Warning over water filters in icy weather

SHARE

Last year’s frigid winter has resulted in a Waitaki District Council review of how filters on water tanks are protected, after several hundred burst due to the cold.
More than 400 cases of burst filters on water tanks were reported to the council from around the Waitaki district in 2015, which kept council contractors and local plumbers busy.
Last winter was the worst in 10 years for burst pipes, plumbers told the Oamaru Mail. There were reports of pipes bursting in areas where they usually would not, such as properties on the coastline. While this winter is not expected to be as cold as last, council water services and waste manager Martin Pacey said staff had taken proactive steps to make sure if there was a particularly cold snap, it would not affect water users as much.
“Normally, we only get a handful of problems during winter,” he said.
“As a result of last year, we have reviewed and changed how we protect filters _ for example, using more protection or installing a box in the ground where practical.”The council also planned to trial “filter-free” restrictor installations to minimise freezing issues.
People are encouraged to check their filters are frost-protected with lagging and to make sure filters are kept as dry as possible.
They are advised to get in touch with the council if they have any issues.
