A well pump professional typically uses a pump puller machine or a derrick truck to remove the old well piping. A well pump installer provides an installation video for a replacement 3/4 HP submersible pump, while a well owner demonstrates a shallow jet pump used for landscape irrigation. The water system should be disinfected and re-tested after any work is done.
The air that people breathe is a mixture that contains primarily oxygen and nitrogen. The nitrogen generally makes up approximately 78%, while oxygen makes up 21%. Other gases, including carbon dioxide, hydrogen, helium, argon, and neon, make up the remainder. These gases dissolve and are carried in the blood.
Due to some heart and lung conditions, not enough oxygen is able to get into your blood to supply your body. Once your condition has been stabilized by medications, supplemental oxygen is used to correct a low oxygen level. This is a common misconception that many people using oxygen have heard. The air we breathe is 21% oxygen. Most people using oxygen are only receiving a slightly higher percentage (about 28% at 2 lpm). This is just enough to bring your blood oxygen levels back to an adequate level.
