We have had a clog in one of our bathroom sinks for the past few weeks. I guess you could call it a "slow drain," where the basin fills up fast and takes a long time to drain out. My wife checked the trap, which was clear, and we'd tried all the traditional chemicals, to no avail. This weekend I found a better answer to our drain troubles, and it doesn't have any chemicals to dump into the water supply.
The product is called a Zip-It, by Cobra, (it costs $3 at Lowes!) and it's basically a 16" plastic strip with a bunch of teeth on it. You stick the Zip It down the drain, and slowly pull it back up. I pulled up enough hair and other gunk to make me think I had lost a hamster down there at some point. I used the Zip It to clean out all the drains in the house, and then tossed it. It's disposable! Consider this product Mike V approved!
I am not the most handy person around, as my wife can attest. My greatest accomplishment as a homeowner was installing some dimmer switches without burning the house down. Of course my lowest point was falling through ceiling, from the attic. So any easy household tool that can make me a hero is a very valuable find, indeed.
