Once you&#;ve recorded your numbers, you have a couple easy ways to submit them to Texas Gas Service.
If you are concerned about the accuracy of your meter, we will come and check it. The first test is free of charge. We will remove the meter, replace it and test it. If the test indicates that the meter is not functioning accurately, we will adjust your bill. The acceptable range of accuracy for a natural gas meter is established at 2%, fast or slow. If, after the first test, you still believe that the meter is not functioning properly, you may request additional testing. However, if we test the meter and it is found to be within the acceptable range of accuracy, you will be charged a fee for this second test.

If you pump the gas line against the meter, even with the meter off, you run a risk of damaging the meter. Natural gas runs on very low pressure. 15 psi against the mechanisms of the meter can cause plenty of trouble. The method is to disconnect the pipe at the meter. Put the test gauge on there and pump it. (I always plug all ends of the gas lines too with plugs, not just gas cocks) In Washington, our test gauge must be of the 15 psi scale. (max of 15 psi) The test must hold for 10 minutes when the inspector arrives. I usually pump to 10 psi.
Remember that if you pump the line when the outside temperature is higher than when they do the inspection, the pressure will naturally be lower due expansion and contraction. I always beat the inspector to the jobsite on inspection day and pump the line to perfection about 20 minutes before his arrival.
