Arrived at property and was greeted by front desk operator. She explained to me that the floor drain was backed up and that the owner had attempted using a drain opening chemical. Upon investigation I saw that the line was completely full of what seemed like to be a concrete slurry, mixed with cast-iron chips. The line is completely stocked up with a hard blockage where the drain machines cables unable to pass, and I’m unable to get a camera through. Attempted multiple ways of getting the line open, including with drillbit and with wire. Provided estimate for floor drain replacement.
