The first valve connects to the entire water plumbing system. Shutting off the meter will cut off the entire water supply to your home or business. To locate this valve  you can consider the following;

Once you know where you shut off valves are, you are likely to be calmer, determine any hazards and risks clearly and act accordingly and prevent any major damage to the premises.

A dual check backflow preventer is similar to a double check valve in operation. It has two independent spring-loaded check valves. However, dual check valves usually do not include shutoff valves, may or may not be equipped with test cocks or ports, and is generally less reliable than a double check valve.[4]

The double check valve assembly is suitable for prevention of back pressure and back siphonage, but is not suitable for high hazard applications. It is commonly used on lawn irrigation, fire sprinkler[2] and combi-boiler systems.[3] If the hazard is higher, even a relatively low hazard such as using antifreeze in the fire sprinkler system, then a more reliable check valve such as a reduced pressure zone device may be mandated.

A double check valve or double check assembly (DCA) is a backflow prevention device designed to protect water supplies from contamination.[1] It is different from the two-way check valves (sometimes erroneously referred to as double check valves) used in air brake systems on heavy trucks which select from the highest pressure source.

The first thing that you should look for is the main shut-off valve. This is the valve that supplies the entire water system in your premises. In most cases, there are two main shut-offs. One connected with the building plumbing system and other one attached to the water meter. Locating each of the two requires different approaches.

Small valves may be so compact as to be barely noticeable particularly when they are integrated into the bodies of existing taps (faucets). Larger check valves may be installed with ball valves at the ends, for isolation and testing. Often, test cocks (very small ball valves) are in place to attach test equipment for evaluating whether the double check assembly is still functional.

It consists of two check valves assembled in series.[2] This employs two operating principles: firstly one check valve will still act, even if the other is jammed wide open. Secondly the closure of one valve reduces the pressure differential across the other, allowing a more reliable seal and avoiding even minor leakage.
