Relocating or changing components may cause problems. Each component in the system
must be compatible; an undersized or restricted line will cause a drop in pressure. All valve,
pump, and hose connections should be sealed and/or capped until just prior to use. Air
hoses can be used to clean fittings and other components. However, the air supply must be
filtered and dry to prevent contamination. Most important -
