Acceptable Gas Line Pressure Drop
In order to pass gas line pressure tests, lines must hold a specific psi for the length of time mandated by local codes. When testing for leaks, there will be some natural rises and drops in the pressure of the gas line.
How to Pressure Test a Gas Line
Before you pressure test a gas line, complete a walkthrough. Refer to the piping system schematic and make sure no ends are left open. All joints and connections should be exposed for evaluation. Any parts of the piping system that are not part of the test should be properly isolated, and necessary lockout tagout measures should be complete.

What is gas pressure test?
Gas pressure testing ensures the gas coming it into the home is at the right pressure and is done at the gas meter and requires the temporary installation of a gas pressure gauge.
How much pressure does gas have?
As gas enters your home, its pressure is typically around .25 psi (pounds per square inch) or 1/4 of 1 pound of pressure.
What does it mean when a furnace has too much gas?
Too much gas pressure means too much gas flow. Too much gas flowing into your furnace causes more heat generated than the furnace is designed to generate. If your furnace fan and exhaust flue cannot carry the heat away fast enough, the furnace will overheat, which is also true of your gas water heater and gas clothes dryer.
What is the gas regulator on a gas meter?
There is a gas-regulator beside the gas meter to control the gas pressure coming into your home. The regulator is typically round.
Why is gas pressure important?
Why Gas Pressure Is Important. Methane gas is a byproduct of decomposing organic matter. If you pass a landfill, you may see pipes with flames, which is the methane gas (generated by the landfill) burning. Natural gas is predominately methane. Natural gas is colorless, tasteless and (in its natural state) odorless.
What is the purpose of a gas permit?
A trained technician must perform all gas pressure testing. The purpose of the city permit is to ensure the technician doing the test is qualified. Additionally, their work is inspected by a city inspector.
How does natural gas get to you?
Natural gas delivers to you by pipeline. Compressor stations move the gas through pipelines at approximately 750 psi (pounds per square inch). These gas pipelines deliver the gas to your utility’s gas-supply grid.
Why do gas lines need to be pressure tested?
Gas lines provide critical functions to individual homes and sometimes to entire towns or cities. They must be properly maintained and managed to prevent damage or a loss of service . Pressure testing is one of the most common ways of testing a line’s integrity.
Why do you need to test gas lines?
All gas lines must be maintained and examined regularly. Piping problems can cause a variety of issues including leaks and line damage. Gas pressure testing helps stop these problems before they occur.
Why is gas pressure important?
One of the most important is gas pressure. If a gas line experiences too much pressure, it could suffer severe damage and/or leaks. Gas pressure testing serves as a method of ensuring that the line can stand up to high levels of force. Read our guide to learn all you need to know about gas, including how to test its pressure levels.
What are the laws of gas?
It’s used to determine how a gas relates to its environment. All other gas laws are simple gas laws. They include Boyle’s, Charles’, Avogadro’s, and Amontons’ Law. Boyle’s Law describes how the pressure and temperature of a gas relate when the temperature and amount of gas remain constant. Charles’ Law describes the relationship between volume ...
How many homes are heated with natural gas?

What are the variables that determine the condition of a gas?
Five variables determine the condition of a gas; pressure, volume, temperature, the amount of gas, and a gas constant written as the letter R. Temperature is measured in Kelvin, and the amount of gas is measured in moles. Each of these variables affects gas pressure. More moles of gas and higher temperatures cause it to increase.
Which conditions make a real gas behave like an ideal gas?
Which conditions make a real gas behave like an ideal gas? The higher the temperature and the lower the pressure, the more ideal a gas will become.
Why does my fuel system lose pressure?
Fuel systems can lose pressure for a variety of reasons, but if the odor of fuel is evident around the vehicle or under the hood, the likely issue is a fuel leak. Vehicles with fuel leaks should never be driven, as this poses a distinct risk of fires, especially if the leak is in the engine bay.
How does a fuel system work?
The fuel system for all types of vehicle operates by pumping fuel from the fuel tank, sending that pressurized fuel through fuel lines, regulating the pressure, and circulating unused fuel. Since the entire system must be pressurized to function properly, when a fuel system has lost pressure it will surely fail.
What happens if fuel delivery is not delivered?
If fuel delivery is lacking, this will result in a lean running condition, which can generate enough heat to cause engine or exhaust manifold damage, especially on turbocharged vehicles. Fuel system issues should be inspected and repaired immediately, and will likely prevent operation.
What is the purpose of a fuel pump?
The fuel system may have a mechanical fuel pump to create very high pressure in the fuel system , which is the case for diesel vehicles and many performance based gasoline engines. For diesel vehicles, the fuel will first run through a fuel and water separator to remove water from the fuel.
Do gasoline vehicles use high pressure fuel pumps?
Most gasoline vehicles do not use the high pressure fuel pump, and will simply route pressurized fuel through a fuel pressure regulator, fuel rail, and fuel injector (s). In both cases, this provides several locations to be tested for fuel pressure testing.
