Třebomyslice is served by ČEVAK in the Plzeň Region, with a published value of 217.2 mg/L, very hard. The source date is 2025, so it may be older than the figures for most nearby places. The utility page does not give the water origin, so treat the geological reason as unconfirmed. Expect visible limescale on taps and in kettles.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
