How this site works
Every page cites its lifespan figures, replacement costs, and adjustment factors to a real source — manufacturer documentation, trade associations, or widely-cited cost guides. Each page also includes a rule-of-thumb "estimated remaining lifespan" tool based on your item's age and, where a sourced adjustment exists, real-world factors like water hardness.
