Delta Model 470: Signature Kitchen Pull-Down/Out Faucet - White - Answered Questions & Fixed issues
My Delta kitchen faucet is putting out small black particles with the hot water. What can I do to stop it?
Is the kitchen faucet the only problem? If not, then the water heater or other problem may exist in the water system.When you run the hot water, are the particles always coming out or do they go away after while?Black particles can be caused by carbon water filters. Do you have a filter? Those particles stop over time. Washers and "O" rings that are wearing out can cause black particles. I would check under the sink to see if you have any slow drips. You may see white, green or black colors along the fittings.I've also seen black particles from algae in the line. Maybe there's a leak somewhere in the system that dripping and cause the algae to form? Inspect your water lines and checking for leaks anywhere in the system may help. If you turn off all your faucets, washer, hose bibs and check the water meter, is it still moving? I'd check it every 15 minutes for an hour to see if there is a slow leak.Here's a diagram that shows all the parts:

Hose assembly
Shut off main water to home. Then check if a clip is guarding the nut to nut threaded connection the use 2 wrenches to un screw.Cover tools "teeth" with tape or thin rubber to prevent marking on chrome/etc finishes.

Faucet does not completely shut off when properly
This problem exists when the seats get wore a and there is no resistance to shut water off. Replace the seats and springs to correct this problem. Shut water off and remove handle with a allen wrench and retaining collar to expose the valve body to gain access. Once apart remove seats and springs and reassemble and problem should go away.
How can I remove wand
Go ahead and buy the new hose ant it will come with installation instructions and you will see how it comes apart at that joint.
