Hi, newbie pool owner here and need your help, please. I'm trying to figure out the rattling noise I'm hearing that sounds like it's coming from the main pipe that goes from the skimmer to the pump. I accidentally left out the skimmer basket after vacuuming the pool a week ago and didn't notice until I started hearing the rattling noise last night. When I look at the pump strainer, the water appears to be flowing as normal but it's just the rattling noise that's new. Did I break/ruin my pool filter? Any suggestions how I can isolate the problem and fix it myself? Your help is greatly appreciated. Thanks!
