Where can you find the valve to turn water off while replacing bathtub faucet?
Generally, you will need to cut the main water supply. This is normally in the front lawn, inside of a steel box. If you have a basement, it may be there. The main valve is square shaped and requires a tool called a water key. It is a long T shaped wrench. These can be bought at some hardware stores for $10 to $15. The other option would be to call the city Water Works. They will generally shut it off and back on, free of charge. I hope this helps.
