I ran into two cases in two days at two different restaurants where some schmucks poured their excess concrete floor patch down floor drains. Both drains are 4" cast iron, I was able to break up the stuff in the bottom of the trap, but I wasn't able to dig the stuff out of the horizontal part. I have 1-1/4" open wind cables for my machine. Can they get thru a trap and the concrete? Or can muriatic acid dissolve the stuff?
