15.5 Pressure drop

Pressure drop at taps at flow rate of 10 l/min
Mono-lever mixer tap. approx.
Thermostatic valve. approx.
Hand shower. approx.
Sizing the pipework
When calculating the size of the pipework. a pressure drop for the
appliance of 0.1 MPa is recommended.

15.6 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.
