William Gaines, the creator of Mad magazine, was born on this day. And "mad" is what folks become when a drain gets clogged. When it's no-go with the flow, here's what to know, before calling in a pro. First, grab the plunger. If that doesn't work, try blasting the clog by putting a garden hose down the drain. Pack rags around the hose, and then turn it on. If it's still clogged, try a drain cleaner. Most are caustics with oxidizers that turn grease and hair into a gooey soaplike substance. Or try enzyme cleaners that eat away organic materials like food. Beyond this, either run an auger (or a snake) down the line or call in a drain specialist. Always run water for at least 30 seconds after using the garbage disposal. Be careful what you put down the drain and treat it regularly with salt, baking soda and white vinegar followed by boiling water. If you maintain your drain, like Alfred E. Neuman, you, too, can say, "What? Me worry?" And that's the On The House tip for today.
