There are two types of unloader valves: the pressure-actuated unloader and the flow-actuated unloader. The pressure-actuated unloader works by responding to increases and decreases in water pressure. The flow-actuated unloader relies completely on water flow; a halt in water flow increases the internal pressure. Most unloaders are designed to function with 5 to 10 percent of water flow in the bypass at all times.
It is a popular misconception that 900 followers of cult leader Jim Jones. committed suicide by drinking Grape Kool-Aid laced with cyanide at their. commune in Jonestown Guyana in the late 1970's. This is not true. The. followers of Jones actually drank cyanide laced Flavor-aid, a cheap. imitation of Kool-Aid.
That's right, back then, in 1978, I was working for the late and lamented Los Angeles Herald Examiner and I was assigned the Jim Jones case, yep, the man who lured 900 followers to their deaths in Guyana because they did drink the Kool-Aid. That concoction was laced with cyanide.
