Leak in kitchen after using "balloon bag" to clear line
Posted by Eric on June 12, 2002 at 03:12:34:

My kitchen sink backed up so I decided to clear the line. I disassembled and cleaned the P-trap and then hooked up a "balloon bag" (a device that connects to a garden hose and squirts out high pressure water) to my garden hose to clean out my main sewer line. I fed the hose down the sewer line as far as possible and then turned the water on. Every thing was fine for the first 10 minutes but then I noticed water seeping in from underneath the cabinets. I quickly turned the water off and when I came back I also found water in the adjoining hallway.

What happened?? Could the pressure of the water coming out of the balloon bag damage the sewer line? (BTW, the house is 50 years old with a concrete foundation). Is this a 'slab leak'? What should I expect when a plumber comes to fix it (i.e. so that I don't get cheated)

Thanks for all replies.
