Just a quick note to publicly praise NDAC Chepstow.

I recently bought 2 cylinders from an internet dive shop (mention no names) and decided to take them for a test run.

After having them filled, the 12litre O2 Clean cylinder was leaking from the neck!!

The young chappie from NDAC said that it was probably a wrong size O ring and would have a look for me. It was, and he fixed it for a fiver.

I know NDAC has come in for some critisism in the past, but I have been there several times and they have always been really good.
