Tech removed old Delta faucet, however upon removal of old faucet old shut off valves were leaking, tech cut out hot water side and replaced with a ball valve. However cold water side had two valves so tech cut out old gate valve and due to interference with new faucet hose line, a ball valve was not installed. New delta warranty supplied faucet from customer was installed, no leaks or malfunctions are present at this time. **** Mail copy of invoice to customer
