I have this problem with two sinks. One is a single handle fixture, the other two handled. On both, I have very low pressure when I turn on the cold water. The hot water pressure on both fixtures is fine. I'm guessing there's sediment in the line somewhere? Do I just start at the water cut off cleaning everything as I go and blowing the everything out? Thanks!

Hi JP

Star by making sure the cold water shut off valves are wide open. If that fails to resolve the issue, you could shut the cold water off to the faucets and test the flow from the supply tubes to the faucets (direct tubes to bucket and turn water supply on). If flow is strong and faucets are still weak after reconnecting the supply tube then the issue is up inside the faucet. If the flow is restricted when testing the tubes, I would disassemble the shut off valves and see if the washers have come loose and are blocking flow (use flashlight to inspect interior of shut off valves).

Start there... post back.

Thank you Mark, I will check that this week and report back.
