How do I get the bottom half of the faucet stem out?
Due to a leaky bathtub faucet I have to replace the seat on one of the faucet stems but I can't get the bottom half of the stem out. It's a Valley II faucet assembly that was most likely manufactured in the 80s. I tried unscrewing the grooved pipe but no matter how many times I turn it the pipe doesn't come out any further. Pictures are linked below. Any suggests on getting this thing out?
