am not a fan of Kenmore products and had my reservations about it, but hubby assured me it was the way to go... we will see!
Thanks for all the replies, I get more confidence each time I accomplish the handy man tasks around the house.
Just for grins, anyone have any idea what they charge you to have it professionally installed???
