Function of the Water Supply Hose

The Centurion 7485 provides a dependable water supply between the water source and pressure washer, helping to:

• Deliver consistent water flow
• Maintain proper inlet water volume
• Support efficient pressure washer performance
• Reduce hose twisting with the swivel fitting
• Withstand daily commercial use

Its 3/4-inch diameter allows greater water flow than standard garden hoses, making it ideal for pressure washers requiring higher inlet volume.

Common Signs Replacement Is Needed

Replace the hose if you notice:

• Cracks or splits in the outer cover
• Bulging or soft spots
• Leaking fittings
• Kinks restricting water flow
• Excessive abrasion or wear
• Damaged swivel fitting
• Reduced water delivery

Replacing a damaged water supply hose helps maintain proper water flow and protects pressure washer pumps from inlet starvation.

Installation & Service Notes

Before installation, inspect the hose and fittings for damage.

Connect the MGH end to the water source and the FGH swivel end to the pressure washer inlet. Tighten connections securely without overtightening, then slowly pressurize the system and inspect for leaks before operation.

Important: This hose is designed as a water supply hose and is not intended for use as a high-pressure discharge hose between the pressure washer pump and spray gun. Always verify compatibility with your equipment's inlet flow and pressure requirements.

Maintenance Recommendations

• Drain the hose after each use.
• Avoid sharp bends or kinks during operation.
• Store loosely coiled in a clean, dry location.
• Protect the hose from prolonged UV exposure when not in use.
• Inspect fittings and the swivel connection regularly for wear or leaks.
• Replace the hose if signs of deterioration or leakage are observed.
• Use only clean water to help maximize hose and pressure washer performance.
