The water heater in my home is about 5 yrs old. It has started clicking constantly in the last day. Seems to be functioning fine, but has a loud, steady clicking. As best I can tell, its coming from somewhere near the top. When the water is shut off, it stops. In reading this group, it sounds like I may have a valve problem? It does sound like a small metal ball bouncing around inside the CPVC pipe. Can anyone help?
thanks!! Randy
