Page 55 VT551 - Maintenance Water Pump Repair Water pumps by their very nature are subject to erosion and wear from the process of pumping water. The life of the pump will depend on the quality of the water being used. The more particles that are in suspension in the water the sooner the seals and valves in the pump will wear and require replacing and are therefore considered as consumable items.
