How do tap water pipes stay clean for years

716 views

I’ve been drinking tap water all my life and I have to wonder: Tap water pipes have a lifespan of 50 years, without any regular cleaning and maintenance. I have to clean my aquarium every week and even after cleaning it I wouldn’t drink from it. I know light and air play it’s role, but still, 50 years? Is the inside of the pipes really staying that clean or is it that the dirt in there doesn’t really bother us?

Think about how clean your aquarium would be if you cleaned it out several times a day. Every time you wash your hands in a sink, wash dishes, flush the toilet, take a shower you are changing out the old water with new water.
