Top seal was simple. bottom seal required a little thinking. I followed instructional online videos and was able to get the bottom seal installed.. I didn’t have to disconnect the power wires on mine. I just had to kill the breaker at the box. All good now no leaks..I did have to replace the flexible water hose because they normally leak if you take them off after they’ve been on there for several years. I expect this unit to last many years. A hundred dollar fix sure beats a thousand dollars for a new one. I went with overnight shipping which added a few bucks but its worth it to me to keep the unit operational. Parts arrived next day.
