There is always a risk of flooding with any water supply, however, because of the high pressure of this supply a leak may spray water over a very large area. This water spray can reach electrical equipment and give a high risk of electric shock.
All valves, fittings and hoses used on the high pressure water system must be able to withstand pressures well in excess of 100 psi. Hose connections should be rifled and the hoses securely clamped.
