Frequently Asked Questions

Sprayer Hose

My hose doesn't extend as far as it used to. What could be wrong?

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

My kitchen spray attachment is not working. What can I do?

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.

My vegetable spray hose is leaking, why?

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.

Sometimes I have a mixed spray and stream pattern coming from my pull-out. What could cause this?

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.

The spray does not come out of my pull-out wand as strong as it used to. What can I do to fix this?

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.

What do I do if my pull-out kitchen spray assembly is cracked?

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.

Why does my faucet jump when I use the sprayer?

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.

If problem persists, we recommend replacing your aerator (Delta® Genuine Part RP18508).

Answer: 
Hi Tomy, Thank you for your question. What you describe is normally the remaining water in the high arc spout running out of the faucet. Unlike a traditional spout that is tilted backwards the high arc spout allows the water remaining in the spout to drain out after the faucet is turned off.
Thanks,
Dave

Hi Blaze, Thank you for you question. The RP37033 spout hose and RP39345 hose and spray assembly are complete assemblies. The hoses come with the round quick connects already attached. The replacement parts do not come with the RP13938 o-rings that are located on the studs coming down from the faucet where the hoses connect.

Hi Diane, Thank you for your question. You will want to change out the seats and springs on the diverter valve to stop the leak. The part number will be either RP4993 or RP28603 depending on which generation of the 1800 faucet that you have. I have attached the manual below to help identify your faucet and the needed part.

PALO ability to sustain sprayer with low pressure flow

Looking at the PALO 467-SS-DST.
If I turn the water flow down to very light while the faucet head is in spray mode, will the head stay in spray mode or jump itself into non-spray mode?

Answers

Answer: 
Hi Adda, Thank you for your question. To disconnect the RP50782RB sprayer from the faucet you will need to pinch open the bottom of the gray fitting on the hose assembly that is attached to the faucet under the sink. Once the fitting is open, push up slightly and then pull down to remove the hose assembly. You will be able to remove the entire assembly out of the hose support on top of the sink. Thread the new spray hose assembly back down through the hose guide and simply push the new quick connect fittting onto the faucet.

Dave

I have a model 21925-SS faucet set I need to reconnect the sprayer

We had new counter tops put in am reinstalling the model 21925-SS faucet set. I installed this set in 2010 it has performed outstandingly. The installers disconnected the sink and faucets. I have hooked it all up except for the sprayer hose. I finally deduced how the quick disconnect fits on the sprayer hose. Dry testing it on the faucet set it seems loose. Due to the extremely tight space I want to make sure that this is ok before I reinstall it and turn on the water. I do not want to have water all over the inside of the sink cabinet. The quick disconnect consists of 2 gray pieces of plastic and 1 oval shaped spring. I figured out that the oval spring fits diagonally across the 2 plastic pieces. The small rectangular tabs apparently fit into the slots in the sprayer hose fitting that slips onto the faucet center position fitting. Thank you for your assistance.

Respectfully,

Answer: 
Hi Carl, Thank you for your question. We do not recommend that the quick connect fitting on the veggie spray hose be taken apart. The connection can be removed by simply squeezing the fitting open. If you feel that the connection is not tight enough, you may want to replace the RP37034BL (black) or RP37034GR (gray) quick connect veggie hose.

Dave

Delta Sprayer Quick Connect Piece came undone

While using the sprayer my wife heard a quick pop, followed by spraying under the sink. After looking under the sink we noticed the hose came apart from the junction as shown in the linked video. It appears that the quick connector piece maybe broke in half?

Where is my diverter valve located.

Hi, I have a high arc kitchen faucet with soap dispenser and sink sprayer (so valve handle is NOT contiguous with faucet). Sprayer no longer shuts off faucet and takes 100% of flow. Rather, takes about 50% of flow. Understand need to clean diverter, but is it with the faucet? Or is it with the valve?

Answer: 
Hi Andy, Thank you for your question. In most cases the diverter should be part of the valve assembly. If you have one of our newer DST models the diverter is underneath the counter where the sprayer attaches to the faucet. I have attached a link to the manuals for these 2 styles below. The parts breakdowns should help you with your repair.
Thanks,
Dave

Answers

Answer: 
Hi Saints, Thank you for your question. To remove the RP50390 hose assembly first remove the clip attaching the hose to the faucet underneath the sink and then pull the hose off of the supply tube. You should be able to pull the hose up through the faucet hub. Sometimes it is easier to pull the hose up with the spout facing all the way to the left or right. You can also twist the hose while pulling to assist with removal.
Thanks,
Dave
