I was doing it all the time, so I started putting the bucket next to me on the couch, well all the sudden my foot got wet. The bucket was about 1foot away from me. Now when filling 5gal buckets they go in the kitchen sink. The worse one was when I pumped out my 55gal drum, and left the hose in it. About 2hours later one of my Apex water bugs was going off??? Well it back siphoned into the barrel, and all over the floor.
Like Greg said its a right of passage. If you havnt flooded something, you are not doing something right.LOL
