Which of the following is a house construction and design trend that has affected hot water delivery?
  1. Larger houses mean longer travel distance from water heater to farthest fixtures
  2. Greater number of plumbing-related fixtures on average
  3. More fixtures served by the trunk line
  4. All of the above
Explanation
Answer: D - All of these trends have affected the delivery of hot water in a home. Longer distances for hot water to travel mean more unused water waiting for it to heat up. The increase in the number of plumbing-related fixtures has led to more hot water use, under simultaneous conditions at times. The increased reliance on the trunk line necessitates changes in pipe diameters.
