How a scuba equipment servicing is carried out
Step 1 => Contact us via WhatsApp or email with the details of the equipment to be serviced or repaired.
Step 2 => Drop off your equipment at our workshop, arrange a collection point, or organize shipping by mail.
Step 3 => We inspect, service, and test your equipment before confirming any billing.
Step 4 => We return your equipment with a service report and a 1‑year warranty.
Safety and Warranty
Our Quality Commitment
Each serviced piece of equipment is tested before being returned.
We use replacement parts specific to each major brand of diving gear.
Our one‑year warranty covers all work carried out during the servicing.

The annual regulator servicing is recommended by PADI and all major diving federations.
A properly maintained regulator delivers a constant airflow and reduces the risk of leaks or free‑flow underwater.
A faulty purge or inflator on a buoyancy control device (BCD) is a common cause of loss of buoyancy control.
We document every intervention to allow dive centers to maintain an accurate and compliant maintenance log.
Service Areas
Scuba Equipment Servicing in the Andaman Sea
Our scuba equipment servicing and repair workshop is based in Krabi Town, Southern Thailand.
We provide services for divers and dive centers in Koh Phi Phi, Krabi, Ao Nang, Koh Lanta, and Phuket.
Delivery is available for all dive operations across the Andaman Sea.
For individual divers staying in Krabi Town, we offer a collection service directly from your accommodation, with same‑day return of your serviced equipment.
We also accept mail shipments from other regions of Thailand.
Everything You Need to Know About Scuba Equipment Servicing and Maintenance
Scuba Regulator Servicing

The scuba regulator reduces the high pressure from the tank to ambient pressure, allowing the diver to breathe.
The first stage connects to the tank valve and lowers the high pressure to intermediate pressure = ambient pressure + 8 to 10 bar (depending on the regulator).
The second stage reduces this intermediate pressure to ambient pressure on demand, with each inhalation by the diver.
The octopus is a secondary stage used as an alternative air source in case of an air supply failure.

Scuba regulator servicing includes complete disassembly, ultrasonic cleaning, replacement of O‑rings and seats, spring inspection, reassembly, and pressurized breathing tests.
Manufacturers such as Scubapro, Aqualung, Apeks, Mares, Cressi, and Sherwood recommend servicing annually or after 100 dives.
A regulator that is not properly maintained may develop air leaks, uncontrolled free‑flow, or increased breathing resistance, all of which represent serious risks while diving.
BCD Servicing and Repair
The buoyancy control device (BCD) allows divers to achieve neutral buoyancy at any depth by adding or releasing air.
The inflator mechanism is connected to the low‑pressure hose and controls inflation and deflation of the BCD.
A faulty inflator can cause uncontrolled ascent or inability to release air, which is a serious hazard underwater.
The BCD’s quick‑dump valves release air from the bladder and must be perfectly sealed to prevent unwanted deflation during the dive.
BCD servicing includes cleaning the inflator, replacing O‑rings, bladder leak testing, and verifying the proper function of all quick‑dump valves.
Dive Computer and Pressure Gauge Servicing
The dive computer measures depth, bottom time, ascent rate, and nitrogen saturation to calculate real‑time decompression limits.
Battery replacement in a dive computer or dive watch requires careful installation of the sealing O‑ring to maintain the manufacturer’s specified waterproof rating.
The pressure gauge indicates the remaining cylinder pressure and must provide accurate readings to avoid any risk of running out of air underwater.
Servicing the pressure gauge includes O‑ring replacement and a pressurized leak test under operating conditions.
Regulator Hose Replacement

Medium‑pressure hoses connect the first stage to the second stage, the octopus, the direct system, and the drysuit inflator. High‑pressure hoses carry higher intermediate pressure and supply air‑integrated consoles or SPG gauges.
Cracked or worn hoses are a frequent cause of air leaks and must be replaced before any failure occurs underwater.
Why Service Your Scuba Equipment in Thailand
The Andaman Sea’s warm water and tropical conditions accelerate the wear of seals and membranes.
Salt, sand, and humidity degrade O‑rings and regulator components faster than in temperate waters.
Servicing with Siam Underwater Tech ensures your equipment is maintained by an experienced technician.
Dive centers in Southern Thailand that regularly service their gear experience fewer equipment failures and greater operational availability.
Siam Underwater Tech provides scuba equipment servicing and repair in Southern Thailand, covering Koh Phi Phi, Krabi, Ao Nang, Koh Lanta, and Phuket.
We service regulators, BCDs, inflators, quick‑dump valves, pressure gauges, and dive computers for both individual divers and dive center fleets.
All major brands are accepted, including Scubapro, Aqualung, Apeks, Mares, Cressi, Sherwood, Suunto, and Oceanic.
For divers staying in Krabi Town, we offer a hotel collection service with half‑day return.
