Water Pressure above 4th floor.

[MasterPlumbersKeymaster]

hello,
i’m living in 6 floors apartment building.
we have poor water pressure, espcialy over 4th floor.

we checked the water pressure near the main water meter at the ground floor, it was 2.5 -2.7 atm.
we have a dispute with the city water dept.

i claimed that at the ground floor it should be at least around 4 atm. what is the water pressure that is in australia for such buildings.
thank u.

Zisi. In Queensland Australia, & I believe the rest as well we must have 5m head or fifty kilopascals thats about 5-6lb at any tap outlet with all taps on. We must pipe size the system to atain that output.

Same HERE at the uper most floors 6-8 PSI at the “faucet ” tap but many flushometers will not work under 35 PSI

The Code I normally use says the city is responsible to get water to the basement.

Reason being the water system here is gravity fed and many buildings are well over 47 stories heigh so the city will not be responsible for getting water this height.

But lucky we have foreign trained mechanics Like Canada to install the proper sized pumps and piping systems.
