Hi, Sue!
Thank you for your question, and I am sorry to hear that you are experiencing a leak at your faucet. We do recommend to flush the lines for any debris that might be effecting the internal parts. Also, we do recommend to replace the seats and springs and stem unit assemblies for your drip. The seats and springs is RP4993. The stem unit assembly is RP24096. You can also use RP25513.
Best Regards,
Rosanna
