yeah, im currently trying a sulfuric acid based industrial drain clog remover. if this doesnt work, ill be calling the landlord and letting him know the sewer line outside is plugged and causing wastewater to back up into the stationary tub. im pretty sure its a mass amount of lint, when we moved in there was no lint trap on the laundry line to the tub, and ours must have been missing the past week or so cause it was gone too. must have been full/thrown out by the roomate…pray this works. the landlord doesnt know we have cats and a third roomate. grrrr
