Shasta installed a new multi-speed pump on our pool system as required by AZ law in replacement of the previous 3HP single speed motor. Although I preferred the old pump, I am looking forward to saving some money on my monthly electric bill going forward with the new pump. It is definitely quieter than the old model. The Shasta tech spent the time necessary to make sure that I was proficient in how the new pump is programmed and operates so that I can make adjustments as necessary. Shasta has always gone the extra mile to ensure that we are ultimately satisfied with our product.
