If it reads less than 2/3 of stated pressure, it may be worth returning the cylinder to your local stockist for us to check.

All gas cylinders require a HSE test usually every 10 years, an industry standard 'test ring' is located around the cylinder valve which shows when it should next be tested. Cylinders are safe to use after the date has passed, but they won't be refilled after being returned to us until they have been retested by one of our accredited test centres.

Perform a check on your system for leaks, if a leak cannot be found it may be that you have your flow rate set too high. Make sure you turn the cylinder off by its valve when you are finished using it, as even a small leak can empty your cylinder over time.
