It does not increase the pressure it remains the same as if the valve was open.
Water chemically reacts with the cement to form a new compound. The resulting concrete gradually reaches full strength over 28 days, but most of the strength comes in the first 3 days, so that is when most of the water is used and needed.
yes, because after casting, concrete will get its 90% strength within 28 days and proper hydration require the proper amount of water for atleast 28 days.
Well if you just carry on as normal and let the water run eventually all the air should come out. That's what i did and it work. It took about 2 days but i didn't have much air in my pipes. It can be difficult. Most homes in the US are required to have a device that prevents air hammers, which risk shaking pipes loose and cause flooding. One thing that may help is to turn off all the water in the house and opening the very top valve in the highest place in the home.
depends on the thickness and the water content, 3-4 days is safe for all
Iron rusts easily when combined with water, and drain pipes have water flowing through them. If iron was used, the pipes would rust within a few days.

Around 3 days depending on water pressure.
No, the original toilet was made to be sat on the same way we do these days.
My husband always says he feels pressure and pain in his testicles if he doesn't have an ejaculation every few days. But I guess if priests can go their whole lives without release, then it's not as important as using the toilet.
Well you can't really have to much water but it's good to have at least 2 or 4 a days When your stomach aches with exhaustion and you can't stop shaking and going to the toilet for a wee.
Sperm pressure can be increased by doing pc mucle contractions, drinking lots of water and cumming every 3 days
On the toilet?
About 10 days.
About a week.
allow the unit to operate until the flame goes out
Pounds per Square Inch is a measurement of pressure, be it water, gas, or air from a pipe or put into a storage tank, etc. A basic example is that a pressure gauge on a water boiler may be set to 80psi, and a safety valve will open to allow excess pressure over the 80psi to escape.
