Your washer has always worked well in fact, it still does, but the cycle time seems to drag on longer and longer. Hard to tell what's wrong, but you notice the water doesn't seem to spray into the laundry tub like it used to, and it seems to take longer to fill the tub. Why?

Well, you've figured out the problem — low water flow to the washing machine. Low flow means it takes longer for the tub to fill, and cycle times are stretched out.
