The pump is not that strong, it can only push about a foot above the water. Most UV's I've seen are not watertight as it would have to be underwater with the pump.
Edit: this is what I have http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=47117
It says up to 6 feet but I haven't seen it do it.
