Thank you for your question. I am sorry to hear that you are experiencing an issue with your faucet. If the hub assembly for the faucet does not swivel, we recommend to replace the hub assembly, RP51489, and o-ring, RP44648. Here are links to these parts:
If these parts do not fix the issue, we recommend to replace the faucet altogether. For more assistance with this, please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST. You may also email at firstname.lastname@example.org.
