My home was built in the 50's and am pretty sure that my main valve is original to the home. I have shut it off before and noticed that it does not shut the water off completely. Maybe someone could let me know if this particular valve could be replaced meaning the inner workings of it? I see that there is a fitting that looks like it could be unscrewed and was thinking maybe that part was replacable,of course I would need to have the service shut off at the street first.
Also was does the fitting on the side do?
