What causes slow water flow after cold water hook up
hooked up new faucet. cold water is hardly flowing
Disconnect the fittings. Then when they are disconnected, open them up to flush out any crud in the lines. (point them into a bucket, or plastic bag (with no holes in it)It won't take much, (maybe a half gallon or so) to flush out any crud from the valve and line.You You may have to dissasemble the faucet to clean out any crud that has clogged up the faucet too.Curious. Did you replace the original because of 'low flow'? It may not be the faucet, but the actual water line that it clogged.
Did you turn the shutoff valve all the way on?
Maybe because it freeze last night
is the screen possible now clogged on the end of the spiggot?
Try switching the cold/hot hoses and see if you get low hot water pressure.
