Pop Up Sprinkler Placement / Pattern Design

We have received many questions especially from our DIY customers regarding the placement of underground pop up sprinklers. Thus, i will explain some important points to be considered when designing Pop Up Sprinkler layout for your lawn area.

As you may know from previous posts, Pop Up Sprinklers come with many different designs and pop up heights. For Rotor type, usually the nozzle will have uniform water distribution inside the spray radius. However, for Spray type, there will be some dry spot about 1-2 ft around the pop up sprinkler. Thus, this is where the term "Head to Head" become important.

Head to Head design means one sprinkler will cover the neighboring sprinkler radius area, avoiding any possibility of dry spot (see the plan below).  This is particularly important for Spray Head type.
As you can see, all of the nozzle overlap (Head to Head) with their neighboring sprinkler.
For step by step design, you many follow the steps below:

Try to place all the underground pop up sprinklers along the perimeter instead of in the middle of the lawn. This will avoid accidental damage by lawn mower. 

For PVC pipe placement,  try to use more parallel design instead of Series to avoid nonuniform pressure distribution. For Malaysia tap water, the pressure usually ranges between 20-30 psi. This is ideal for 4 Spray  Head Type or 2 Rotor Type Pop Up Sprinkler.

Note : The drawings are extracted from Hunter Residential Sprinkler System Design Handbook.

SprinklerHouz Malaysia utilize Hunter, Rainbird, K-Rain and some other USA brand irrigation system for ultimate customer satisfaction.
