On TV, when Jackie Gleason wanted to know about sewers he asked Norton. But we find out only when pipes start backing up. And as if water damage and sewage aren't bad enough, you could be in for another surprise. Many times homeowners are responsible for fixing sewer lines well beyond their property, all the way to the city's main line, sometimes hundreds of feet away.

You might be tearing up walks and driveways, shrubs and lawns and paying to redo city streets, too. There is a solution. Call for a video sewer inspection. A small TV camera is run through sewer lines, showing everything on a TV monitor -- to catch and fix trouble early. If you're buying a home or just want to avoid costly problems down the line, consider putting your sewer on TV to see what's up -- or down. And that's the On The House tip for today.
