Question

question 10 cross connections may exist at each of the following except supply faucets below the flood rims of fixtures drain connections from dishwashers water softeners outside hose bibbs with no hoses attached lawn sprinkler systems

Explanation:

1. For sump pumps: They often operate on 115 - volt or 230 - volt power, can be pedestal or submersible types, and should have a hermetically sealed lid to prevent odors and pests. A check - valve in the discharge pipe is common to prevent back - flow, and they can be automatic or manual. So the correct statement about sump pumps here is that they may be pedestal type or submersible.
2. For cross - connections: Cross - connections are potential paths for contaminants to enter the potable water supply. Supply faucets below the flood rims of fixtures, drain connections from dishwashers, water softeners, and lawn sprinkler systems can all create cross - connections. Outside hose bibbs with no hoses attached do not typically create cross - connections as there is no pathway for non - potable water to enter the potable water system.

Answer:

1. may be pedestal type or submersible
2. outside hose bibbs with no hoses attached
