Recent Project : Planters' Haven

The area of coverage for this lot of bungalow land is massive. Both drip and pop up sprinklers were installed.

The system were installed during the dry season in February 2014. Note the green grass around the house compound due to the Sprinkler System installation after merely 2 weeks.

Recent Project : Titiwangsa

Another project in KL area. It is a nice bungalow house near Tasik Titiwangsa. 

The project is quite interesting because the owner has Rain Water Harvesting System. Basically, all the water from the roof is channel to a underground concrete tank (about 1500 gallons water). Grundfos pump and water filter were used for the system.

Both drip and sprinkler system were installed. Both Rainbird Rotor and Hunter Spray were used.

Drip System 

Recent Project : Sri Kembangan

We will share some of the recent project executed by Sprinklerhouz. The first of the series is from Sri Kembangan.

The client requested for automatic irrigation system for the whole bungalow. Both drip and underground pop up sprinkler system were recommended to fulfill the requirements.

Both Rainbird and Hunter Sprinklers were used accordingly based on the area of coverage. Rainbird 5000 Rotor were used for 25-30ft radius while Hunter Pro Spray were used for 8-12ft radius.

A total of six water timers from two water source were used for the whole system. Water supply direct from Syabas. No pump and water tank were used. 

Water pressure is about 25-30 psi. This enabled combination of two rotors or four spray to be used for each water timers.

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.

 o

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.

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