What is noted as the most popular arrangement for contemporary UK (multi-storey) commercial buildings? A Drawing water direct from mains without the interference of booster pumps B High-level booster pumps drawing water from a low-level break cistern and then pumping water direct to outlets C Low-level booster pumps drawing water direct from the mains and then pumping water direct to outlets D Low-level booster pumps drawing water direct from the mains supplying high-level cisterns, and gravity supply of water to outlets E Low-level booster pumps drawing water from a low-level break cistern and then pumping water direct to outlets 4. What potential outlet pressures are noted in the article as being typical of the multi-pump sets that are illustrated in Figure 4?
