If you’re happy that it’s been sealed all that time and it’s only gunk, rust etc on the regulator then you can submit it for testing as is and get a new regulator included in a slightly higher price.Thanks mate not sure I can get mine tested anyways! And think I need a new reg I’ve dug through the old kit bag and the reg looks a bit dodgy
The combined price would tend to be cheaper than a regulator and a test seperately
Note that the actual hydro test is the cylinder only, not the regulator
