配管: water pipes and plumbing beneath the floor
Identify 配管 as piping in two examples: replacing old water pipes and water leaking from plumbing beneath the floor. Connect the English names with the object replaced and the source of the leak.
配管 names the piping
配管, read はいかん, names piping or plumbing. 「古くなった水道の配管を交換した。」 says the old water pipes were replaced. 水道の配管 is the object of 交換した.
「床下の配管から水が漏れていた。」 says water was leaking from plumbing beneath the floor. 配管 again names the plumbing, while 漏れていた describes the ongoing leak in the past.
The objects called water pipes and plumbing
In the first example, 配管 is translated as old water pipes. 水道の connects the piping with the water supply, and the sentence identifies the old piping as what was replaced.
In the second example, 配管 is translated as plumbing. 床下の locates it beneath the floor, and 配管から marks that plumbing as the source of the water. Distinguish its location from the source of the leak.
Attach the location and action to the named object
The two English expressions identify 配管 as water pipes and plumbing in their respective examples. One instance is the object of replacement; the other is the source from which water was leaking.
Placement beneath the floor is a fact of the second example, not an essential location for all piping. The focus is identifying the piping and its role. Neither sentence describes every cause of leakage or a specific repair method.
What does 配管 name when translated as old water pipes and plumbing, and what source does 床下の配管から identify?
Show the answer and why
It names the old water pipes replaced in the first example and plumbing beneath the floor in the second. 床下の配管から identifies the plumbing as the source of the leak, rather than the floor itself.
