POOL SKIMMERS 101: How To UNCLOG Your Pool Skimmer Line | Swim University

Your skimmer is your first line of defense when it comes to filtering out debris in your pool. And that means it’s easy to get a clogged-up skimmer line. So if you’re getting poor suction or you think your pool skimmer line is clogged, there are two ways to unclog your system: 1) Move the pool diverter valve (or Jandy valve) back and forth to open and close the skimmer valve; 2) Clear the blockage with a drain cleaning bladder like a Drain King. Before you troubleshoot, make sure it's indeed a clog in your skimmer line and not an air leak in your pump.
