A systematic shop inspection must be given to each pump to ensure
completed workmanship, and to prevent the use of defective parts,
improper materials, or the careless leaving of foreign matter in any
part of the cylinders or chests.
Several instances have occurred in which chisels, bolts, or core
irons have been found in steam chests or steam cylinders. This
has resulted in a serious crippling of the pump and in some cases
requiring repairs to be made before the pump could be used for fire
purposes.
