Hi KATHRYN,
Thank you for your review of the Peerless Faucet PRECEPT® Single Handle Kitchen Faucet with Spray Model: P199152LF. Please accept our sincere apology for the leak you are experiencing. We would be more than happy to assist you. Quality is very important to us and our products undergo rigorous testing to ensure high-quality performance.
It is possible that a flush could resolve this issue. To flush the supply line, first shut off the hot and cold-water supply. Remove the hot supply line from the shut-off valve and place the line into a bucket. Open the handle to the fully open middle position, and then turn the cold supply back on for one minute. The cold water should flow through the faucet and out the hot supply tube. Reconnect the supply line and repeat with the second line.
We appreciate your business and look forward to continuing to serve you. Please contact us directly if you have any further questions.
Best Regards,
Kelley
