I just moved to the country and am on an aging septic that needs some love and attention. I thought this would be a great help. It IS a good idea but is too much work to be a practical benefit. It catches the lint just fine, but the trap also fills up with each load with means you have to pull out the water discharge hose, take the trap off, clean it out and put it back on. That's just not realistic with the amount of laundry we do.
