I KNEW what kind of valve that was, I just couldn't remember the name. Then when Cad said Symmons, I had an "Aha" moment.
I worked on a bunch of them that dripped really bad (brand new) right after I got started in the trade. We had the manufacturer's rep out, I changed washers, cartridges, & seats, trying to get those darn things to hold.
