We recently had a pump fail on our 3 year old Spa and had the service people from the store we bought it from install a new one. The new pump was not working properly almost immediately. The service people came back 4 times and said the problem was fixed, it wasn't. I called Scott at SOS and he asked me to describe the problem and he diagnosed it over the phone and came the next day. His diagnosis was correct and he fixed it in five minutes. Scott is very professional, courteous and honest. we will be hiring him to do all of our pool and spa maintenance.
