Even easier is just getting a super long tube for your gravel vac and run the water out of a window. I have a 25 foot tube that works great. No buckets to dump or spill. I just get a little water in the tube then go outside and hemp get the water flowing by lifting the tubing up over my head and doing that till I'm at the end of the tube.
I would NEVER put my mouth on that thing! NASTY!!!
