Can I remove the tube from where the faucet is, I have no access from the inside or outside of my house. The water leaks from behind the siding when the faucet is on and water pressure is applied. It must have freezed, the stem and "front" seal are already out, now how to remove the tube??? I'm sure glad some of you guys and gals like these valves, as I'm 3 problems from only 3 valves. Any help would be great, thanks.
