Baby mama skipped out on me so I moved a new tenant in.  2 days later, the new tenant called and said that sewage was backing up into their unit.  The first two sewer cleaning companies couldn't fix the problem but they could diagnose it- turns out baby mama flushed so many baby wipes down the toilet that the last 10 feet of the lateral was packed with them.  It took a diesel engine powered water jet an hour to get the blockage free.  The pics didn't turn out well but you get an idea of what took place.  The only thing not pictured is me whimpering writing out a check for this service.
