I was fixing a bathtub faucet problem, went down to the basement, shut off the main water supply, fixed the bathtub problem, and now here is my problem… The main water shut off valve will not open back up. It just keeps turning (not a lever) in both directions. There is nothing that I can find online to deal with this problem. Most of the plumbing emergencies require that you shut off the main water valve, but I am not finding anything that deals with what to do if the valve is the problem. As stated earlier, the wheel just keeps spinning (not freely, but it feels like the same resistance is there no matter how many times I turn it, I have turned it 50 times clockwise, then 100 times counterclockwise and there is no difference). Any suggestions would be appreciated.
