EBOOK - Home Guide to Plumbing, Heating and Air Conditioning (George Daniels)

WE HAVEN'T had our modern plumbing, our automatic heating, and our air conditioning very long, and considering the obstacles that have impeded their
development over the years, it's a wonder we have them at all. England, for
example, once rated the burning of coal as a capital offense, and at least one
Britisher was executed for the crime. So it's understandable that heating innovators  may have become a bit timid.


In France, advances in cooling rather than heating were blocked by the government. When 16th century Frenchmen built a thriving business by carting tons of snow and ice from the mountains to chill their summer foods and make frozen delicacies, they might soon have progressed to air conditioning by the same means. But the icemen's taxes were boosted until the business collapsed, and artificial cooling was forgotten for another hundred years. (More about the rigorous past of heating and cooling shortly.)
Plumbing, on the other hand,  made slow headway largely because our ancestors of long ago rarely took much interest in it. If they had they might have copied an almost incredible example 4,000 years ago. At that time, archaeologists now know, the plumbing in the Cretan palace of King Minos was so advanced it incorporated the most important features found in our plumbing codes today.
Its sewerage system, for instance, was vented as required by modern health regulations. Its toilets not only could be Hushed, but, like all present-day plumbing fixtures, were designed to seal out sewer gases. And, for a final master's touch, the terra cotta water-supply pipes w'ere tapered to  increase the How velocity at points where sediment might otherwise accumulate. But,  along with the ancient culture that created them, all these things and their related ideas of sanitation, vanished. If they had not, many of the great plagues of history might never have occurred; and, in addition to the name of King Minos, history might have recorded the name of his plumber.
Though hygienic refinements faltered and progress was slow, the watersupply spects  of plumbing eventually revived on a major scale. What was probably the first  long-distance municipal water system was developed for Jerusalem by King Hezekiah in 727 B.C. To do it, he had his workmen tunnel a third of a mile through rocky hills to bring water from the Pool of Siloam to the city. The finished job worked beautifully.
