Thank you for your question, and I am sorry to hear that you are experiencing a leak from your Delta faucet. We do recommend to flush the valve to make sure no debris is stuck that is causing the leak. To flush, first turn off the water supply to the faucet. Remove the handle assembly, unscrew the bonnet ring and remove the cartridge assembly and all seals. Rinse and clean the cartridge out thoroughly. Turn both the hot and cold water back on for 10 to 15 seconds to flush out the valve body. After the allotted time, turn the water off and reinstall all of the components. Make sure that there is no debris on the cartridge assembly and seals.
If this does not resolve your issue, then the adapter assembly, RP46073, may need to be replaced.
