Measuring flow rate
With the shower handset connected, using a measuring jug, collect 1 litre of water and
time how long this takes.
60 Divided by the time taken = Flow Rate LPM
e.g. 60 Divided by 20 seconds = 3 LPM
Frequency of in-service tests
General
Following the commissioning of the shower, or any significant repair, the installation should be re-tested
within a 6-8 week period.
If no significant changes (eg less than 1
°C) in outlet water temperatures are recorded between tests,
then the next in-service test can be deferred to 24-28 weeks.
If there is a significant change then contact Technical Help Desk- see back page.
