Shut off valves are installed to give homeowners the ability to turn water off to individual fixtures in their homes. Some older homes or newer bathrooms and kitchens with sub-par renovations contain few or none of these valves, making repairs and replacements a much more difficult process. My Favorite Plumber can install valves as part of an individual project, water-line upgrade or whole-room redo.

Of course, any valve in your home that has a drip or similar malfunction should be replaced immediately.
