Hi Claude, Thank you for your question about the Delta Faucet model 400-DST. Unfortunately, the spout is not designed to be removable. I recommend soaking the area with 50/50 white vinegar and water to help remove mineral deposits that may be causing the issue. Please reach out with any additional questions!

Hi JoJo, Thank you for your question about the Delta Faucet model 400-DST. Some models of sink have a recessed area for installing a faucet that has drill points for an 8" installation that this faucet uses. But there does not appear to be a drill point for the sprayer on the sink ledge. I recommend confirming with the sink manufacturer if the sink accommodates a 4-hole 8" installation. Please contact us directly if you have any additional questions! Best Regards, Bryan Digital Communications Specialist

Hello Butch, Thank you for your question! I am sorry that the information you are inquiring about the Delta Faucet Single Handle Kitchen Faucet With Spray, model 400-DST, is not readily available; however, I am happy to help you. The correct part number for the Sprayer and Hose Assembly for model 400-DST is RP60097. RP60097: https://www.deltafaucet.com/parts/product/RP60097.html We recommend flushing your unit. Parts Diagram: 400-DST https://media.deltafaucet.com/PartsDiagram/DPD-K-100-DST_A.pdf Flushing your Single Handle DST Kitchen Faucet What you need before you begin: 1/8”-Allen wrench Bucket Strap wrench Second pair of hands Towel Before beginning, please turn off the faucet at the shut-off valve, and cover the drain for your sink. To begin, you will need to remove the set screw on the handle with the Allen wrench. When the set screw is removed, you can remove the handle, sleeve assembly, bonnet, and valve assembly. Please note that some people may need to use a strap wrench to loosen and or remove the bonnet; that is okay. With the valve of the faucet empty, go ahead and place the towel behind the back of the faucet; then put the bucket over the top of the towel, allowing the bucket to sit over the faucet; where the handle would be. Turn the cold-water valve on, allowing the water to run up in the bucket and down into the sink. Allow the water to run for at least 60 seconds for the best results. Once the time is up, go ahead and turn the cold-water valve off. Turn on the hot water valve and do the process once more. Please wipe off the puck (which is where the valve assembly sits inside of the faucet) with a soft cloth before putting it in your valve assembly. Flushing the supply lines at the shut-off valves What you need before you begin: Bucket Towel Please shut off the valve for the cold-water line. Next, disconnect the cold-water line from the shut-off valve and place it into the bucket. Place the handle in the on-position and at what would be considered lukewarm temperature. Next, turn on the cold-water valve and allow the supply line to bleed for at least 60 seconds. When the time is up, turn the valve back off and attach the supply line back like it was before. Now you can move onto the hot water line. Go ahead and shut off the valve. Remove the hot water supply line from the valve and place it into the bucket. The handle to the faucet should still be in the lukewarm, on-position as before. Next, turn on the hot water valve and allow the supply line to bleed for at least 60 seconds. When the time is up, turn the valve back off and attach the supply line back as it was before. Thank you for being a loyal Delta Faucet customer. Best Regards, Emma
