Vástago y válvula

Thank you for your question, Gene! There is no specific tool provided or recommended to remove this bonnet nut, however a pair of adjustable pliers and a strap wrench should make removal easier. If there is significant mineral buildup, a 50/50 solution of white vinegar and water can be applied to help break up any deposits inside the bonnet nut. If you need further assistance, please contact us at 1-800-345-3358 or email us at customerservice@deltafaucet.com. Best regards, Edward

Hello Valued Customer, Thanks so much for contacting Delta Faucet Company! The ARA® Stem & Valve MODEL#: RP90056 can be replaced by removing the button and set screw from the handle. Then, pulling the handle, cap, and bonnet nut off. The old stem can then be pulled out of the valve and changed. Please reach out with further questions!

Hi Steve, Please accept our sincere apology for the inconvenience you are experiencing. We are happy to help! Most 568LF faucets have a 3/32" hex or Allen set screw under the cover button on the back of the handle. If there is difficulty loosening the set screw or removing the handle, we recommend soaking the area with 50/50 white vinegar and water. This can help remove mineral or water deposits. For models produced after 08/21/2022, the handle is removed without tools by pulling straight up and off. Please reach out with any additional questions! Best Regards, Bryan Digital Communications Specialist
