Regulator Service

A typical regulator set has 3 stages, and each requires periodic service based on the manufacturer’s individual recommendations. Most manufacturers suggest annual service.

Typical annual service includes a full overhaul of each stage of the regulator and includes chemical ultrasonic cleaning. Once fully disassemble, all consumable parts must be changed. Parts are extra unless covered under manufacturer warranty. Parts kit prices vary by manufacturer, but average $30 per stage.

Not sure if your regulator is behaving correctly? We can do a performance test on the cracking pressures of your second stages and intermediate pressure of your first stage to ensure accurate performance.

Annual service: $40 per stage

Oxygen cleaning: +$10 per stage (O2 safe parts kits may be more expensive)

Regulator Performance Test: $15 per stage

HP Spool overhaul: $15

RUSH Surcharges:

Customers needing rush service on regulators can pay a surcharge to ensure either:

24 hour service: $100

48 hour service: $60

Rush service is dependant on parts availability. We stock most parts for all the regulators we service and can confirm availability ahead of time.

Dive Computers

We sell a wide variety of stand-alone battery kits for computers by Mares, Suunto, Oceanic, Shearwater, Cressi and more. Battery kits are useful spare parts, and many batteries are user changeable. Care must be taken when changing your own batteries as you risk flooding and permanently destroying your computer. In some cases, changing your own battery may void the manufacturer warranty. AquaSub accepts no liability for computers that flood when a user has changed their own battery.

We also offer battery change & pressure test for leaks and sensor accuracy in our pressure tank. We test in fresh water and should a computer flood, in most cases it can be dried out and repaired however because we cannot be certain of a computers status before it enters the shop, we will so not accept liability for damages that cannot be repaired in-house or under warranty.

Standard Computers: $44 (plus battery kit)
Watch style: $95 (plus battery kit)
