Water safety

Why does my 20L jar water taste or smell different? 6 common causes

By the Refillr team, KottayamUpdated 4 min read
Short answer

A change in taste usually comes from heat or sunlight on the jar (plastic taste), an unclean dispenser (musty or stale taste), a different mineral level (flat or salty taste), or a new dispenser or cup. Stop drinking water that smells musty, chemical or rotten, or looks cloudy or green, and ask for a replacement.

When to stop drinking it

  • The water is cloudy, has floating particles or a green tinge.
  • It smells of fuel, chemicals, sewage or rot.
  • The seal was broken when it arrived.

In any of these cases, do not drink the water. Take a photo of the jar and label and ask for a replacement.

Frequently asked questions

Why does my can water taste like plastic?

Most often the jar was stored or carried in the sun or heat. Ask for a replacement and keep jars indoors in the shade.

Why does water from my dispenser taste stale?

Usually the dispenser reservoir or taps need cleaning. Clean it every 3–4 weeks, and more often in the monsoon.

Is it safe to drink water that smells strange?

No. If water smells of chemicals, fuel or rot, or looks cloudy or green, do not drink it and ask for a replacement.
