If the suction main for a pump is underground it shouldbe made of cast iron and if it is subject to vibration, set-tlement of ground or excessive expansion strains it shouldbe flanged and have metal gaskets. The most satisfactoryarrangement for long underground suction connections is tolocate the underground piping at a level below the waterinlet or water surface and build the lift pipe so that it isexposed free to expand and opportunity is afforded for readilymaking repairs.

Figure 214-(F1-1) will illustrate the detailsof a very satisfactory arrangement of piping for such well should be about 3 feet in diameter, have aladder inside and a man-hole top covering so arranged thatthe suction pipe will be supported from above. If the water-line, a, to the well is large, about 24 or 30 inches in diam-eter, it may be built of clay sewer pipe with cementedjoints which will prevent any leakage of sand. The con-.
