Arrived to the home, customer states no water pressure on the cold side of there existing faucet. I first determined if the aerator was clogged which it was not. I next looked under the kitchen sink and discovered that the plumbing in the home is very new, with all quarter turn valves under the kitchen sink. The cold valve was completely off resulting in not having any cold after coming from the faucet. I turned the valve on and everything is now back to normal. I checked for any leaks under the sink and there are no leaks at this time. *Customer will need a hard copy of the invoice mailed to their home.
