Our florida inground pool is just finished, and the 1.5 hp Sta-rite Max-e-pro pump on a concrete pad is running fine. But it has a annoying pulsating beep, that, while not very loud, is quite noticable, perhaps 3 or 4 beeps per second. Standing at certain angles from the pump, you cannot even hear it. Is this normal? Installer has warned us that it will be difficult to make a warranty claim because the pump is basically working ok. Because it's agasinst our bedroom wall, it is very annoying when pump runs at night. Anybody else have this experience? Ideas?
