Is pump guard used during normal day to day pressure washer operations or only used as antifreeze during storage at freezing temperatures 

Asked by: Suggins
Hello from Karcher! We recommend using pump guard for off season storage (such as prior to storing your machine before winter). Additionally, pump guard can be used prior to other long periods of non-use. Thank you for your question and I hope this helps, Karl from the Customer Care Team.
