The installation was done quickly and without any incidents at all. The system was installed correctly and was as expected. The pool has stayed at the desired 80 degrees throughout the season. We swam comfortably through the end of October last year, and drained it after some heavy rains cooled things down. If we had not done so, we probably could have used the pool through Thanksgiving. It was ready by mid-April, after an abnormally cold and wet spring. In normal years, I expect it would have been useable earlier. We have sprung some minor leaks, but they were repaired within a day of notification.
