Makes sense to me. Luckily, I'm the one home all day and the majority of the time it has been set to filter.
Still, the backwash issue remains. Any ideas of why the system is dumping pool water instead of the dirty water inside the tank? I think this issue has nothing to do with the vacuuming I did - my husband and I both agree that we've never seen dirty water come out of that hose. Could the sand possibly be so calcified on the bottom that the water just isn't getting out? The sand on the top that I reached down in and grabbed seemed to be free-flowing and ok.
