The time has come for me to replace my mesh wheel on my SWC 160 cone skimmer. My pump stalls anytime the power is cut. I simply blow into the airline and the skimmer starts. I ordered a pinwheel for the Atman PH2500 that I found on ebay. It makes a horrible buzzing sound when the airline is open on the skimmer. With the old mesh wheel it is dead silent. I'm just trying to fix the stalling problem. I have read a few posts where people installed a washer. I tried some random plastic washer i had laying around and same problem. If anyone knows where to get a new pinwheel that WORKS for this skimmer or has another fix please help. Thanks in advance.
