Combination stop-and-waste valves and cocks shall be installed in an underground potable water pipe. Frost-free hydrants and fire hydrants shall not be considered stop-and-waste valves.

True
False

The correct answer is: False

The statement is false because frost-free hydrants and fire hydrants are indeed considered stop-and-waste valves in the context of plumbing systems. A combination stop-and-waste valve is designed to allow for the drainage of the line when it is not in use, effectively preventing the water from freezing in cold conditions. Frost-free hydrants serve this purpose by allowing water to drain below the frost line, preventing freezing. Similarly, fire hydrants function in a manner that can help to drain the system as well. Since both types of hydrants are capable of providing stop-and-waste functionality, they should not be excluded from this category. Thus, the assertion that they are not considered stop-and-waste valves is incorrect.
