Shasta came the day after our call was made. They said someone would call between 7-9 to let us know when a technician would arrive. We receive a call just after 7. The technician arrived exactly when we were told he would. He found the problem immediately and fixed it. He also checked a couple of other things for good measure. This is my second Shasta pool and I would never have any other brand. They stand behind their warranty and they have excellent customer service. Thank you.
