CRW Shower Head Shut-Off Valve Solid Brass Shower Head Flow Control. I love this valve because it is not only small and inexpensive but it's easy to use. My wife wanted a valve that she could turn on and off her overhead shower and this is perfect. I put in a Tee at the shower pipe and plumbed in this valve before heading up to the ceiling to mount her square raindrop shower head she has always wanted. This valve allows her to adjust the flow easily and should last a long time being brass and chrome. It's perfect for what we needed.
