Pride Plumbing was called out for a water leak in a breakroom ceiling. After gaining access into the ceiling, we found that a cast iron drain line had cracked and was causing the leak. We cut out the cracked section of pipe and repaired it with new PVC piping and fittings; connecting onto the existing cast iron piping with new no-hub and Fernco couplings. While testing the kitchen sink's drain line, it backed up with water. We removed the sink’s P-trap and used a sewer machine down through the sink's drain line and cleared the blockage. After replacing the P-trap and testing for leaks and proper drainage, the issue was corrected. We ran hot water down the sink for several minutes and it drained properly.
