Ummmmmmmm - I ALWAYS have a nylon/pantyhose leg over the washer hose end to catch ALL my laundry lint/fibers. Helps to keep the pipes unclogged (whether you have city or septic pipes). I've been doing it FOREVER.
Try it! Change the nylon when it starts to fill up like a balloon when the washer empties...you don't want it to 'explode'
