Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. We recommend to tighten the set screws at the handles. If those are all the way tightened but the set screws aren't meeting the stems underneath, we recommend to unscrew the mounting hardware from underneath the sink and push up on the end valve so that the stem is higher so that the handle set screw can meet with the stem. If this doesn't fix the issue, 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 email@example.com.
