What is the normal gas pressure inside a customer's home?

• A. 3" w.c. or 1/8 psi
• B. 5" w.c. or 1/6 psi
• C. 7" w.c. or 1/4 psi
• D. 10" w.c. or 1/2 psi

Answer: (C)

The normal gas pressure inside a customer's home is typically around 7 inches of water column (in w.c.), which is equivalent to about 1/4 psi. This pressure is considered standard for household gas appliances to ensure safe and efficient operation. Maintaining this specific pressure is crucial as it provides the right balance for proper combustion in appliances like furnaces, water heaters, and stoves. Gas pressure that is too low may lead to inefficient appliance performance, while pressure that is too high can create safety hazards, such as increased risk of leaks or even explosions. Therefore, ensuring that the gas pressure remains at around 7 inches w.c. is important for both safety and functionality in residential applications.
