Thank you for your question and I am sorry to hear that you are experiencing low flow from your Delta faucet. We recommend to flush the lines and clean the debris screen at your solenoid assembly under the sink. To flush the lines, make sure your handle is in the 'off' position. Disconnect the top hose from your solenoid assembly and point it into a bucket. Turn on the water from your handle and let the water flow through the open hose into the bucket. Does it have adequate flow? Since the hose is disconnected, this is a good time to take the debris screen out of the solenoid. The debris screen is located in the opening of the solenoid where the hose was connected into. Take a pair of needle nose pliers and pull the small debris screen out. Clean the debris screen by rinsing it in running water at another faucet in your home since your kitchen faucet will be disconnected. Install it back into the solenoid and connect everything back up. Turn the handle in the off position. Disconnect the hose from the bottom of the solenoid. Point the whole solenoid into the bucket. Turn the handle in the 'on' position. Flush the solenoid through.
If this does not fix the flow 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 firstname.lastname@example.org.
