Purchased this expensive pool pump end of April 2019 as my pool maintenance person indicated this expensive variable speed pump would be much more efficient and save me money versus the pump I had for more than 10 years. Supposedly it was the top of the line. Now I am told it is no longer working after just 15-16 months after it was installed. He is also telling me it is no longer under warranty. This product is either a very low quality pool pump or I received a lemon which should be replaced. User's recommendation: Do not recommend product.
