Clearing a clogged sink

I've been plagued with a slow draining bathroom sink for the past week. I borrowed my buddy's drain snake but that didn't help. I replaced the trap and the pipe extending from the drain to the wall. I used the plunger repeatedly. It tried Roto-Rooter's drain cleaning formula. I tried Roebic Bacterial Drain and Trap Cleaner. Nothing has worked. So I broke down and bought some professional strength Liquid Plumr Gel. Upon reading the bottle, I discovered that Liquid Plumr is a Drano product. What do you know?

Despite the horror stories about Drano/Liquid Plumr destroying pipes, I poured it down my drain. Having just replaced my trap and extension, I'm not too worried about those being eaten away. What most people don't understand is that the pipes they can see under the sink are pretty fragile especially if they've aged a decade or more. They are probably the width of aluminum foil so it won't take much to eat through them. Of course, all plummers will warn you never to use the stuff again; otherwise, they couldn't charge you $95 just to show up and then another $100-$200 to fix your clogged drain.

Well it's been 45 minutes since I applied the Liquid Plumr. What will happen?

It took about an hour but Liquid Plumr to the rescue. Drain is flowing freely again. Pipes survived. Life is normal. It's amazing how the little things can make such a difference.
