Review on Aqua Dream Submersible Pump: Ultra Quiet Water Pump for Pond, Aquarium, Fish Tank, Fountain & More! by Vanessa Szymanski

The pump has good volume, is quiet and comes with a range of accessories that made my installation easier. The only downside is a very small leak on the discharge side of the pump. It drips about every 40 seconds. Since I installed it outside, it's manageable for me, but it's a bit disappointing. I didn't screw it on but flexible hoses go to the pump so there was no pressure on the fittings. It just is. One star deducted for that. The vacuum side is sealed with no air leaks, which is most important as it easily loses its effectiveness if you place it above the waterline and air gets into the line. Update: I'm a week in and the little leak has stopped. I have also found that if you mount it face down the front impeller hub will be pulled towards the shaft and water flow will be greatly reduced in a short period of time. I recommend installing with the suction port of the pump horizontal to the floor. I also opened it up (by rotating the impeller cover) and inspected the shaft to make sure the bushings were installed properly and the retaining clips were holding the shaft properly in place. I believe this review also resulted in the seal being reset, stopping the aforementioned leak. The rectangular fitting fell apart during work when I was tightening it to the impeller shell, so I wouldn't trust that. It appears to be a design issue with the fitting itself. I used a straight fitting which is designed differently and will have no problem. Had to use flexible hose instead of elbow for my plumbing. Now I have no leaks and the water flow is even better. Another star down for the lack of good installation instructions for this important consideration. I recommend the device once you have read my review and you are ready.
