This not Diane, this is her husband Jeff.  This part was not purchased but I am attempting to lead a revolt against Whirlpool.  I purchased a reverse osmosis system and no longer need a filter.  I need the filter bypass plug that costs less than $5.  Whirlpool discontinued that part so that i have to continue to purchase filters annually at approximately $50 each.  This is a marketing plan to take advantage of all of us.  Stop buying Whirlpool.  If this is how they treat their customers, they don't deserve to have any.
