Protecting your water system in a cold snap
Farmers have been advised to assess their water system to see if they are vulnerable to a serious cold snap, according to Teagasc’s Farm Management Specialist Tom Ryan.
With regards to water troughs in fields, especially concrete troughs, Ryan advises farmers to make an effort to empty them and leave them empty if they are not in use.
If a farmer is worried about the water supply being disrupted by freezing temperatures, a tap can be fitted to help prevent the water freezing, Ryan said.
“Farmers could fit a tap at the end of the pipe serving the shed. During a cold snap this could be used strategically by opening the tap slightly to help prevent the water freezing,” he said.
