A scuba tank is design to hold a certain volume of air, at a particular at a particular temperature. In the US, the standard tank is an aluminum 80 CF tank. At room temperature and 3,000 psi, the tank holds 72 CF of air (yeah, I know they round up calling it 80 CF tank). When you are filling the tank, the air and tank will become warm/hot. If you check the pressure guage while the tank is warm, it will give you a reading of X. Once the tank cools, it will give you a reading that is less than X. They put the tanks in the water in the hopes of keeping the temperature do, and filling the tanks closer to the design pressure and temperature. Some examples that you can see... In Mexico, many of the tanks will be sitting in the sun while on the boat. The tank may have a reading of 3,200 psi. Once you jump in the water, and the tank cools down, the new reading may be 2,800 psi without ever breathing any of the air. I have been ice diving, the tank was acutally colder than the water. Since the water temperature was warmer than the tank, me pressure reading was slightly higher.

Any preesurised gas container should be visually inspected annually (at least) and pressure tested every 5 years, 3 years or annually according to local law. If you are going to have it tested, screw the valve in loosely as they will need to examine the threads on it in order to pass the tank and valve as a unit. BUT ALL THAT ASIDE, the answer to your original question is: Replace the tank neck O-ring, very lightly lube the threads of the valve with a SCUBA silicon grease, wind the valve in to finger tight (if you have a torque wrench you could find out setting) if no torque wrench, nip the valve tight with a light tap from a rubber mallet on a 12" wrench (I know it is a bit approximate, but the O-ring makes the seal, not the tightness)

There are four main variables affecting this: 1. The (total) internal volume of the tank(s) 2. The pressure to which that tank has been filled 3. The ambient pressure at depth 4. The rate at which the diver uses the air out of that tank for their breathing and buoyancy control (including drysuit inflation). The first three are simply a matter of physics and will be the same for everyone under the same circumstances. The major variation comes from the last one, which is usually a function of the diver's experience/ competence (not the same thing!). One who is less so will go through air quicker than one who is more so. So the best answer for your question is "It depends..."! However, many resorts and guides set a maximum dive time of one hour, so they know when to expect a diver back on the boat (or, when they have to call out the Coastguard!). This might be the source of your friend's assertion. FYI: The current world record for breathing off a single tank of air while sitting at the bottom of a swimming pool is a little bit short of 8 hours. The divers in question were using 12-litre cylinders charged to 200B and breathing verrrry slowly! (approximately 12 x 200 litres / 460 minutes = 5.22 l/min)

"There is only one bit of advice you need when you own your own tanks: bring them to a professional for filling and regular inspection. Tanks are required to be visually inspected once a year, which involves removing the valve and looking inside for signs of corrosion or damage. If the tank is deemed safe, an Evidence of Inspection (EOI) sticker is applied to the tank showing the date of inspection. A hydrostatic test is required every 5 years, which determines the tank's ability to contain pressurized gas. A certified hydro test facility will stamp the shoulder of the tank below the valve with the date of pass. This inspection makes it easy for you to know if your rented tank has been properly maintained and inspected. If the hydro test stamp is more than 5 years old or the EOI sticker is more than a year old, don't accept the tank. Corrosion is the major culprit in tank degradation. Scuba tanks are filled with very dry air, to prevent moisture from rusting the interior of the tank. That is why certified divers learn never to leave a tank empty. Always leave at least 100psi of pressure in the tank at the end of your dive, so no moisture can get in when valves are opened."

"The scuba tank is one of the most important pieces of dive equipment. It must be looked after. A well-maintained tank could give 20 or 30 years service. A neglected tank can fail with the force of a hand grenade. It pays to care for a scuba tank, not only for economy, but also for safety and diving enjoyment. The following ten tips can help ensure a scuba diving tank will provide many years of faithful diving service. 1) Never completely empty a scuba tank. Always leave at least 1000 kPa to ensure moisture doesn’t enter. 2) Always rinse the scuba tank and valve in fresh water after use. 3) If the scuba tank is to be stored for a few months, drain the air down to around 1000 kPa. This is to decrease the amount of oxygen that can cause corrosion. 4) A scuba tank should be stored standing up out of direct sunlight. 5) A scuba tank should be carried with care and attention. They shouldn’t be carried on the shoulder as a fall can lead to the valve getting smashed off and the tank taking off like a rocket. 6) A scuba tank should be regularly tested in accordance with statutory regulations. 7) A scuba tank should not be left in a closed car in the heat of the day. It can heat up and explode or the burst disk can rupture; both scenarios leading to damage to the car. When in the car the tank should be carried with the valve towards the back. If the car brakes suddenly the tank valve won’t be damaged as the tank moves forward with its momentum. 8) The scuba tank valve should not be turned off too tightly. It only has to be just nipped closed enough to stop the air flow. 9) A scuba tank should be filled with clean, dry air. Any discolouration around the air outlet or bad odour should be treated with suspicion. If there are any doubts that a tank has been filled with bad air, it should not be used for scuba diving and should be checked immediately. A bad fill can lead to damage to the tank, as well as pose a threat to a diver. 10) If painting a tank, ensure no heat curing paints or strippers are used as these could affect the strength of the tank."

the law of buoyancy is the principle that describes why some objects float over water and some others sink: when you put something in water, it receives an upword force equal to the weight of the water it displaces.
this is important in diving in many ways.. and in particular, in diving, you always want to have a neutral buoyancy: this means that if you are standing still in water and you have a neutral buyoancy, you don't sink nor come back to surface

you have a neutral buoyancy if you "displace" always the correct volume of water.. in other words, you always need to occupy about the same volume: if you go in deep water, the water pressure will "reduce" your volume, so to mantain a neutral buoyancy you have to inflate air in your buoyancy compensator jacket to expand its volume.
otherway, if you're coming back to surface, pressure reduces and your body occupies more volume, so you have to deflate your jacket.

it depends on the quality of the mask and it depends on how you stored it (if you leaved it at sunlight, if you washed it thoroughly after using it in the sea...)
i have a mid quality mask Mares mask, i have been using about 20 times for snorkeling, then i used it to take diving certifications in pool, then i used it for about other 20 dives in the sea... i always stored it in a dark bag (the mask is now about 8 years old)
you can check if you mask is still in good shape, and the silicone has not worn out, in this simple way: just put the mask on your face without straps.. remove all the air inside the mask by inhaling with your nose.. then look at your feet (keep inhaling): if the mask remains on your face you can keep using it

The two main types of dive computers are wrist dive computers and console dive computers. Wrist dive computers are actually just like wrist-watches (a little bigger) and are worn on the diver's wrist. Right now, they are smallest dive computers available.

Console dive computers are attached to the diver's equipment by a hose. Main difference between console dive and wrist dive computers is that console dive computers include pressure devices in them.

You need to consult with a factory technician. Your life depends on these devices. I am certified in USD Survivair and no one can set those after a rebuild kit without special tools and measuring devices.

I would say no. The water in the pipe that is above sea level will drop back in the pipe until it reaches sea level. Provided neither end of the pipe whether above or below the sea is blocked the level in the pipe will always find natural sea level so it wont be higher or lower than sea level. So in answer to your question No it wont pour out.
