In scenarios where gas piping supplies more than one building on a premises, it is essential to have temperature and pressure relief valves installed. These valves are a critical safety feature designed to prevent excessive pressure buildup within the gas piping system.

When gas is supplied to multiple buildings, fluctuations in temperature and pressure can occur due to varying demands from different structures. Without an appropriate mechanism to relieve these pressures, there could be a risk of leaks or potentially dangerous blowouts, which could lead to severe safety hazards, including fires or explosions.

Each building may have different requirements in terms of gas usage, which can affect the overall pressure in the piping system. In order to ensure the safety and integrity of the gas supply network, installing temperature and pressure relief valves is a fundamental requirement dictated by safety codes and regulations within plumbing practices.

This showcases the importance of having proper pressure regulation in gas systems, particularly when configuring installations for multiple buildings. The other options, although relevant in various contexts, do not specifically address the critical need for pressure management in this particular scenario.
