Identifying the Source of a Water Leak into Garage

I have a water leak into my garage from above. There are two bathrooms and a washer and dryer above the garage. I cannot figure out where the leak is originating from. Any ideas on how to pin point its origin?

Turn off the water supply to both bathrooms and all appliances. Turn one back on and check to see if any leak is apparent. Do this with each bathroom and appliance until the leak is detected. It will take time but you should be able to isolate the source of the leak. You can also do this in reverse order, turning off each bathroom or appliance. When the drip stops, the source was the last appliance.

The other alternative is to call a plumber. Costly!

It might be condensation from the cool pipes and warm air. Does it happen in the winter or just the summer?

Add some food coloring to one of the sources at a time and you'll know where the problem is.
