Hookah Regulators


Hookah rigs deliver air from a compressor on the surface down to a diver below, just like those old school cartoons. Divers doing serious long term jobs underwater may opt for these regulators, which are specially designed for hookah style diving. Please bear in mind that a regular scuba diving regulator cannot be used for hookah applications! Hookah regulators function with a different set of pressures and have specific regulators for specific conditions.

A Hookah regulator setup is entirely different from a scuba regulator. It consists of a 'second stage' only, which is fed directly from the output of the reserve tank via a Hookah air hose. There are no tank valve and first stage regulator assemblies of the type that are used with scuba cylinders.

Hookah second stage regulators typically employ a 'tilt', or 'pin' valve, which delivers a full airflow to the diver at low-pressure. This type of regulator is specifically designed for use with low-pressure Hookah compressors. Hookah second stage regulators, as are all modern regulators, are of the single hose, 'demand' type. A 'demand' regulator works on a relatively low volume of air since it only has to deliver air as the diver breathes, or 'demands' it.

Scuba second stage regulators typically can't be used for Hookah applications without special modifications. A typical Hookah compressor operates in a low-pressure range which is not enough pressure to drive the spring-loaded downstream valve of a scuba second stage regulator.

A diver who already owns a scuba second stage regulator, but who wishes to use it for Hookah applications, must take the regulator to a competent dive shop and get the regulator converted over for low-pressure use. The conversion can be made by installing a set of low tension springs which will give maximum efficiency when operated at low Hookah pressures. A dive shop will also have the necessary test equipment to make certain the adaptation has been effective.

Please read Introduction to Hookah Diving for more information about things you need to consider with a hookah diving setup.

Kakariki Wreck

The Kakariki shipwreck, lies near Gellibrand Pile Light, Williamstown, Port Phillip. On 29 January 1937, the steel steamer collided with another steamer Caradale off Williamstown, sinking within minutes and killing five people. Police divers recovered the bodies of three of the five missing members of the crew.

Salvage was hampered by the vessel being stuck in four metres of mud. The wreck was eventually blown up, but parts of the mast, bridge and bow still remain.

There seems to be more of the Kakariki wreck nearby at:

Kakariki Shipwreck History — Built in 1926

The Kakariki was built in 1926 by Cochrane & Son Ltd, in Selby, England. The Units: unknown unit type given interstate trader had an overall length of approximately 190.2 ft (58 m), beam 31.4 ft (9.57 m) and draught 12.9 ft (3.93 m).

Kakariki Sinking — 29 January 1937

The Kakariki was sunk on 29 January 1937 as it headed for Yarraville near the end of a voyage from Strahan, Tasmania to Melbourne with a cargo of timber and ore. It collided with the Caradale, which was bound for Sydney. The Kakariki was struck between forecastle and mess room on the starboard side, leaving a hole 28 feet wide.

Five drowned as the vessel sank within three minutes. The Court of Marine Inquiry laid blame with Kakariki, but a later High Court judgment (26 July 1937) found against the Caradale.

The salvage operations were drawn out over several years, as the Board of Works put the job out to tender and repeatedly took the lowest bid, regardless of the applicant's experience. Several salvage companies lost large amounts of money attempting to move the vessel, and one company lost two staff members during salvage operations.

The Kakariki was eventually moved, in pieces, from the fairway in 1945, and sunk in deeper water.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
