After 20 years of great service, my Zodiac Baracuda was beyond repair. Price wise I decided for the Xtremepower (~$90) versus a new Baracuda (~$250). For the most part, after 3 years, I cannot complain about the device. Had some issues that I fixed (worn out slots for the flap - corrected with zip tie, tee assembly broke gasket - replaced $20.00). The problem that I currently have is that when the pump starts, the vacuum does not start cranking. I have to give a little pull to the hose and it starts without a problem. The flap is free and moves up and down. No obstructions on the hoses. Try different levels of suction (at the skimmer intake - have a regulator) and the intake valve at the pump. No clue what can be causing this. Any suggestions? Thanks
