Note the time to fill a standard 9
litre household bucket, from the
tap to be used for your watering
with the tap turned on full.
Each Pop-Up details its Pope Rating Points PRP’s™, refer
to “Performance Specifications” chart on page 13. The
Pop-Up PRP’s™ must be added together to ensure they
do not exceed the total PRP’s™ available from your tap.
In our example, 43 PRP’s™ were available.
The total number of Pop-Ups you can use at one time is limited by the water flow from your
tap. Read off the number of Pope Rating Points PRP’s™ you have available from your tap.
For example if it takes 10 seconds to fill your 9-litre bucket, move along the bottom line
of the chart
A
to the 10 second point. Move up the blue vertical line from the 10 second
point to the dotted line and across the horizontal red line to the PRP’s™
B
. This shows that
this tap has 43 Pope Rating Points PRP’s
™
available for use.
