The main line immediately leads to water ready for cold water use. There's an additional step for hot water. It's where the water supply leads to the water heater, leading to water taps, showers, and other hot-water appliances in the house.
The cold water service line slopes away from the water heater after splitting from the main line. Cold water service lines run directly to every water fixture and appliance in your home. Plumbers install these pipes in straight lines, 90-degree angles, or slight downward slopes to facilitate easier flow.
The main water line usually comes through the basement concrete floor or wall. In some cases, the main water could enter through a different area, such as near the furnace or water heater. In crawl spaces with a basement: It can be found where water enters the basement.
DIP TUBE – This is the tube where water enters into the tank to replenish the hot water being used. It's located at the top of the tank and goes down to the bottom where the water is then heated.
In most cases, the valve is connected to a copper pipe beside the water heater. Since your water heater isn't in the crawl space, it's probably in a utility closet on the main floor. After you've exhausted all options but still haven't find the main valve, read the inspection report you got when you bought the home.
Once inside the house, the main water supply line/pipe supplies all plumbing fixtures, and likewise supplies water for your water heater. However, after the water connects to the water heater, the main water supply line splits into hot and cold water pipe paths – referred to as the cold and hot service lines.
Main Water Shut-Off Valve Basics and Importance
Most homes actually have two such valves: One for outside water sources, which is generally controlled by the city you live in, plus one for your indoor plumbing and water areas.
If the inlet and outlet pipes are reversed on the water heater, the functionality of the heater will be impaired. The system relies on a specific flow of water - cold water enters through the inlet pipe and gets heated, then hot water exits through the outlet pipe. By swapping these pipes, you disrupt this flow.
Who is Responsible for the Water Line From the Street to Your House? Water service lines within the bounds of your property are considered your personal responsibility to maintain, while public water pipes outside of private property lines are the city's responsibility.

This pipe, called the water or supply line, carries water from the mainline to your house. The supply line is buried deep enough underneath the property that it won't freeze, and it runs from the ground directly into the home. Supply lines are usually made of plastic, galvanized iron, or (ideally) copper.
The short answer is yes, as long as you don't mind using cold water. Shutting off the input to your water heater will not affect your home's main water supply. You can still run appliances like your washing machine or dishwasher, flush your toilet, and use your shower, sink, or garden hose.
In most cases, it's not advisable to continue using water if your water heater is leaking. While you may be able to run cold water, using hot water from a leaking unit can cause further damage to your plumbing system and potentially lead to safety hazards.

In rare cases, the city water main may be located under the sidewalk, but the same rules still apply under this definition.
Next, in the house, the main water connects to the water heater. At the water heater, the water line splits in two. One branches off for cold water, while the other stays connected for hot water. The cold water line splits from the water heater, and directly has connections to each water appliance.
Backdrafting is when the exhaust gases from your water heater, rather than safely leaving the house via the vent, spill back into your house. These exhaust gases contain carbon monoxide and moisture. This action is considered dangerous and should be rectified as soon as the homeowner discovers it.
They are very different, and if you hook it up backwards, it won't work very well. The cold water has a dip tube that reaches almost to the bottom of the tank. The hot connection is at the top. If you add cold water to the top, the water drawn from the bottom will be cooler than expected.
The water valve Inside your house is your property. No one can sue you for turning that one off. The valve in the street or meter pit for your house belongs to the water utility. You could have to pay for the repairs if you damaged it.
