Filter housing was cracked & water was leaking all over the refrigerator

First I turned off the water supply to the frig and raised the bar in the ice make to stop the production of ice. I used the nut driver to remove 3 screws from the housing. I removed the connections from the two water lines & removed the broken housing. I attached the water lines to the new housing and then screwed it back into the refrigerator. I replaced the filter and screwed the filter cup into the housing. Turned on water & ice maker, then ran water thru the door dispenser to check to see if I had done it correctly. No leaks !!! Yeah....I was done !!!
