Once we have built the fountain, it has been found that the water jet not in the provided lower container but injected next. The laid in the upper tank water pipe was installed incorrectly. In full sunlight the fountain would be empty within a short time. Then of course, the water pump is running dry and then you have indeed a beautiful fountain but since nothing moves more. After hours we made it with little tricks that the water could not flow out. Has cost us a lot of nerves. The only question is whether it would someday again bib. Maybe I've had bad luck with my copy.
