Any troubleshootin suggestions? I recently bought a simple barrel fountain with a Pondmaster 140gph pump. It was working fine for about a week. Now on 3 separate occassions I find the barrel with only about 2 inches of water left at the bottom. I checked the barrel liner for a leak - none. I'm baffeled what's causing the water to disappear so fast. I thought maybe it was an animal, but this evening it happened in only a few hours from when I was last on my patio where it was fine.
