• The higher the pressure in the dispense container, the more carbon dioxide will dissolve in the beer. Common sense; if you want to fit more in there, push harder.

• The higher the pressure in the dispense container, the more carbon dioxide will dissolve in the beer. Common sense; if you want to fit more in there, push harder.
The proper level of carbonation, in addition to its sensory augmentation of a beer, is critical to a good pour. Brewers measure carbonation as volumes of carbon dioxide. If a beer has two volumes of carbon dioxide, this simply means that if all of the carbon dioxide were removed from a beer at 68° F (room temperature) at sea level under normal atmospheric pressure, the space taken up by the carbon dioxide removed would be twice that of the beer.
Ideally, beer lines should be cleaned between each keg, and once every three weeks at the minimum. Over time beer will produce mineral and protein deposits in the draft lines. Bacteria and molds can work their way into the lines, and yeast can form colonies as well. The responsibility for line cleaning is ultimately yours, but the distributors, brewers, and even independent contractors might be involved. Line cleaning can be done with several solutions and contraptions. The equipment is available relatively inexpensively through draft suppliers. [links]
If the engine "pops" or hesitates upon acceleration from a standing stop, it can be caused by an air leak. Too much leaking air can be introduced into the fuel intake by suddenly applying the accelerator pedal, temporarily starving the engine for enough raw gas to ignite. Other ignition components should be ruled out first, like worn plugs, dirty fuel injectors, a cracked coil, etc,. here
With the majority of air leaks around the carburetor and throttle body there will be a detectable hissing noise. It means air has been forced to enter a tight or restricted passage (breach) and a hissing or whistling sound results. Sometimes the hissing noise can be very loud, calling obvious attention to itself.
Provided the idle mixture adjustment screw looks good (clean needle end) and seats into the carburetor, if it refuses to affect the idle speed at all when turned in, it means that air leakage has bypassed it, making it inoperative.
A rough idle, or "loping", which can sound almost like a high performance cam can be a telltale sign that the carburetor or throttle body has allowed a constant flow of air into the intake manifold. Extra air leans the mixture out and fuel can not burn properly when entering the combustion chamber. This causes a constant (lean) misfire. Ruling out an EGR valve that can be stuck or a loose or defective PCV valve, will narrow the problem down to an air leak in the carburetor. A serious leak with massive amounts of air flowing into the system can cause non-idle condition, forcing the use of the gas pedal to keep the vehicle running. Extremely lean mixtures caused by air leaks produce excessive HC (hydrocarbons), and such vehicles almost always fail an emission control test.
Carburetor air leaks, typically known as vacuum leaks, can be one of the most baffling repair problems to solve. Air intake leaks around the carburetor, especially at the throttle body (base), can go undetected because another system usually gets blamed for an engine miss, sporadic rpm behavior, stalling and sometimes overheating. The normal repair person might think that the ignition system (high-energy ignition or plugs) has caused the symptoms. Hiding just out of reach, the illusive vacuum leak can be detected if you know what to look for.
In the normal course of the day, we all swallow some air. This air is generally released through the process of burping or belching. However, this air can also make its way to the large intestine, where it is released through the rectum as flatulence. more
There are things that can cause a person to swallow more air than normal. If any of the following apply to you, you now have something to work on: more
Some substances in the food that we eat are not well digested and absorbed by our bodies. When these substances, mainly carbohydrates like simple sugars and starches, arrive in our large intestines, they are acted upon by bacteria within our guts. The result of this breakdown is the release of gas. This gas is usually carbon dioxide, hydrogen, methane, and nitrogen. Although some of these gasses may be absorbed into the bloodstream and exhaled out, most of them are released through your anus. more

The network of drain and vent lines in your house is called a drain-waste-vent system, a nomenclature that emphasizes the fact that the vents are as important as the drains and waste lines. The purpose of the vent pipe on the roof of every house that has a bathroom isn't just to dissipate sewer gases, but to provide an way for air to get into the plumbing pipes and equalize pressure. Within a specified distance of every drain and toilet is a tee that connects to an upward-sloping pipe that connects to the main vent. more
Emptying a bathtub or flushing a toilet releases a large amount of water which forms an airtight seal in the pipes while it is flowing. As a result, it creates a pressure difference between the air it's pushing in front of it and the vacuum it leaves behind. If the vents aren't working, air has no easy way to get into the pipe to fill the vacuum, and it begins to enter through sink, tub and shower and even toilet P-traps. You usually hear a hissing or gurgling sound from the affected traps, and if the vacuum is strong enough, it can pull all the water out of them. more
Burping and hissing sounds can happen as a result of the air in front of the head of water trying to escape from the pipes. They happen, for example, when a fixture, such as a sink, is connected between a toilet and the main stack, which is the vertical pipe that drops to the sewer. If the sink doesn't have a working vent, air bubbles form behind the water barrier of the sink P-trap, and they eventually force their way through. A large bubble makes a burp while a continuous flow of air makes a hiss. more
Sounds coming from your plumbing pipes, including burping, hissing and gurgling, happen because of the movement of air. The cause is usually a pressure imbalance caused by flowing water, which pushes air in front of it and leaves a vacuum behind. The plumbing vents, which are required by code, are supposed to prevent this, so the sounds mean that something needs to be fixed.
