Next open the faucet in the galley sink to relive any pressure in the line. Return to the engine room and using
your hands grasp the housing at the top and gently turn the filter housing counter clockwise to remove it.
Water will escape and drain down through the bilge. Replace the filter with the new one and reattach the
filter housing securely to prevent any leaks.
Close the faucet in the galley and turn the ball valve in line with the supply line as shown in the picture
below. Have someone turn the faucet on while you check to make sure the filter housing is not leaking.
