Question

which of the following is least likely to have a cross connection? outside hose bibb bidet shower stall water softener connection extendable faucet at the kitchen sink question 17 entrances into shower stalls should be a minimum of 16 inches wide 8 inches wide 20 inches wide 22 inches wide 28 inches wide

Explanation:

A cross - connection is a connection between a potable water system and a non - potable or potentially contaminated system. A shower stall is a self - contained fixture with water flowing in one direction from the supply to the drain and has less potential for backflow or cross - connection compared to other options like hose bibbs (which can be connected to hoses that may be used in non - potable water sources), bidets, water softener connections (which can have backflow issues), and extendable faucets at the kitchen sink (which may be used in ways that could introduce contaminants). For the second question, building codes and accessibility standards typically require shower stall entrances to be wide enough for people to enter comfortably. A minimum width of 22 inches is a common standard to allow for ease of access, especially for those with mobility aids or for general comfort.

Answer:

1. C. shower stall
2. D. 22 inches wide
