Consumers and inspectors and other professionals advising their clients should note that these life expectancies have been determined through research and testing based on regular recommended maintenance and conditions of normal wear and tear, and not extreme weather (or other) conditions, neglect, over-use or abuse.  Therefore, they should be used as guidelines only, and not relied upon as guarantees or warranties.     

*********************************************************************** 

The quality of plumbing fixtures varies dramatically.  The mineral content of water can shorten the life expectancy of water heaters and clog showerheads.  Also, some finishes may require special maintenance with approved cleaning agents per the manufacturers in order to last their expected service lives.
