I bought this as an exact replacement for one I bought at Home Depot 2 years ago. They don't sell it any more, so I bought it here. The old one had started to leak, and now doesn't work at all. I'm kind of locked in to using the same size valve, because it minimizes the job of replacing it. It's not like changing a light bulb, after all. After some research, I have found out that some items purchased at the "Depot" are not as high quality as the "same" item bought elsewhere. I've had much better luck buying through Amazon. I just hope this one lasts longer.
