Probably a simple question here - I inherited a pool when I bought my house 3 years ago. Old pool. No skimmer equalizer under either skimmer basket, which explains why there's no suction from the main intake at the bottom of the pool. In a previous thread someone told me I needed the Pentair #85015200 assembly which I now have (2 of them).
How do I adjust the "flap" on the bottom to get the right mix of draw from the skimmers and the bottom? Pic below (not of my model, but same concept).skimmer assembly.jpg
