Pooler12345 Posted December 8, 2016 Report Share Posted December 8, 2016 Hello, New to the forum I am helping my neighbor determine a noise issue with his pump (as the pump borders our fence)... he had his pool redone and they installed a new 1.5HP Hayward (I think its a Hayward Super pump II) and out of the box its makes a constant whirl sound (not a screeching bearing sound)... I read that these pumps have an internal cooling fan.. Hayward's own installation manual says to not mount these near a window due to the fan noise...When the pump first turns on and water begins to flow the motor sounds very quiet.. after about 15 seconds I hear the whirl (its constant - almost sounds like a turbine from distant power plant (for lack of a better description)). I assume at startup there is no load, when water is fully flowing the motor is under full load and the whirl sound starts. . is this sound typical for these pumps?...does this sound like the internal cooling fan?... is it load related? ... is it normal? ....any feedback would be appreciated thx Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted December 23, 2016 Report Share Posted December 23, 2016 Is it a super pump VS? It may be a speed issue causing this. When it starts, it may be going into a "priming" mode where the speed ramps up for a period of time Usually 30 sec or so then settles down to a slower speed, or visa versa. If he can adjust the "run" speed, try that first. If it isn't a VS try moving the pump. Not actually moving, but put your hand on the plumbing or the motor to stop a possible vibration related noise (i know you stated a whirl noise, not a vibration). If a single speed pump and not a vibration issue, perhaps a call to tech support may give some ideas. Quote Link to comment Share on other sites More sharing options...
Keith Toal Posted April 19, 2021 Report Share Posted April 19, 2021 I have a new pool with a Hayward and it is ridiculously loud compared to my last pool. It is a fan noise and not cavitation or impeller noise. Disappointing! Quote Link to comment Share on other sites More sharing options...
