14.5 Pressure drop
14.5.1 Taps/valves
Pressure drop at flow rate 10 l/min
Mono-lever mixer tap, approx. MPa 0.04 - 0.08
Thermostatic valve, approx. MPa 0.03 - 0.05
Hand shower, approx. MPa 0.03 - 0.15
14.5.2 Sizing the pipework
When calculating the size of the pipework, a pressure drop for the
appliance of 0.1 MPa is recommended.
14.6 Fault conditions
In case of faults, loads up to a maximum of 95 °C at a pressure of
1.2 MPa can occur temporarily in the installation.
