The barracuda is a low speed pump and it spins at 1450rpm, the mag drives spin at twice that rate so they are noisier, more power hungry and they generate more heat. The barracuda in the basement would normally be silent and if we cannot torubleshoot the problem then it will be replaced by our UK dealer, that is our policy...you paid for a quiet pump and you will get one. Noise can be caused by cavitation where the discharge capacity is greater than the intake capacity (half a breath in, full breath out)...if you branch out immediately after the discharge, this could be it...closing down a valve on the dicharge line would be a check for this. The other possiblilty is a loose fan making contact with the fan cover (transporters love to cause this) and the most common problem is shells and other debris gettiing caugth in the pump housing...the pump cover is easily removed to check this....the last cause cannot be fixed...that would be bad bearings...although we test all pumps on the assembly line, the aforementioned transporter can jolt the pumps enuf to throw the bearings out of alignment leading to premature wear. This would sound like metal grinding form the middle of the motor.
