Residential Gas Pressure Testing
Gas pressure testing ensures the gas coming it into the home is at the right pressure. Gas pressure testing requires the temporary installation of a gas pressure gauge. Gas pressure testing requires a permit from your City. Once the testing is completed, an inspection will be performed by the city to ensure everything is correctly restored & safe.
What Natural Gas Is, And How It’s Delivered To Your Home
Methane / Natural gas is a byproduct of decomposing organic matter. Natural gas is predominately methane. Natural gas is colorless, tasteless and (in its natural state) odorless. Utility companies add a distinctive odorant to identify natural gas leaks.
Natural gas delivers to your home by pipeline. Compressor stations move the gas through major pipelines at 750 psi (pounds per square inch). The major gas pipelines deliver the gas to your local utility’s gas-supply grid. There, the gas pressure is regulated down and fed into the gas distribution system. Next, individual service lines deliver gas to the structures. As gas enters your home, its pressure is typically around .25 psi (1/4 of 1 pound).
There is a regulator beside the gas meter to control the gas pressure coming into your home. The regulator is typically round. The Gas-Pressure Regulator is designed to shut off the gas flow (coming into the house) when no gas is being used. When gas is needed, the regulator opens just enough to allow that amount of gas through.
The regulator can adjust to any level of gas demand at any given time. The regulator can be adjusted to allow more or less gas into the house, based on the number of gas burning devices. Since any home can have one or more gas-fired devices (furnace, water heater, fireplace, clothes dryer, & gas cooking appliances) the gas pressure is adjusted to accommodate all devices that exist.

Once the gas is inside your home, the nozzles inside gas burning devices are designed to permit a specific gas flow at a specific gas pressure. Too much gas pressure means too much gas flow. Too much gas flowing into your furnace causes more heat to be generated than the furnace is designed for. If your furnace fan and exhaust flue cannot carry the heat away fast enough, the furnace will overheat and shut down to protect itself and you.
There is a risk of fire from any gas-fired device overheating due to too much gas flowing into it. For this reason, gas burning devices have their own gas regulator. If the gas pressure is too high, the regulator shuts off all gas coming into the device, such as a furnace (as a safety feature). Though the furnace’s regulator stops the risk of overheating, it also shuts the furnace down.
Gas Pressure Testing
A Gas Pressure Test Requires A Permit From Your City. A city official perform an inspection to ensure everything is up to code and safe. Once inspected & approved, the temporary meter is removed and the gas can be turned back on.
WARNING: Improper Inspection & Testing Methods Involving Gas Pressure Create Dangerous Conditions And The Risk Of A Gas Explosion. 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.

Gas pressure determines how fast gas can flow into a gas-burning device. While gas devices have the ability to regulate if gas pressure coming in is too high, they often don’t have the ability to deal with gas pressure that’s too low. If the gas pressure is too low, it may affect the ability of gas burning device to operate correctly. In that case, the devices will shut down to protect themselves and your home.
It’s very important the gas pressure entering the home and each gas device is correct. Gas pressure testing ensures the right pressure coming into the home or a specific gas-burning device. Once testing is completed, a city official will perform an inspection to ensure everything is up to code and safe. Once inspected & approved, the gas can be turned back on.

WHAT HAPPENS IF GAS PRESSURE IS TOO HIGH
The nozzles in the gas fired devices in your home are sized to permit a specific gas flow at a specific gas pressure. Too much gas pressure means too much gas flow. Too much gas flowing into your furnace causes more heat to be generated than the furnace is designed for.WHAT HAPPENS IF GAS PRESSURE IS TOO LOW
If gas pressure is too low, the gas-fired device can’t work properly and will shut down. There are many safety devices to protect gas burning devices in the event gas pressure is too high or too low. Gas furnaces all have a “Flame Sensor”. If the Flame Sensor cannot determine that a proper flame exists when gas is flowing, it shuts the gas off to the burners. If gas pressure is too low, the flame will be too small for the Flame Sensor’s requirements and the furnace will shut down to protect itself, you & your home.
