How to Check for Propane Leak Using the Gas Stop Device

Expert Reply:

When using the GasStop Propane Emergency Shut-Off Safety Valve, # GS24FR and checking for a small leak in the system, the valve should be shut off.

Using GasStop to Test for Minor Leaks:
1. Set up your system as described in your instructions. Turn off the tap on the gas cylinder. Now turn off your gas appliance(s).

2. Now turn the gas cylinder back on. Keep all appliances off for the time being.

3. Pump the pressure gauge on the GasStop up and down steadily at least 4 to 6 times. The longer the distance the gas has to travel in the pipe or hose, the more you will need to pump. If insufficient pressure has been created, the GasStop will keep shutting-off the gas supply. Double check at this point that your appliance is still switched off.

4.The needle on the gauge should now indicate the gas pressure. If the needle is on zero, or below the red bar on the gauge, then the cylinder tap/valve is not open, GasStop has shut-off, the gas has run out or you have not carried out sufficient pumping. Is the temperature around freezing? Please refer to the Useful Tips section in your instruction booklet.

5. Now turn off the tap on the gas cylinder and register the exact position of the needle on the gauge. Wait 60 seconds for Standard Installations and 5 minutes for longer gas systems (e.g RVs).

6. At this point, pressurised gas is now held between the GasStop and your appliance(s).

7. If the needle has dropped from its initial registered position at the end of the recommended period of waiting time, there is a leak (pressure decay). Do not use the gas system until the leak has been solved or repaired by an approved gas specialist.

8. If, after pumping, the needle remains in the same position during the waiting time specified above, you can carefully start using the system.
