My plumbing skills are terrible. A ten minute job takes me three hours. So I'm pretty ignorant.

But what do plumbers use cord for?


Are you speaking about packing? It's like cord, usually square in cross-section. You can put packing cord into valves and joints to make them watertight or close to it.
