Function of the Water Supply Tube Assembly
The N018155 Water Supply Tube Assembly is designed to:
- Deliver water to the saw blade during cutting
- Cool the blade to reduce heat buildup
- Minimize airborne dust during wet cutting
- Improve cutting efficiency and blade life
- Help produce cleaner, smoother cuts
- Restore the factory water delivery system
Using a genuine OEM replacement tube assembly helps ensure proper water flow for safe and efficient wet tile cutting.
Common Signs Replacement Is Needed
Replace the water supply tube assembly if you notice:
- Cracked or split tubing
- Reduced or uneven water flow
- Water leaking from the tube
- Clogged or restricted water passage
- Blade overheating during wet cutting
- Tube damaged from normal wear or impact
A damaged or clogged water supply tube can reduce blade cooling, increase dust, and shorten blade life.
Installation & Service Notes
Disconnect the tile saw from the power source before performing any maintenance.
Turn off the water supply and remove the existing N018155 Water Supply Tube Assembly from the water delivery system according to the manufacturer's service instructions. Inspect the fittings, nozzles, and related water system components for debris or damage before installing the replacement tube. Route the new tube in the same manner as the original, ensuring it is fully seated and free from kinks or sharp bends. After reassembly, restore the water supply and verify steady water flow to the blade before operating the saw.
Important: Always verify your tile saw model and original part number before ordering. Inspect the water nozzles, fittings, and hoses during replacement and clean or replace any components that restrict water flow.
Maintenance Recommendations
- Flush the water system after each use to remove sediment.
- Inspect the tube regularly for cracks, wear, or blockages.
- Use clean water to help prevent mineral buildup.
- Avoid sharply bending or pinching the tubing during storage.
- Clean the water nozzles periodically to maintain proper spray coverage.
- Use genuine OEM replacement parts to maintain factory fit, reliable water delivery, and long-term wet tile saw performance.
