I need to turn off my water at the curb to replace my shut-off valve in the house (my water meter is in the house, not buried outside). I bought a wrench silmilar to this one: http://www.gunk.com/product_images/SM_194.JPG but when I opened the hex nut on the cover outside at the curb I find that I have access to a 1 1/2 inch metal conduit or tube that has a small metal rod (less than 1/2 inch diameter) that seems to extend into that tube about 15 inches below ground level. It's hard to explain exactly what it looks like but needless to say, the wrench I bought does not fit down this narrow opening nor would it seem to do any good if it did as it doesn't seem that this metal rod would turn. It must need to be pushed down, pulled up, or pushed in, the nearest I can figure. Does anyone know how this shut off works? The cover on it says QSP water, if that's a help.
I know I can call the water company, but they will charge $50 to turn it off and on and will only do it during business hours and I need to make the repair in the evening or weekends. (and this is New Jersey, so don't even suggest I call a plumber).
