What pressure in inches of water column (WC) must liquefied petroleum gas (LPG) maintain from the regulator at the tank?

Liquefied petroleum gas (LPG) must maintain a specific pressure from the regulator at the tank to ensure proper operation of gas appliances. The correct pressure for LPG is 11 inches of water column (WC). This pressure is crucial for optimal function, allowing appliances to operate efficiently and safely.

Maintaining this set pressure ensures that there is a consistent supply of gas to the appliances, which is necessary for proper combustion. A pressure lower than the required level could lead to incomplete combustion, resulting in lower efficiency and potentially dangerous situations due to insufficient heating or incomplete gas burn. Conversely, excessively high pressure could result in safety hazards such as gas leaks or damage to the connected appliances.

The requirement for 11 inches WC is standardized for many LPG systems, ensuring proper performance across a variety of appliances. This standardization helps technicians and installers design, maintain, and troubleshoot LPG equipment effectively.
