Where should shutoff valves be installed in relation to a building?

Shutoff valves should typically be installed at the entrance to the building to ensure that they are easily accessible for maintenance or emergency situations. This location allows for a quick way to stop the flow of fluids into the entire system, making it essential in cases of leaks or repairs.

Installing valves at the entrance also aligns with code requirements that prioritize safety and accessibility, ensuring that anyone can reach the valve without having to navigate further into the building or against the flow of the piping system. It ensures that the entire system can be shut off quickly, which is crucial for safety in case of a gas leak or a water main break.

While there are other locations where shutoff valves can be placed, such as near appliances or directly next to tanks, these locations may not provide the optimal accessibility needed in urgent situations. Therefore, placing the shutoff valves at the building entrance is the best practice, facilitating safety and compliance with code regulations.
