Single Handle Pull-Down Kitchen Limited Swivel in Black Stainless

Hi, Skip52! Thank you for your question. The handle assembly for the Delta 9159-KSLS-DST Faucet has a small button that hides a set screw. Remove the small button by popping the button out with something flat like a flat head screwdriver. The set screw can be unscrewed from the handle with a 1/8" Allen wrench. Best Regards, Rosanna

Thank you for your inquiry, David! The sprayer/wand assembly of the Delta Trinsic Pull-Down Kitchen 9159-DST faucet is non metallic and it operates in an aerated or spray mode via ergonomic buttons. Best regards, Tanya

Hi, Aaron! Thank you for your question. We do not have Delta Trinsic faucet that does not have pull down sprayer assembly. We also do not have sprayer assemblies that have just the stream mode option. Best Regards, Rosanna

Hi, Akko! Thank you for your question. We do not recommend to install a water filter to the Delta 9159-AR-DST Faucet sprayer assembly, as potential pressure fluctuations during water filter operation may result in the hose rupturing. Best Regards, Rosanna

Hi, wbcIII! Thank you for your question. The Delta 9159-BL-DST faucet may not be shipped to Brooklyn, NY 11237 as it has a flow rate of 1.80 GPM @ 60 PSI. The maximum flow rate to be within the NYC Green Code is 1.5 GPM @ 60PSI. Best Regards, Rosanna

Hi there Becca, Thank you for your inquiry! A comprehensive list of cleaners is impossible to recommend because of the variety of materials that are a part of our many models of faucets. What may be fine for a spout may damage a handle. To clean, simply wipe gently with a damp cloth and blot dry with a soft towel. Stubborn hard water spots are best avoided by this daily regime. If extra measure is needed, a solution of 50% white vinegar (never Apple vinegar) could be used by wiping, spraying or soaking. Caution: Vinegar can permanently damage porous rock surfaces such as granite or limestone countertops. Use extreme care if such a surface is in the vicinity. To soak a faucet or part still on a faucet: 1. Mix white vinegar and tap water to a half and half proportion. 2. Put a rag or towel in the solution to soak it up. 3. Wrap the rag or towel around the part. 4. Let sit for up to an hour or so. 5. Use the rag or a clean, soft toothbrush to scrub the remaining hard water buildup. o Avoid harsh abrasives or polish o Avoid bleach-based cleaners o Avoid industrial cleaners and abrasive cleaners, such as those used for toilet bowls, green Scotch-Brite heavy duty scrub sponges, Scrubbing Bubbles Bathroom Cleaner and Lysol Basin Tub, Soft Scrub, and Tile Cleaner. o Avoid products that state on the label that they remove tarnish and rust, and those containing hydrofluoric, hydrochloric and/or phosphoric acids and caustic agents. o Because cleaning formulas can change without notice, Delta Faucet Company does not endorse any specific cleaner. Best regards, Tanya

Hi Gary, Thank you for your question. The model 9159-AR-DST does have an aerator that is part of the wand assembly that controls the flow of water when the faucet is in stream mode. Thanks, Dave

Hi, Thank you for contacting us. We apologize for any inconvenience. We are more than happy to help you. Reduced flow or no flow is typically caused by debris. If only one side is affected, there is debris in the supply line. To flush the supply line, first shut off the hot and cold water supply. Remove the hot supply line from the shut off valve and place the line into a bucket. Open the handle to the middle position, then fully open, then turn the cold supply back on for one minute. The cold water should flow through the faucet and out the hot supply tube. Reconnect the supply line and turn on both supplies. Check flow from the faucet. If this does not help, please let us know. Please contact us at 1-800-345-3358 if you have any further concerns. We are open Monday through Friday 7:00 AM to 7:00 PM central time, and 8:00 AM to 5:00 PM on Saturday. Best Regards, Bethany
