Step 1 of Equipment Servicing
Most equipment manufacturer's specification for working pressure of between 120 PSI to 150 PSI, so if your unit is above the upper range, it could free flow from the second stage.

This is due to the high pressure (HP) seat in the first stage of the regulator being worn out through regular wear and tear, which is why it needs to be replaced annually.

Next, we examine the 2nd stage of the regulator, using a Magnehelic gauge to check the breathing effort of both primary and alternate 2nd stages. Manufacturer's specification of between 1.0 to 1.6 inch breathing effort and between 2.0 to 2.5 inch respectively.

Without the Magnehelic gauge and IP pressure gauge manager, the above check CANNOT be performed.

Next, the regulator unit, with an air tank connected, goes into a water tank for an in-water pressure test. This is the only reliable way that bubbles can be detected. Based on this, we would be able to recommend to you what needs to be done for your regulator.

Step 2 : Servicing The 1st Stage
All parts of the 1st Stage of your regulator will be disassembled with proper, customised tools. Most quality regulators require special tools for proper disassembly, so naturally, we carry most of these specialised precision tools to make sure that your regulator is not damaged during disassembly and reassembly.

Next, the disassembled parts of the regulator 1st stage will be placed in an ultrasonic cleaner for degreasing and salt deposit descaling.

For this, we use special chemicals recommended by the manufacturer of your regulator that are harmless to all regulators, specifically with regards to materials such as brass, plastic and rubber.

We do NOT use vinegar or any other fluids not recommended by your regulator manufacturer as these may damage your regulator's interior and exterior. Chrome parts are especially vulnerable

After the ultrasonic cleaning, all parts will be free from grease / salt deposit, and the regulator should look as good as new.

All O-rings and parts for the HP seat will be replaced even if they appear to still be in good condition. This is highly recommended for annual servicing.

After this, the 1st stage will be reassemble for a second IP pressure testing to make sure it complies with the Manufacturer's specification, we proceed to service the 2nd stages

Step 3 : Servicing The 2nd Stage
As with the 1st stage, all parts of your 2nd stage will be disassembled with proper tools, before being placed in the ultrasonic cleaner for cleaning.


The diaphragm of your second stages will then be inspected to make sure there are no perforations that would allow water to trickle in a 2nd stage is breathed during a dive. If perforations are detected, we will email the pictures to you for replacement approval

All O-rings and parts for the low pressure (LP) seat will be replaced, even if they still appear to be in good condition, after which the 2nd stages will be reassemble for breathing effort tuning.

After this check, your primary 2nd stage will be adjusted and tune to a breathing effort rate of between 1.0 to 1.6 inch breathing effort.
Note: This cannot be done without the Magnehelic gauge Tester!

Step 4 : Servicing Alternate Air Source (Optional)
As with the 1st stage & 2nd stage, all parts of your alternate air source will be disassembled with proper tools, before being placed in the ultrasonic cleaner for cleaning.

All O-rings and parts for the low pressure (LP) seat will be replaced, even if they still appear to be in good condition, after which the 2nd stages will be reassemble for breathing effort tuning.

After this check, your alternate air source will be adjusted and tune to a breathing effort rate of between 2.0 to 2.5 inch breathing effort. (Depending on the model specification)

Note: This cannot be done without the Magnehelic gauge Tester!

Step 5 : Servicing Gauges (Optional)
We will replace the 2 O-rings to prevent leakage between the hose and pressure gauge, as well as perform a chamber test for the depth gauge to determine if it can accurately measure depth.

Once this is completed, your entire regulator unit would have been serviced.

Before our service technician signs off on your regulator unit, we will immerse it for another water pressure test to double-check that there are no leaks. If no leaks are observed, the service process is completed, and your unit will be ready for collection.

We never use silicone only Christolube and everything comes out clean for nitrox service.
