I was pleasantly surprised that there were no shipping or handling costs associated with my purchase and that the time between order and delivery was so short (four days including the weekend).
The new pump motor already had a mating power connector installed. All of the dimensions, mounting hardware and interconnections were exactly the same as the original resulting in a very quick replacement time.
The new pump functions so well that I suspect that the original one has been deteriorating over several years as it has been at least that long since it worked as well as its replacement.
