Freeze Protection and Water Damage Prevention
Freeze protection and water damage prevention comprise measures that stop water-carrying pipework and plant in a facility from freezing, thereby avoiding frost damage and consequential water losses.
Hazard picture
Freeze damage occurs when water in pipework, heating systems or sprinkler installations freezes, expands and ruptures the pipe; the actual property damage is usually caused by the water released once the ice thaws. Lightly used or unheated parts of a building, outdoor pipework and heating outages during winter power cuts are particularly exposed.
Protection measures
Maintaining minimum heating throughout all rooms, even during temporary vacancy, and fully draining unused outdoor pipework before the cold season substantially reduce the risk. Exposed pipes in unheated areas should be insulated or fitted with trace heating; dry pipe or antifreeze systems are used for freeze-exposed sprinkler sections. An emergency plan for heating failures complements the technical measures.
Insurance relevance
Freeze damage is one of the most common recurring causes of water damage in winter. Property insurers frequently make cover conditional on warranties requiring minimum heating or draining during shutdowns and periods of non-use; breaching these can lead to a reduction in indemnity.
