Product review (5 stars): A LG washing machine valve replacement that did the job.
Thanks to a YouTube video I quickly found out what was leaking in my LG washer. This set of inlet valves was the problem. I was a little put off that when I ordered it on Sunday afternoon with 1 day Prime delivery, it was scheduled, and arrived on, Wednesday.

The valve works as it should. Thanks to Amazon for having it and the YouTube poster for figuring it out for me!
