Do You Need to Pressure Test Natural Gas Lines?

All gas piping in the Colorado Springs area must be tested by something known as a “pressure drop test”.  This requires the use of a manometer or water column gauge.  You don’t happen to have one in your garage do you?  A very small amount of pressure is inserted in the piping system, then it is monitored to detect the pressure drop.

The next question is…should you cap off the lines before the shutoff valves to avoid stressing valves, but not test them, or should you close the shutoff valves and remove the caps on the traps so that excess pressure leaking through valves would be vented instead of damaging the appliance regulators?

This is beyond your pay grade isn’t it?  In the Colorado Springs area, you should call Altitude Heating and Air to have your gas lines pressure tested.  It is just another of the many services that they offer to keep the Colorado Springs’ area free from plumbing and gas line problems.  Call Altitude Heating and Air at (719) 209-4955.
