Product review (5 stars): Do it yourself. It's easy.
Bought for my Whirlpool Duet washer.  This was amazingly easy to replace, using the video. You Tube.  I was surprised at the blockage on the screens of the old part.  We changed over our washing machine hoses at the same time.  Take it from a property adjuster, you want your hoses to be reinforced braided steel.
