SCUBA Tank Hydrostatic Testing
A tiny compliance shop hiding inside every dive market
Bottom line
Worth studying, but do not buy without strong local proof.
SCUBA tank hydrostatic testing shops inspect and pressure-test dive cylinders so they remain legal and safe to fill. The niche is small, but it has a useful compliance cadence: visual inspections are typically annual, while hydrostatic testing is required every five years for many cylinders. Dive shops, fire equipment shops, paintball operators, and commercial divers all need reliable turnaround.
How It Works
Customers or dive shops drop off cylinders. The operator performs visual inspections, valve service, eddy testing when needed, hydrostatic pressure testing, stamping/documentation, and optional air fills. Revenue is per tank, with extra fees for cleaning, valves, tumbling, paintball cylinders, and expedited turnaround.
