Applications
When a fire is declared, the most commonly used extinguishing agent is water, because it is the most abundant, cheapest, and easiest to handle. Normally, water sources do not have the flow and pressure necessary for the proper functioning of extinguishing systems, making it essential to install a fire pressure system to maintain the pressure and flow required by the installation.

Regulations
CEPREVEN-R.T.2-ABA-H2O-1999. UNE 23500 – 1990. UNE 23500 – 2012. These technical rules have been implemented for many years in fire safety, being accredited documents of special utility for techniques related to project and control both in the security sector and in the insurance sector. These rules establish the minimum requirements for these fire protection installations to contribute to achieving adequate quality and efficiency guarantees.
Operation of the Equipment
The entire installation must be pressurized to the design pressure. When this pressure drops by 1 bar, the jockey pump starts and stops when it reaches the nominal pressure. When the jockey cannot handle the demanded flow, and the pressure drops 1-8 bars below the nominal, the main electric pump starts, and the jockey stops. If the main electric pump fails or does not start, the pressure will continue to drop, and when it drops 2-4 bars below the nominal pressure, the diesel pump will start. The only way to stop the main pumps (electric and diesel) is manually.
