Many water sources used for public water supplies in New Zealand are plumbosolvent. This means that the water is slightly acidic and can dissolve metals such as lead and copper out of brass fittings, if the tap has not been used for a period of time.

Council’s water supplies for Blenheim, Picton, Renwick and Havelock are plumbosolvent.

The Ministry of Health requires the following notice to be printed six monthly to advise consumers of this:

Ministry of Health – Public Notice

Some plumbing fittings have the potential to allow minute traces of metals to accumulate in water standing in the fittings for several hours.

Although the health risk is small, the Ministry of Health recommends that you flush a mug full of water from your drinking-water tap each morning before use to remove any metals that may have dissolved from the plumbing fittings.

We are recommending this simple precaution for all households, including those on public and private water supplies.
