Understanding and Evaluating Presidents. Theodore Roosevelt changed the publicâs perception of the presidency by asserting the centrality of the office in American government. The president is chosen by the whole nation, not just a district or state, and therefore the office of the president is the most important office in the federal government.
Washer pits and boxes vary in size and shape, but a standard for one-hole washers is 16 in Ã 16 in Ã 4 in, with a cylindrically-shaped cup (4Â½ inches in diameter and 5 inches in height) located in its upper surface.
Bar sinks typically use the standard 3 1/4-inch drain size like a kitchen sink. They also use 1 1/2-inch drainpipes and P-traps. A laundry sink drain is 1 1/2 inches in diameter and uses a 1 1/2-inch drainpipe and P-trap. A whirlpool tub uses a 1 1/2-inch drain with the same size drainpipe and P-trap. Other drains follow similar dimensions. Drain sizes are usually chosen based on how much volume of drainage is needed.
