1 bar is enought to lift water 10 meters up. The pressure gauges reads zero at atmospheric pressure.
Comment on Does different parts of the world use different standards for water pressure similar to voltages?
Agility0971@lemmy.world 5 months agoWill any pressure below 1 bar work at all? Wont it just suck the air in instead?

Ahh, relative pressure

The gravity systems are in this case not pressurized. They just have a water tank in the loft/airing cupboard and the hight of the tank determines the pressure. 0.1 bar for every 1 meter height. You open the faucet and gravity pushes out the water.
Its a nightmare, I used to live in UK and these systems are barely enough for anything really.

These pressures are all gauge pressure, not absolute pressure. 1 bar gauge pressure would be about 2 bar absolute.
