We have a Kenmore side by side refridge with ice & water in the door that uses the 46_9010 filter. We have had Sears out twice in the last 9 months due to stringy stuff floating in our water from the door. We tried replacing the filter but that didn't help. The first time the repair guy finally replaced the storage tube in the ref. and that helped for about 8 months. It is doing it again and Sears came out and the repair guy said that it was due to the high efficiency of the filter taking out the clorine in the water and that was allowing bateria to grow in the storage tube. He claimed that if we disconnected the filter and allowed the water to run through for a while it would eventually clear up. I would like to know if this is a true statement that the filter is so efficient that it allows bateria to grow in the storage tube or are we being told this because they don't know what is causing the problem.
