102. WILL NOT
Always BE EASY
• Full investigation of the inspection
site, is not an easy or quick
procedure.
• Full disclosure takes time and
patience.
• Called to pump a tank-stoppage.
• Video locate on the roof.
• Found a stoppage.
• Called a plumber
• He removed the blockage.
• Put the camera down the roof vent
again.
• Feed went to a break at intercept of
home delivery and municipal sewer.
• The home had been connected to
municipal sewer for years and city
had no record of it.
• City wanted proof that home was
connected to their main sewer.
• Proof was a Dye Test.
