Equipment Service and Repair

Manufacturer-recommended service of scuba equipment following manufacturer specification typically includes:

  • Pre-check magnehelic and intermediate pressure to document the regulator baseline

  • Inspect all hoses

  • Complete assembly breakdown into individual components

  • Ultrasonic cleaning

  • Thorough inspection of all components

  • Reassemble each stage using oxygen-compatible Christo-Lube® and genuine manufacturer repair kits

  • Computerized static and dynamic regulator testing of the first and second stages together, and tune for optimal breathing performance consistent with manufacturer specs

  • Submersible pressure gauge check

  • Computer battery change (if applicable), including pressure testing to ensure no leaks

Our manufacturer-recommended service fully complies with OSHA standard 1910.430(a) and Cal/OSHA Title 8 §6057.

Sample regulator service report for scuba repair

Every regulator serviced includes a complete service report showing before and after condition, along with final computerized breathing test results for demand effort vs. flow and venturi performance from our data capture system

A comprehensive computerized testing and data capture process using state-of-the-art Scuba Instruments systems is conducted including flow-rates, magnehelic, intermediate pressure, and quick-set. First we perform static tests to check cracking effort and intermediate pressure. We follow with an extensive suite of dynamic performance tests of the complete regulator (first and second stage), automatically monitored, recorded and logged to files while the regulator is supplying air at varying flow rates. These dynamic tests are important on modern regulators that utilize venturi assists as part of the overall work of breathing. The service report we provide with every regulator service documents Precision Cracking Effort, Static & Dynamic IP Levels, Demand Effort vs. Flow, and Venturi Performance. This article provides additional details about the factors that affect Regulator Performance to provide more background on the tuning we perform during our regulator service.

Be sure to include your low pressure inflator hose when you send in your regulator for service. The o-ring inside the low pressure inflator hose quick disconnect fitting used for BCs and drysuits can dry out, become brittle, and crack, making it difficult to make a good connection. The Schrader valve inside the fitting can wear out and fail. We inspect and test all components, including quick disconnect fittings, clean everything, and replace all worn parts and o-rings.

We return the old parts with each service. All work is warranted for 30 days. Every regulator serviced is tracked in our service database, so we maintain a trend history of your equipment and can provide you with complete details on its health and fully documented service history.
