Vibrations for a Waterbag

[zacsol]

Does anyone have a water-bag setup? I have one (100 lbs) beside a long 6' bag (100 lbs of cloth filled) and another shorter heavy bag (80-100 lbs of sand/cloth filled). Only the water bag has a crazy amount of vibrations that go up into the ceiling and shakes the kitchen above? Should I use springs or anything else to help with that?

Thanks!
