Hi, doug m!
Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. We do recommend to flush the valve body to make sure no debris is stuck inside causing the temperature change. If this does not 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 firstname.lastname@example.org.
