strong hot water, but a trickle on the cold

[Son of a Sailor]

Hey everyone,
before i tear into this faucet (because its a tight fit behind the sink) in one of my heads, i want to ask if anyone may have an idea as to why i would be getting strong pressure and flow through all faucets and in the galley and heads but one. this faucet gets good hot water, but just a trickle through the cold water side. is it clogged somewhere? and how/where would i turn the water supply off inorder to dismantle the faucets? thanks guys

Have you checked that the supply pipe to the tap isn't kinked or crushed? It's usually 9/16" flexible PVC water hose - easy to crush or even just to get kinked if it's turning a corner too tightly.

I turn off my fresh water pump.

Yes, simply turning off the pump should be all you need to do. A simple test will tell whether you're dealing with a clog or some other problem. Disconnect the cold water line from the faucet, stick that hose into a bucket, and turn the pump back on. If you don't get flow, the problem is in the plumbing between the pump and the faucet. If you do get flow, the problem is probably in the faucet.
