Weak pump = poor flow
The pump is set at the highest output but it’s not strong enough to make the water flow properly down the tiers, let alone spin the glass ball on top. I even removed the impeller flow control piece and it made no difference. It just puts out enough water to dribble down one side. The fountain looked lovely and the lights inside add to its aesthetics, so I’m very disappointed in its performance. It also didn’t come with enough rocks. There were 10 river stones which barely covered two of the three tiers.
