I am trying to replace my water filter housing. How do I remove the two water lines going into the housing (Part #2199840)? Do I have to pull the frig (it is built in) away from the wall or can I pull the lines out from the front of the frig. I tried pulling on the water lines but they are in there with some kind of washer. It is very tight quarters trying to access the housing. I was able to remove the drip pan which gave me a little bit of room but I can figure out how to safely remove the lines without destroying the washers.
