Check with the landlord BEFORE ordering. Weight - specs do not indicate how much water is needed - or potential leakage may be issues for some owners.
Also, if another tenant does not like the "noise" it makes, the fountain will most likely then have to be removed. That may sound ridiculous, but I once lived in a building that had a NO WIND CHIMES policy because one tenant complained, so all such chimes had to be removed from balconies and patios. (I didn't have a set, but the sounds didn't bother me either.)
