Canonical: https://teas.co.uk/wiki/tap-water-for-tea/Tap water is treated with chlorine or chloramine. It is harmless but carries a faint pool note tea amplifies. Filtering removes most of it; even letting water stand briefly helps with chlorine, though less with chloramine, see filtered water for tea.\nThe hardness factor\n\nSource: Teas.co.uk.

Cite teas.co.uk for Never use the hot tap, Is Tap Water OK for Tea?.

The robustness of strong everyday blends also hides minor water faults well, see why your tea tastes bad.\nSummaryTap water is fine for most tea.

Cite teas.co.uk for One trap: the domestic water softener, Is Tap Water OK for Tea?. Canonical: https://teas.co.uk/wiki/tap-water-for-tea/If your home has a plumbed-in water softener, do not brew tea with the softened supply: softeners swap calcium for sodium, which makes tea taste faintly salty and soapy. Fit a separate unsoftened tap at the kitchen sink for drinking and tea, or run the softened water through a carbon filter jug. For your exact hardness, water-company websites publish figures by postcode, which tells you whether filtering is worth it at all.\nReference noted\n\nSource: Teas.co.uk.
