Air Cylinder Filling Services

Surface-use-only valves only need to be tested every five years (a full, hydrostatic test). If your valve has a pre-fitted gauge like the one pictured below, then you have a 'Surface use only' bottle. Most dive centres can offer a full hydrostatic test from around £40.00 Inc VAT.













Those bottle with valves which could be used underwater for diving - regardless of whether they are or not - need to be tested every two-and-a-half years. There will be no guage on the side of the valve in this instance. It will be in-line.


Surface only bottles will often last a very long time as they do not suffer from any salt corrosion.
