Yes, older houses almost always have water shut-off valves, but they can be significantly harder to locate or operate than those in modern homes. The main indoor valve is typically located in the basement, a crawlspace, or a utility room near where the main water pipe enters the house.
The average cost to replace a main water shut-off valve is $250 to $600, with most homeowners spending around $425 for the materials and labor. Water main shut-off valve replacement cost depends on the valve type, material, and location, with prices often in the thousands if the valve is buried or difficult to access.
No. Some homes have a shut-off valve homeowners can access inside, while the water meter valve located outside is used by the utility company.
Yes, turning off the water does not prevent pipes from freezing. If the water inside the plumbing drops below freezing, it will still expand and can burst the pipe. However, shutting off the water stops continuous flooding and minimizes damage if a pipe does crack.

There is no universal location for your home water shutoff valve. However, the location is likely dependent on your water source: Inside your house, likely on a wall on the street side of your house. In warmer climates, outside your home near an outside faucet.
It can look like a round handle (gate valve), a lever-style handle (ball valve), or a small oval knob (angle stop valve). The main shutoff is often larger and located near where water enters the house.
There should be a valve on each side of the water meter. Either valve will shut off the water to your home if they are operable. Care and maintenance of these valves is the responsibilty of the homeowner.
A standard ball valve replacement takes 1 to 2 hours. If the valve is difficult to access, it may take longer.
Knowing When to Replace Shut-Off Valves
You should replace shut-off valves in your home roughly every 10 to 15 years. But you should do it sooner if you notice leaks, corrosion, or difficulty turning them. These small but critical devices control the water flow to sinks, toilets, washing machines, and other fixtures.
The main water shut-off valve is typically located where the main water line enters your home. Common locations depend on your climate and home layout:

Most houses, apartments, condominiums, and businesses have a water shutoff valve, commonly referred to as a master valve or house valve, that turns water off throughout your home or business.
Finding the Main Water Valve: The main water shut-off valve can be inside the house (often in basements, crawlspaces, or near the water heater) or outside (buried near the street under a metal cover labeled "water meter"). Turning Off the Main Water Line: To turn off the inside valve, simply twist it clockwise by hand.
some houses don't have shutoffs on each outside spigot. they'll have frost free bibs that are ok (disconnect hoses before it freezes). but there should be a house shutoff. But i've heard of cases where there weren't.
The bottom is to shut off water from the street. The top one is to keep the water in your house pipes from backing up and draining when you remove the meter for service or replacement. Oh and to answer your question you can shut off either or both. The Main being the bottom one.

The main water shutoff valve is typically located where the main water line enters your home. In colder regions, this is usually on an interior wall in a basement or crawlspace facing the street. In warmer climates, it may be outside near an outdoor faucet or inside a utility room/garage.
Your main water shut-off valve is typically located on the perimeter of your house, usually on the side closest to the street. Common indoor spots include your basement or crawl space, garage, or near the water heater. In warm climates, it may be outside near an exterior faucet.
Yes, you should open your faucets immediately after turning off your main water supply.
An often-overlooked sign of burst pipes is the sound they make. If you hear dripping sounds, hissing, or a distinct rushing water sound within your walls, it's a clear sign of a plumbing problem. These sounds indicate that water is escaping from your pipes and flowing into areas where it shouldn't be.
