In a recent remodeling of Mr. R. P. Flower's residence, at New York, all the piping and many of the old fixtures were replaced, and a new supply, waste and ventilation system were adapted to the existing construction and its requirements. The following details show how some of the work was made to conform to the necessities encountered.

Figure 1 shows the 1,000-gallon wooden storage tank T in the attic. It is filled through the pump pipe A, or, when city pressure suffices, through the ball cock B. C and D are circulation and relief pipes from the high and low-pressure boilers. They arc both connected to the check valve E that opens with a downward current and lets steam escape, but closes with an upward current, thus preventing escape of tank water through it by syphonage. G is the house supply, with a check valve H that closes with a downward current to prevent the filling and overflowing of the tank through it when city pressure exceeds tank pressure. I is a lead safe, and J is a soil pipe carried, with the other risers, in the pipe shaft K.

Figure 2 shows the connections of the gas-engine pump A and hand pump B in the subbasement. C is the cold-water supply from city mains, with "branches D and E for the suctions to hand and gas pumps which deliver through branches G and H respectively to the 1¼-inch tank pipe F.

Valve I is usually closed, but by opening it riser F may be drained through waste pipe J into the drip sink S. K is a cold-water supply to sink, M is a 2-inch refrigerator waste, and L L, etc. are drip and safe wastes, all provided with flap valves at sink. N is a gas pipe to engine, Q is an air chamber, V is a vent pipe, O O are soil pipes, and P is main 6-inch house sewer, supported on iron hooks from cellar wall at each joint.

Figure 3 shows the arrangement, in a basement cupboard, of a Tucker grease trap T, S is a duct up to butler's pantry, C is a 2-inch waste from butler's pantry sink, A is the 1-inch supply from city mains, B is the 1-inch outlet with ½-inch branch E to butler's pantry and ¾-inch branch B to kitchen sink, F is the 2-inch waste, and G the 1½-inch vent.

Figure 4 shows the large grease trap in the sub-basement for kitchen waste, B is the 1-inch cold supply under tank pressure with branches C to trap and D to kitchen. E is the delivery with branches F to laundry, H to servants' water-closet, and G to first-floor basins, I is the 1½-inch waste from kitchen sink, and J the 1½-inch outlet to sewer K; Lis a vent pipe.

The work was executed by John Toumey & Son, of New York.
