Comment: I've got really good pressure. |
|
| |
| Each sprinkler uses a set amount of water,
therefore, we would still like to know how much water
comes out of your tap so that we can tell you how many
sprinklers to run. Additionally, you can still have the
appearance of good pressure from your tap due to water
velocity, while at the same time, the smaller supply pipe
sprinkler pipe is actually reducing your available flowrate.

2. What sprinklers do I need? |
|
| |
| Sprinklers do throw different distances,
so once you know the length & width dimensions of
your area it becomes easier to choose the correct sprinkler.
If you draw your yard to scale (1:100 is good) it will
become quite evident as to how different in size the actual
areas are around your home. |

| 3.
What size pipe do I use? |
|
| |
Pipe size selection
depends on three things
- What your available flowrate is.
- How many sprinklers you are running.
- Are you laying your pipe over a long
enough distance that will be using up too much pressure.

How many sprinklers can I run? |
|
| |
| This comes down
to how much water each individual sprinkler uses, compared
to your available flowrate and pipe size. |
|
| 5.
How long do I run my sprinklers for? |
|
| |
| As a general guide use 30mm of water per week
as an average precipitation rate for your lawn & garden
areas, and apply + or - to this figure for the more or
less thirsty areas of your yard. You can determine your
sprinkler zone's precipitation rate by placing a container
within the area to catch the water from your sprinklers,
then compare the depth of the water to the time it took
to collect (e.g. it took 30 minutes to collect 10mm of
water). |

6. What should I do so that I don't waste
my money? |
|
| |
| Ensure Head to Head sprinkler layout,
and do not exceed your pipe flowrate capabilities or 80%
of your available flowrate. |
