So I'm brand new to pools and just bought a house with a pool. I am trying my best to maintain it but sometimes the skimmer diverter stops allowing water to come through the skimmer. I have it set with the bottom almost completly open and initially it works. After a few hours I've been going back outside and no water is coming through the skimmer. I have to remove the diverter and play around with it for water to start coming through the skimmer.. Anyone know why this might be happening? Do I have to have the diverter on? There are two holes underneath the diverter if that means anything. Thanks!
