The white crystals in your plumbing water lines are most likely calcium showing that you need to have your water checked to see if it is hard or soft. One way to know is if your soap gets really foamy or not. If it lathers then it is some other problem.

It may be calcium, fluoride or similar deposits from years of water flow. Water contains small amounts of minerals/metals and these build up over time.


Answer by  kipcat (1964)

You likely live in a water district that treats it's water with calcium and fluoride. This causes a build up on the appliances when water evaporates and leaves behind the minerals. These deposits are a nuisance but harmless. Get some CLR and clean it off.
