In the US for example the standard is 110V for voltage and 80psi for water. In Europe, voltage is 220V, is water pressure different there too?
Water operates more like DC voltage so there isn’t really a need for a standard. You just need enough to get to your shower head.
That’s an interesting analogy. But just like too much current can melt a wire, I would assume there’s some upper limits to keep it from bursting pipes and fittings?
My house is operating at around 3,5-4 bar after the pressure regulator. Since I have no gauge I can‘t deliver the pressure of the supply. I guess it is around 6 bar. Small town in Germany.
We also have mandatory check valves since a couple of years to prevent water from entering the supply from the buildings in case the pressure drops.
The most common one is bar. 1 bar is roughly the atmospheric pressure.
An older German unit was atü, 0 atü is atmosperic pressure
Edit: sorry I misunderstood the question
Noggie here. Code dictates a minimum of 2Bar (~30psi), but it’s usually between 3-6 bar.
The pressure at my house was recently measured as I had some plumbing work done, and in my 2nd floor bathroom it clocked in at around 5 bar (75ish psi, I think)
It’s 120V and 240V
Is that substantial though or is it like calling 120V something like 110V/115V?
Hes just being pedantic. Reality is US houses get a +120v and a -120v supply. Combine them is how you get 240v.
sorry dude thats not right. first off houses recieve AC power which cycles between positive and negative at 60hz ~120v rms in north america. they achieve a potential difference in voltage by basically taking a phase of power, splitting it into two lines and then lagging one line by 90° usually with the use of capacitance from what i was taught back in the day(Good ol ELI the ICEman). this phase shift now gives you a potential difference between those two lines of 240v and 120v between phase and ground. need to use phasor algebra with AC power. when dealing with 3 phase power you still wouldnt just add 120v plus 120v when going phase to phase, you would multiply 120v by the square root of 3 which gives you 208v.
