Maintenance
Regular maintenance will ensure the longevity and optimal performance of your SIMPSON Monster Series pressure washer hose.
- Inspect Before Each Use: Check the entire length of the hose for any cuts, abrasions, bulges, or leaks. Also, inspect the quick connect fittings for damage or wear. Do not use a damaged hose.
- Proper Storage: After each use, ensure the hose is completely drained of water. Roll up the hose carefully to prevent kinks and store it in a cool, dry place away from direct sunlight and extreme temperatures.
- Clean Connections: Keep the quick connect fittings clean and free of debris to ensure a tight seal and prevent leaks.
- Avoid Sharp Objects: Do not drag the hose over sharp edges or abrasive surfaces that could damage the outer jacket.
- Bend Protectors: The integrated bend protectors are designed to extend the life of the hose at stress points. Ensure they are intact and functioning correctly.
Troubleshooting
If you encounter issues with your pressure washer hose, consider the following common problems and solutions.
- Hose Leaks:
- Check all quick connect fittings for secure attachment. Ensure the collar is fully engaged.
- Inspect O-rings within the quick connect fittings for wear or damage. Replace if necessary.
- Examine the hose for visible damage. If the hose itself is leaking, it must be replaced.
- Loss of Pressure:
- Ensure the hose is not kinked or obstructed, which can restrict water flow.
- Verify that the pressure washer pump is functioning correctly and receiving adequate water supply.
- Difficulty Connecting/Disconnecting:
- Ensure the quick connect fittings are clean. Dirt or debris can prevent proper engagement.
- Apply a small amount of silicone grease to the O-rings if connections are stiff.
