What are common signs of a leaking cold water pipe, and what is the immediate action to take?

• A. Wet spots, dampness, or running water sounds; shut off the main supply if necessary and locate the leak for repair.
• B. A drop in water meter reading; call emergency.
• C. All faucets suddenly running cold; replace water heater.
• D. The sound of birds chirping near pipe.

Answer: (A)

When a cold water pipe leaks, you’ll often see wet spots or dampness on surfaces and hear running water or dripping even when no taps are on. These signs show water is escaping the pipe. Because a leak can waste a lot of water and cause damage quickly, the immediate step is to shut off the main water supply (or the nearest accessible shutoff) to stop the flow. Once the water is off, you can locate the leak to arrange repair, which could involve tightening a fitting, replacing a damaged section, or other fixes. If you’re unsure or the leak is severe, call a plumber. The other options don’t fit: a drop in the water meter can be from usage or meter issues, all faucets running cold points to a heater issue rather than a leak in the cold pipe, and birds chirping isn’t related to plumbing.
