Why is barely any water coming out of faucet?

If your valves are open all the way and you’re still experiencing slow water flow, then the cause might be a clog. The first place to check is the aerator. The aerator is the cap on your faucet where the water comes out of. It has a screen and, over time, sediment gets caught in it, which impedes water flow.

Is there an aerator in the faucet outlet? If so, remove it, and try turning on again. These often get clogged from debris you shake lose in the lines during installation. Some faucets also require you to remove part of the valve after installation to flush the lines, then re-install.
