I turned off the water at the main cutoff valve in the garage to replace the gaskets in a single handle shower faucet. I got it put back together but when I turned the water back on, I get nothing anywhere in the house. Checked the meter and it is not moving at all. Anyone have any idea what is going on?
Further information. It is a gate valve and I'm pretty sure it's the original that came with the house which is about 17 years old.
