Replace kitchen faucet and side sprayer with customer supplied faucet. Customers hot side shut off valve is not closing all the way. Customer had broken off the handle to their faucet and had bought a new faucet prior to arrival. Removed old faucet by cutting it off of the kitchen sink. Installed new one and tested and the the supply lines were not sealing on the new faucet. Replaced both of those and tested and everything is working as intended now
