ROUTINE MAINTENANCE A well maintained pumping system will extend the life of the unit and will require fewer repairs. This means less down time which can be very critical when a constant delivery of water is required. A routine maintenance and inspection schedule should be set up on a weekly, quarterly, and annual basis with records kept of these a[...]
