Why aren’t taps and pipes filthy on the inside?

1.54K views

So kitchens and bathrooms need cleaned regularly. The moisture and food in these rooms specifically make it easy for pathogens to grow. Plenty of people get mould problems in their homes. Kitchens need cleaned with disinfectant sprays to make them safe to produce food in.

What about the inside of taps though? Depending on the age of your house, the pipes and taps could be decades old, and will have never been cleaned on the inside, yet we don’t think twice about pouring a glass of water. Why is this? How are the insides not full of rust, grime and bacteria?

Back when I was in high school, we’d come back from summer vacation and the fountain water would run a reddish-brown, presumably from rust in the pipes. But after running it for a minute or less, the water ran clear and would stay that way the rest of the year with normal use. So, I’m thinking not only the chlorinated water helps, but the regular movement of water through the pipes helps to clear any debris that might otherwise have gathered.
