Repairs & Service. Where the Certified Technicians are at their best!

Len Curtin serviving regulators

Here is where the precisely machined parts, silicone and o-rings, valves and regulators come together so that we can enjoy the underwater world we love so much.

Your regulator could be the most important piece of equipment you own and should at least be serviced annually. Many of today's Manufactures offer a lifetime warranty on parts as long as you have the equipment serviced regularly. Here is an explanation of what this service consists of.

Here at the repair bench regulators, alternate air sources, and gauge consoles are disassembled down to the last o-ring.. Next they are given a cleaning bath to remove any corrosion from the parts. The parts are then dried, inspected, and polished. O-rings, seats, gaskets, and other soft parts are replaced, lubricated, and re-installed. The equipment is then assembled and re-tuned to factory specifications. Every piece of equipment is then water tested for leaks by submerging it in our test tank.

Whether you dive once or twice a season or your in the water every weekend. Your equipment should be serviced at least once a year to keep it performing well.

Buoyancy Compensators
Your BCD should be serviced annually to check for leaks, corrosion, salt build up, and proper function. Here is an explanation on what is done. First your power inflator is removed from your BCD. It is disassembled and given a cleaning bath removing any corrosion. O-rings and soft parts are replaced and the power inflator is reassembled and tuned to factory specifications. Next the BCD is washed inside and out with disinfectant and deodorizer. Complete re-assemble of the BCD unit is finished and a 30 minute pressure test for leaks is done.

 Tanks & Valves
Our repair department services many different types of tanks and cylinders. We inspect everything from steel and aluminum Scuba tanks, medical oxygen cylinders, fiberglass reinforced fire fighting SCBA tanks and specialty aviation and marine safety cylinders. There are many tests and inspections done on these cylinders. We have listed some of them below with a short explanation on what is involved.

V.I.P. (visual inspection process) - Done every year
The tank is first emptied, and the valve is removed. A complete assessment of the valve is done checking for correct working order, severe corrosion, broken parts, etc. The two main o-rings are removed and replaced. Next, an external inspection of the tank is done. Here we check for corrosion, pitting, dents, and signs of fire damage. An internal inspection with a fiber optic light and dental mirror is performed. Again checking for corrosion, pitting, water, oil, silicone, or any other contaminates. Finally the valve, with new o-rings, is reinstalled , a new VIP sticker is applied and the tank is filled and checked for leaks.

Visual Plus - Done every year (aluminum cylinders only)
The Visual Plus inspection is done to check for cracks in the neck and threads of a cylinder. It uses eddy currents to inspect the alloy at the top portion of the cylinder and shows any Sustained Load Cracking (SLC) abnormalities. If a cylinder is suspected of having cracks, the cylinder is either shipped back to the manufacturer for further testing or discarded. In most cases, the suspected cylinder is condemned and taken out of service. This test is done on all aluminum cylinders (i.e.. scuba, scba, oxygen, medilux,CO2) and is done in conjunction with the V.I.P. , as described above, every year.

Hydrostatic Testing - Done every 5 yearsDave hydrostatically tests tanks at Divers Market
After the V. I. P. and the Visual Plus inspections, the cylinder is filled with water. The cylinder is then submerged in a vat of water with a secured lid. All the air is purged out of the cylinder being tested and the vat it's submerged in. Next, the cylinder being tested is pressurized, using water pressure, to the D.O.T. specified directives. Normally this is 5/3 the working pressure of the cylinder (i.e. an aluminum 80 normally gets filled to 3000 psi and is hydro-statically tested to 5000 psi). When the cylinder is pressurized, it expands. The amount of expansion is measured through displacement in pipette tubes. When the pressure is released a second measurement is taken for permanent expansion results. If the permanent expansion is within limits the tank passes and kept in service. The tank is emptied of water, dried, stamped with the month, retesters I.D. Number, and year. The valve is installed, and the cylinder is filled and checked for leaks.

"Whipping" and Cleaning
When severe corrosion is found inside tanks it is sometimes possible to clean the corrosion out (depending on the degree of the damage). This is done with one of two ways. One is to "whip" the inside of a steel cylinder with a series of special wire brushes. Then rinsed and dried. The second method is to clean the inside of aluminum cylinders with an industrial cleaner, rinse, and dry.

Exposure Suits

Our Repair Department services all drysuit repairs including replacing neck seals, wrist seals, booties, and zippers. We also install pockets, warm neck collars, zipper guards and many other added options. We pride ourselves on keeping the repairs in-house. Which means quicker turn around times and a higher level of quality assurance.

Here you can take advantage of our two in-house sewing machines and experienced staff to personalize your wetsuit. We offer custom tailoring, added options, repairing holes and tears, and specialty modifications and developments. One of our past challenges was to build a custom wetsuit for a German Shepherd!

Computer Battery Replacements
It is a good idea and a good habit to replace your computer or timer batteries regularly. We freshly stock most manufacture's batteries. The battery is replaced along with the catalyst or moisture capsule in the computer. We have the ability to test the unit for its waterproofs and depth accuracy in our very own underwater compression chamber.
