Some plumbing fittings potentially allow minute traces of metals to accumulate in water left in the fittings for several hours.
Although the health risk is small, the Ministry of Health recommends you run your tap for a few seconds each morning, or after a long absence from your property, before drinking or washing dishes.
This is to remove any metals that may have dissolved from the plumbing fittings.
For the purpose of water conservation, it is suggested you use this water for watering plants.
This simple precaution is recommended for all households in New Zealand, including those on public and private water supplies in the Christchurch and Banks Peninsula area.
