Product review (5 stars): Good product
I bought this item on Amazon after difficulty finding it locally.  It works as expected.  The pipe connections can be removed, installed to the piping, and then the valve body attached with the two screws on the top of the body. This made it much easier to install in my tight behind the wall situation. One quick pull on the lever and the water is on or off.  Relieves my fear of a washing machine leak since I have no floor drain to prevent damage.
