Booster Pump Pressure Calculator
Boost pressure a building set must add to serve the top floor at proper pressure.
Plumbing codes want 100โ150 kPa at the worst fixture and under ~550 kPa at the lowest (or PRVs). One bar of boost per 3 floors is the quick check.
Formula
Booster Pump Pressure Calculator is a free booster pump for pump engineers, plumbers and plant designers โ instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Booster Pump Pressure Calculator
Boost pressure a building set must add to serve the top floor at proper pressure. The calculation implements Boost = ฯgยทH_floors + P_residual + h_f โ P_supply (IPC/UPC fixture pressure requirements; IS 1172). Plumbing codes want 100โ150 kPa at the worst fixture and under ~550 kPa at the lowest (or PRVs). One bar of boost per 3 floors is the quick check.

Frequently asked questions
What formula does the Booster Pump Pressure Calculator use?+
It computes Boost = ฯgยทH_floors + P_residual + h_f โ P_supply, per IPC/UPC fixture pressure requirements; IS 1172. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Plumbing codes want 100โ150 kPa at the worst fixture and under ~550 kPa at the lowest (or PRVs). One bar of boost per 3 floors is the quick check.
Can I use this for pump selection?+
Use it to establish the duty (flow, head, NPSH, power) and then pick a pump whose curve passes through that point near best efficiency. The tool gives you the engineering numbers a supplier will ask for.
Is the Booster Pump Pressure Calculator free to use?+
Yes โ completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
