I have 2 cylinders (232bar) that needs to be checked and hydro tested. Any idea where I can take them - easiest/cheapest options?
It is indeed Oom Jaap Barnard in Valhalla @ 012 6600950
But for the effort it is most probably better for you to take it to your nearest scuba shop and pay them the few extra bob.
I took mine to Calypso divers in Cresta. I waited a week or so and they charged me R154 wall&all for the Hydro check, refill and service. which is fair.
