Hi,
I have a Hayward Tristar 2HP dual speed pump attached to a 17000 gallon in-ground pool.
My pump is making a ringing noise. I have recorded the sound in the attached MP3 inside this ZIP file:

This is my third pump motor. It has been replaced under warranty three times for the same sound. The first motor lasted about 2.5 years. The second about 1 month, and the third about 3 months now. The ringing attached is actually from my second pump, the existing pump motor is just starting to make the noise (it is too faint to capture). It gets louder over time and will eventually be as loud as the recording if ti follows the same path as the first two motors. My pool is well maintained and chemicals are in spec. It is not leaking, and it has not run dry. No event has occurred that would explain this. I was hoping someone on this forum would recognize the sound. The wet side of the pump was never replaced. Could it be an impeller shaft or something? It doesn't make sense that replacing the motor would fix it if that were the case.
