Are city water meters equipped with check valves?

Is it possible to have water meters without return valves?

A non-return valve can be fitted in conjunction with an internal water meter installation. However, many meters do not include one or other modifications to the water supply pipes.

Do water meters prevent backflow, in addition to the above? These backflow-prevention devices must be placed as close to the water meter as possible. This helps to eliminate the possibility of an illegal connection between your meter, backflow device and your meter.

Also, where is the watermeter usually located?

Although your water meter is usually located at the curb in front your home, it can also be in your basement in certain areas. The outside meters are usually housed in a concrete box marked "water" as shown in the photograph or in a pit with a cast-iron lid.

Do I really need a check valve to keep my water from leaking?

All submersible pumps must have check valves. They allow water to flow in one direction. They prevent water from leaking back into the well through the pressure tank and column above the pump.
