The pump was making some strange noise last few days. Today, it suddenly stopped working after making a bang noise. 10 minutes later another screeching noise for few minutes. I switched it off. Not sure if it's the motor or the pump the problem. It is a WhisperFlo (Pentair) fixed speed 1 HP power. The pump was installed by previous house owner. I was told warranty does not transfer. It was installed in 2011 by my estimation. Moot point. Pentair has proposed either a fixed flow Superflow & WhisperFlo (DOE compliant) 1HP or a variable flow pump Intelliflo i1 & i2 with 90% energy savings. I expected to pay more for the latter. My pool guy say he can install it. He will provide some estimates tomorrow. Should i bite the bullet and go for the variable speed pump? Where should I get replacement pump (dealers, Amazon, Leslie's etc..). I am new to this and appreciate advice. Thanks.
