Genuine OEM Whirlpool Refrigerator Water Filter Housing. Housing has two Quick Connect Style Fittings for the water lines. Many customers make the mistake of using a screwdriver to pry the water line out, damaging the housing. You simply need to depress the tab surrounding the water line. At the same time, while holding down the tab, gently pull the water line out. When installing a water line, use gentle pressure to insert water line. Do not force it. Once it is in place, you can gently pull on it, but it should be locked in and should not pull out.
