Ok, thanks for the help for the shutoff valve and the question about replacing the pipes. Last night, my wife pointed out to me that there is a drip at the bottom of the main supply line (?) This pipe is coming from inside the house and at the bottom of it there is a release nut/valve (Same thing as on the Febco 765 Poppet Assembly) I am sorry for all the wrong terminology and such as I am a newbie to this.
