Hey there! Thank you for your interest in the Brizo 63075LF-GLLHP kitchen faucet. To install the faucet, first turn off water supplies and clear the sink area. Then, position the faucet with the base gasket in the sink’s mounting hole, next secure it with the mounting bracket and nut underneath, using a wrench. Connect the water lines, ensuring fittings are clean, and attach with the plastic sleeves, tightening snugly but not too much. Finally, turn on the water to check for leaks, adjust as needed, and ensure everything is secure. You can refer to its Installation Manual for more information. We hope this helps! Thank you for trusting PlumbersStock! Have a great day!
