Keith P Ivoryton , CT March 03, 2017 Clogged drain tube Swapped it out for new tube. Take 5 minutes and zero effort. The drain tube will clog with mold. You can clean it out but the tube will clog again despite's you best efforts as the tube wall provide a great habitat. Ordered new tubes to facilitate swap-outs. Old tubes can be cleaned but will recolonize quickly. 15 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
