Check Your Water Hardness by Eircode

Free · Takes 10 seconds

What's your water actually doing to your house?

Enter your eircode and we'll show you the official hardness reading for your supply zone — and what that level of limescale costs an Irish home every year.

Just the first 3 characters will do (e.g. R32). We don't store your eircode.

That doesn't look like an eircode — try the format R32 XXXX.
