The cast-iron pipes must have the following average weights per lineal foot: Two inches 5 ½ pounds, 3 inches 9½ pounds, 4 inches 13 pounds, 5 inches 17 pounds, 6 inches 20 pounds, 7 inches 27 pounds, 8 inches 33½ pounds. All joints in cast-iron pipe are made with picked oakum and pure soft pig lead, well calked home. For each joint in cast-iron pipe 12 ounces of lead was specified to be used for each inch of diameter of pipe in which joint was made, and no joints were allowed to be covered or painted before being tested under water pressure. Afterwards pipes and fittings were painted three coats of lead paint. All wrought-iron pipe, plain galvanized or otherwise treated, is " standard " pipe, factory-tested to 300 pounds per square inch. Pipe to 1¼ inch diameter butt-welded, larger sizes lap-welded. All lead soil, waste, and vent pipe is drawn pipe of the best quality and of the following weights per lineal foot: One-half inch one pound, three-fourths inch 1¾ pounds, 1 inch two puonds, 1½ inches 3 ½ pounds, 2 inches 4½ pounds, 3 inches seven pounds, 4 inches eight pounds. All connections of lead and iron pipe are made by " heavy " brass ferrules of the same size as the lead pipe, threaded and screwed into the hub of the iron pipe. Fixture connections with iron pipe have short lengths of heavy lead pipe where not exposed to view. There are no safes under any of the fixtures. When the work was completed ready to set the fixtures, the soil, waste, and drain pipes were tested by water pressure maintained without leakage, from the level of the main house trap to the top of the highest pipe, and after the entire completion of the work it was subjected to the peppermint test.

The number and location of fixtures is as shown in the accompanying table:
