In my particular case, I had to separate from the container and because of the pump local conditions juxtaposing. With some craftsmanship me this is well managed. Then I plugged in and started the pump. And I had some initial difficulties because obviously somewhere in the system had formed a bubble. But the pump at one time worked flawlessly. Since then the work if 15 years or running properly, I would hope, would like to keep the previous model. Until now, in any case recommendable.
