12-year hydrostatic testing
Pressure testing and rebuild at the twelve-year mark.

At twelve years the cylinder itself has to be pressure-tested to prove it can still safely hold its charge. Units that pass are rebuilt, recharged and returned. Units that fail get replaced, and we will tell you which is cheaper before we start.
At twelve years the cylinder itself is pressure-tested to prove it can still safely hold a charge. A cylinder that fails is condemned and taken out of service.
Units that pass are rebuilt, recharged, re-tagged and returned. Units that fail get replaced, and we will always price the two options side by side for you first.
This is the step most businesses forget about, and it is the one that most often shows up as a violation during an inspection.
What is included
- Hydrostatic pressure test of the cylinder
- Rebuild and recharge on passing units
- Honest replace-vs-test recommendation
- Loaner units during testing
Questions we get
- Is the twelve-year test really required?
- Yes, for the cylinder types it applies to. NFPA 10 sets the interval and your local authority enforces it.
- Do you take the units away?
- Yes, and we leave certified loaner units in their place so you are never uncovered.
