I have frost-free spigot that developed a leak this summer that comes from the handle only when the water is on. After trying to fix the problem then turning on the spigot without a handle, it appears the water is coming through the rod itself. How can I fix it?
I think the spigot is some model of B&K Mueller Quartermaster.
I assumed the problem was with a thick rubber washer at the location labeled B. I wasn't able to get a replacement at the hardware store, but the guy suggested to use some "valve packing cord" next to it instead to increase the pressure on the washer so it would seal better, but that didn't work. It appears the water is coming through the rod, not around the area where that washer seals (see the second picture where I totally removed that part).
There's also a weird plastic washer (labeled A) with a soft plastic sealing material on one end. That sealing material has a piece missing, but I'm not sure what that part is doing or if that matters. Or even what it's called to find a replacement.
Here are some pictures:
The end of the rot that connects to the valve looks solid.
