Water pressure in Multi Story Apartments

 

This week at Octave Design Services, we've been working on water system calculations for a 4-storey apartment block (Ground to Third Floor) using h2x software. 

 

We measured incoming mains pressure at 1.7 bar—on the lower end. We'd usually expect around 2.5-4.5 bar. However, utilities companies will only actually guarantee 1.0 bar; but with no room for a central booster set or break tank, we used software modelling to predict the performance, with and without boosted water. 

 

The results showed that individual booster pumps (e.g., Dutypoint Scubatank or Grundfos Homeboost) are required for 2nd and 3rd floor apartments to maintain acceptable pressure levels. 

 

We then put the information onto a detailed, but clear schematic drawing. 

 

Relying on mains pressure alone often leads to poor shower performance above the first floor—especially problematic for top-floor premium luxury penthouse type units! Homeowners do want an awesome shower when they have splashed the cash. 

 

If you're working on a multi-storey residential project and want to avoid water pressure issues, get in touch. We offer detailed domestic water calculations and CIBSE-compliant designs tailored to your scheme.
