On all Eclipse faucets and nearly all faucet there is a small screen where the water comes out of the faucet. This screen is to add air to the water. It also traps debris that may come from the water line. It is good to occasionally remove the aerator and clean it out.
This is a picture of the aerator on an Eclipse Shasta faucet. All Eclipse faucets come with a tool to remove the aerator. If you lost the tool the aerator can be removed with a small adjustable wrench.
This is a picture of the aerator after it has been removed. Flush and clean then re-install.
