For this job we install a new seal for the customer supplied faucet. In order for us to replace the old seal, we needed to uninstall the faucet amd reinstall the faucet to install the new seal that the customer provided us to install. After the install, we soaked the granite to see if it would leak down, no leaks customer is all set. New seal had the perfect fit, the previous seal looked like it was cut the installed after the faucet was installed. No issues at this time
