Single Handle Vessel Bathroom Faucet in Stainless

Thank you for your question, Richard! The threaded portion of the flange is 1 3/8" and the top surface diameter is 2 1/8". This assembly should work with a 1 1/2" diameter drain. Please note the depth of the hole must be 1 5/8" to 2 3/8". Best regards, Edward

Thank you for your question, Ylimor! This faucet does not include a drain assembly or lift rod. We recommend using a push pop-up drain assembly. Best regards, Jon

Hi, Gall! Thank you for your question. The height of the Delta 774-CZ-DST faucet is 12 11/16" (322mm). Here is a link to the technical specifications sheet for further measurements: https://media.deltafaucet.com/SpecSheet/DSP-L-774-DST_A.pdf Best Regards, Rosanna

Thank you for your question, Beian! A lift rod can not be installed on model 774-SS-DST, due to the fact there is no hole for a lift rod. The lift rod can be installed with model 574-SSMPU-DST, which is also in the Zura collection. Feel free to contact us directly, if you need further assistance. Best Regards, Benjamin

Hi John B, Thank you for your question about the Delta Faucet model 774-CS-DST. In our DST (diamond seal technology) faucets water does not contract with metal inside the faucet. Reverse osmosis takes so much out of water that it becomes aggressive to materials. Currently, our beverage faucet models are the only faucets designed to handle RO filtration systems. https://www.deltafaucet.com/kitchen/specialty-faucets/beverage Please reach out with any additional questions!

Hi Dpin, Thank you for contacting Delta Faucet Company! Please accept our sincere apology for the inconvenience you are experiencing. Here is what we can do to resolve your issue for you. Our Delta Faucet Zura® Single Handle Vessel Bathroom Faucet In Matte Black MODEL#: 774-BL-DST includes a stream straightener that can not be removed, if the flow is lower than normal we would recommend cleaning the flow restrictor. Please see the steps below to clean out the flow restrictor. Start by turning off both hot and cold, place the handle in the on position to drain out the residual water. Next, place a bowl or bucket in the cabinet directly below the waterline with the blue clip. Remove the blue clip by unsnapping it from the waterline, pull the lines apart, and you should see a small flow restrictor. The restrictor would need to be cleaned out and then reinstalled for full pressure. Please see the link below to the parts diagram showing where the flow restrictor is located. https://media.deltafaucet.com/PartsDiagram/DPD-L-574-MPU-DST%20Rev%20D.pdf Thank you for being a loyal Delta Faucet customer. We appreciate your business and look forward to continuing to serve you. Please contact us back with any further questions. Best Regards, Nicole
