Arrived to customers house for a service call about a leaking kitchen faucet. Upon arrival I diagnosed the problems to be a bad cold side valve and bad faucet. Switched out service stop valve underneath first, then when the sink was still running with faucet off I changed out kitchen faucet.went over options with customer and Installed delta 2 handle sink with sprayer and added only 1 service valve. After hookup everything ran smooth with no leaks or drips. Customer was very happy with services provided today.
