Nothing boat related. This is more light duty construction related. I want to fill a bladder with air for light duty (100-200 lbs) lifting, then dump the air to deflate the bladder. I need to be able to do this easily without bending over or using any other tools to deflate. I think a valve used to drain compressors would work, coupled to a ball valve, but I am wondering if there is some sort of valve that would fill, then deflate.
Thanks for any input.
