Pride Plumbing was called out for a floor drain stoppage in the chase between two cell blocks. We first attempted to use a sewer machine down the floor drain, but it would not go through. So, we then went into the drain access area and removed a 3-inch piece of cast iron drain piping, ran the sewer machine down into it, and cleared the stoppage (it was caused by a plastic bag). Then we used two new 3-inch no-hub couplings to reconnect the two sections of cast iron piping. We tested the floor drain and it drained as it should. There was also a clogged shower drain inside another cell, and we ran our sewer machine down into it and cleared its blockage.
