Grech CHJ-4500 1188 GPH Aquarium Submersible Fountain Pump

This thing does move water, though I haven't measured to see if it actually goes 4500l/mIt comes with a bunch of different sized fittings and some suction cups and fastening flanges, which is nice.I have noticed that sometimes when I turn it on, it does not pump. Instead it just buzzes - the impeller does not spin. Smacking it around a little sometimes helps to get it going.

Pump works however they claimed it could lift water to 3.5 meters and it did not. Moves water fine on the level but would not raise it ten feet up which is what I needed.

Great pump but box was crushed.

I have issue now ,pump failed. Now my aquarium sump is not being used. I have a back up pump, but it's weak. I hope they make it right.

Functions as advertised. Able to have enough head pressure to push water upstairs and 25 feet.
