I have a small drip that seems to be getting worse from the top of my sand filter valve. At first I thought it might be the spider gasket, however, I have seen that it might be a small o-ring at the top (#5). Anyone want to guess the part that is the problem and are there any other parts I should switch out while I have it open?
How about the reassembly? I have a feeling that the spring is going to be a bear to wrestle back in place.
