My pipes (primarily cold water) just started to moan when I turn off the water in the kitchen and bathroom sinks, not the tub. I read the previous inquiry on this, mine doesn't seem to be related to the toilet flushing. The house was built in 1928, some of the plumbing has been replaced with copper, but not all. The water pressure is fine. What's up?

Noise when water is running is caused by someing in the system that is free to move around as the water flows.
Often it is at one location and caused by the valve that that location where the washer is worn and or the screw loose. Or it can be caused by some thing that gets in the line. Which can be a part broken off from a faucett or excess solder that was used and built up inside the pipe.
The noise can vary from a machine gun sound to whistle.
When it is caused by flow from several different faucetts then it is some common part of the system.
Usually the main shutoff valve. But also possible a pressure regulator is you have one or a water softener.

Sometimes the pipes will rub against the studs and make noises as well. When the pipes expand and contract as you change the water temperature inside the pipes sometimes they will make a noise as they rub against the structure of the house. Usually this kind of noise will stop within a few minutes of the water running as the pipes adjust to their new length.
