Most bleaches contain oxygen; drinking water contains oxygen and hydrogen.
However, the element probably meant is chlorine, which is in the most common kind of household bleach (so is oxygen) and in polyvinylchloride, the material that makes PVC pipes. It's not really "used in" drinking water, though small quantities of chlorine compounds may be added to drinking water to "purify" it (really to sterilize it; chlorine is pretty toxic to microorganisms).
Chlorine can be found in both bleach and drinking water.
Yes, the same pipes that supply drinking water to your sink also supply water to your bathtub, toilet, washing machine, exterior spigots, etc.
No, it does not. Drinking bleach is incredibly stupid and dangerous.
I can't think you are talking drinking water pipes because anitfreeze is poisonous. Nor should you have lead pipes or lead solder in drinking water pipes. So either sleeve pipes or heating pipes then. Antifreeze has inhibitors designed to prevent corrosion.
PVC pipes do not corrode, hence these are used for drinking water supply.
Household bleach has about 6 % bleach and 94% is water.Tap water usually has approx. two parts bleach to every one million parts water, or ( .0002 % )bleach and 99.9998 % is water )
To prevent using as potable water.
It can be... especially if it travels through lead pipes.

to keep lead out of drinking water pipes.
people bleach their bathtubs to clean them, so that they can store emergency drinking water
Bleach is NOT meant to be drunk by anyone. It is a poison and will make you sick.
