The hose for the pull-out faucet is flexible. Make sure it isn't caught on something underneath the sink.

The most common cause is mineral deposits in the sprayer. Remove and soak it in a 50/50 vinegar and water solution for several hours. The second most common cause is a kinked hose under the sink. Check to be sure the hose doesn't kink when the sprayer is pulled out to be used. Third, the problem may be a blocked or damaged diverter assembly. Follow these steps to solve:

To access the diverter -- Single-handle faucet:

1. Shut off water supply under the sink.

2. Cover drain opening so parts won’t fall into it.

3. Remove the handle, cap, cam, packing and ball assembly.

4. Gently rotate and lift off the spout.

   
   
   

    

5. Remove the diverter assembly. Be sure to remove the entire diverter.

   
   
   

    

6. Insert a flat head screwdriver or an Allen wrench into the body cavity to pop out the diverter. Check for debris on the diverter, as well as in the diverter cavity in the faucet body.

7. Clean the diverter thoroughly by soaking in a 50/50 vinegar and water solution for two hours; reinstall. If diverter appears damaged, replace it with Delta® diverter RP320.

To access the diverter -- Two-handle faucet:

1. Shut off water supply under the sink.

2. Cover drain opening so parts won't fall into it.

3. Unscrew and remove the spout nut. Use a crescent wrench to loosen if necessary.

   
   
   

    

4. Unscrew the diverter from the top of the body using a coin

   
   
   

   
   (if the diverter is plastic) or a screwdriver (if the diverter is metal). Be sure to remove the entire diverter.

5. Clean the diverter by soaking in a 50/50 vinegar and water solution for 2 hours. Flush any debris from the opening.

6. Replace the diverter and spout nut.

   
   
   

   
   Check to see if the diverter functions properly. If not, replace it with Delta diverter RP6073. Be sure that the old diverter gasket is removed from the diverter cavity. The new diverter may not operate correctly if the old gasket is not removed.

Be careful not to over tighten the diverter.

NOTE: Old style metal and current-style plastic diverters are interchangeable.

The white retainer and o-ring were most likely displaced through installation and removal of the quick connect hose connections.  We suggest that you replace the vegetable sprayer hose.  The exact repair part will depend on the model and age of your faucet.  Please call 800-345-3358 for assistance in determining the correct replacement for your model.

The pull-out uses a side-to-side diverter to change spray patterns. Make sure the diverter is pushed all the way to one side or the other to avoid a mixed spray/stream pattern.

There may be debris caught between the wand and the hose. To check for debris:

1. Shut off water supply under the sink.

    

2. Unscrew the wand from the hose.

   
   
   

    

3. Tap the screen in the wand to remove debris.

   
   Note: Do not disassemble the wand.

    

4. Screw the wand back on the hose.

    

Also, the face of the pull-out wand incorporates Touch-Clean® nozzles. To ensure proper spraying, wipe the face of the wand to loosen and break away residue and mineral deposits from the nozzles.

It will need to be replaced. To determine the part number for your faucet model, contact your Delta plumber or showroom, call 1-800-345-DELTA (3358) or e-mail us.

This could happen if there is debris in the faucet or water supply lines, or the diverter assembly could be malfunctioning.

1. Turn off the water supplies.

2. Disassemble and remove all internal faucet components.

3. Place and hold an upside-down bucket over the faucet to deflect water into the sink.

4. Carefully turn water supply on and let run one minute.

5. Turn water supply off.

6. Reassemble the faucet.

7. Turn water supply on.
