This product exactly matches my current Reidell valve which had broken, making it impossible to completely turn off the valve. The old volume control/shutoff could not be repaired as the Reidell company is no longer in business. Fortunately, this new Lawn Genie brand exactly matches the old valve. All I needed to do was unscrew the old valve's volume control/shutoff component (see photo below) and screw in the new matching component, as the threads matched exactly. Now, no more problem. If anyone has a similar problem or questions, I'd be happy to respond by email.
