Thanks NTFDAY. Is it pretty easy to use? I'm guessing you just compress the spring and remove the retainer clip? Any tips or tricks that might be helpful? How do you remve the plastic type retainer on the valve? Thought about just pry'n it off with a screwdriver but figured Id end up jabb'n myself in the hand. My Grandmother lived not far from Springfield before we moved her up here in a little town called Marshfield. I think Springfield is a nice area. I used to spend a week there every summer grow'n up.
