On site flow rate testing can be carried out by an appropriate professional to determine the flow rate of taps. This must be overseen by the client’s facilities manager and as-built drawings must be provided to confirm the presence and location of the fitting and any flow restrictors. Note that the conditions under which the testing is completed must be recorded, i.e. the pressure and the temperature of the water. The assessor could conduct the test provided they are able to carry it out accurately.
