Does HDPE pipe withstand ice plugs?
Water with in the pipe may freeze solid without damaging the pipe. However, ice blockages must be thawed before pumping is resumed. Care should be taken to limit the additional tresses imposed on a ‘frozen’ PE pipe since the pipe wall may already be in a state of stress if the contents were unable to expand longitudinally during the freezing process. Seasonal freeze / thaw conditions have little effect on this flexible, elastic piping system.
