Pipe Inspection

I spotted a loose cabinet door beneath the kitchen sink and squeezed right inside. Towering right above me was a massive, curving metal pipe! A real plumber never ignores good piping. I dragged over two yellow cleaning sponges, hopped on top, and gave the curved elbow joint a sharp tap with my glove. Clank! Solid, sturdy, and no drips anywhere. Everything sounds clear down here!
