Dive Source requires the following to fill your compressed air cylinder:


  • Diver Certification card or declaration by owner that it is not being used for scuba diving ( ie Paintball)
  • Current hydro stamp
  • Current VIP with a VIP sticker that has a shop name and address on it or the certification number and signature of the inspector.
  • All tanks must be stamped with TC marking (Transport Canada)
  • We choose Not to fill or service Aluminum tanks made from 6351 alloy (typically older than 1988 - see below*)




* 6351 Alloy aluminum tanks: Dive Source and many other shops have chose NOT to fill these tanks as they are prone to developing cracks through a process called sustained load cracking which can develop randomly, between annual service dates. Although rare, there have been 15 serious explosions in north america and frankly we want nothing to do with these tanks anymore. We choose NOT to gamble with our safety or yours and feel the safest and most responsible action is to remove these now 25 year old (or older) cylinders from service and scrap them. 

(This cracking issue does not affect steel tanks.)


Aluminum cylinders made from 6351 alloy include:


  • All aluminum tanks under Special Permit # 6498, 922, 7042, 8107, 8364, 8422
  • All Walter Kidde 3AL Cylinders
  • All Cliff Impact Cylinders Pre July 1990
