No cold water after turning valve back on
We just installed a new kitchen sink and faucet. The water has been off for about 2 weeks while we worked on the floor and cabinets. Today we turned the water back on, and there is no water coming out of the cold line below the sink. The valve seems to be opening fine, and the second shut off valve in the basement if defintely working OK, as I can turn on the water for the fridge, which is after the sink line branches off. Is it possibly sediment built up in the line to keep any water from flowing, there isn't even a trickle coming out. Thanks Mary
