When you have standing water that has to be "shipped," it is usually urgent to alleviate the situation - it is a distress. If you put a pump leader down into the water and start the reciprocating valve, the boot will draw no pressure because the air involved expands and contracts, as well as flowing freely around the otherwise permissible allowance that tolerates movement at all. To gain purchase for mechanical advantage, it is necessary and proper to pour water from a preexisting supply to fill the line; once vacuum occurs (when the pump attempts to draw,) more water flows than was invested and the distress of people, having a standing lake or a displaced pool, can be answered.
The reason of our common warning is that the principle of pumping (like all else) can be abused. Even a spring fed well can only fill at a finite rate, and pumps are made to reliably exceed this, or they would be archeological oddities. When a friend or stranger offers up, "He's just priming the pump," he certifies an opinion that the operator - so far from being an incompetent charlatan - is a threat to reasonable usage, and has a slash and burn intention toward the resource.
Warnings are epidemic in American Society since the litigious 80s. The only advantage to be had from the cacophony of alarms is to turn them upon adversaries and use them as _characterizations_. They are unnecessary so often that the cry of "Fire" in a BURNING crowded theater is likely to obtain a callous audience; we are so fatigued with warnings that hyperbole is a diet.
Sylogistically, (under these conditions,) more warnings are not in order; what IS in order is difficult to say.If we have a well primed pump, we need (procedurally,) to attend to the next priming, but on a schedule that employs such benefit as may be had from the hemorrhage. Put out a fire; irrigate a farm - don't pull the hose precipitously from the source and blow the high-turning engine unless emergency defines the situation and this answers the emergency appropriately. If there's enough water, don't neglect duty; just "don't be a _hero_!"
The pump is capable of work as advertised; what is needed is strategy to govern strong pumping tactics. My lament is that the characterization is so oft untrue that employment cannot be promised on a schedule - stories of primed pumps abusing things abound, but upon arrival the plundering fire department is always elsewhere.
As an anchor to my initial intention, I want to prime the pump for those who cannot articulate exactly what they mean by activities Unamerican.
Germans engineer, Chinese are patient to a fault. The British maintain appearances in face of all disaster and Americans innovate. To fail at innovation is not to fail to be American - it is simply to be excelled on your own turf.
To be Unamerican is harder to enumerate, and so I prime the pump. To define (I've cited before,) is to give rules that when unbroken cannot fail to answer, no matter what the appearance. Otherwise we list; I am articulate and even _I_ have trouble. My list is single thus far. I close by listing the one thing I can put my finger on.
It is Unamerican to impede illumination of truth in pursuit of Justice.
