Key Differences between Hunter I-20 And PGP Sprinkler
- Radius
Hunter I-20 Sprinkler can spray water 4.9 to 14.0 meters from the middle of the circle side of the circle.
Hence, it has decent coverage to easily water small or mid-sized lawns.
In contrast, Hunter PGP Sprinkler can easily cover 6.4 to 15.8 meters of space.
This makes them a perfect choice for a more extensive lawn. But make sure to maintain sufficient areas between Sprinklers.
- Flow
The flow rate of Hunter I-20 Sprinkler is 0.07 to 3.23 m³/hr. You can effortlessly adjust it. This will ensure a better irrigation system as the water can reach areas quickly.
On the other hand, Hunter PGP Sprinklers come with a flow rate between 0.10 to 3.22 m³/hr. Though it is slightly slower than the other option, it combines better for its higher coverage.
- Inlet Size
Both sprinklers require a ¾” BSP inlet. You will connect it to the water supply to ensure a free water flow to the sprinkler valve.
Make sure to measure to install it correctly. You can use a piece of string for an appropriate measurement. For smooth water flow, your sprinkler pipe needs to be more extensive than the sprinkler inlet.
- Operating Pressure Range
Both units allow a pressure range of 20 to 101 psi. These two sprinklers are excellent for achieving low, middle, and higher water pressure. This makes them highly versatile.
But avoid using more than 80 psi unless your household appliances have the capabilities to endure. Usually, you can spray easily by maintaining the psi between 40 to 80.
- Specialty Nozzles
Nozzles play a crucial role in changing the direction and speed of the water flow, which is located at the upper area of the sprinkler head.
Hunter I-20 Sprinklers come with preinstalled nozzles. You don’t need to install them separately. In contrast, Hunter PGP Sprinklers don’t have any nozzles. Separately buying them is necessary.
- Nozzle Choices
You need 34-rated nozzles for Hunter I-20 Sprinklers. In contrast, Hunter PGP Sprinklers require 27-rated nozzles.
It is better to install larger nozzles if you want to work with lower water pressures. This will prevent the reduction of sprinkler time per rotation and unbalanced water distribution.
- Applications
Depending on size and features, it is crucial to use a sprinkler system at the appropriate place.
You can use Hunter I-20 Sprinklers in Residential, commercial, athletic fields, reclaimed water, and high vandalism areas.
On the contrary, Hunter PGP Sprinklers are a better choice for Residential and low-pressure areas.
This comes in handy for household areas, where there is a strict rule on water pressure standards.
- Warranty
Hunter I-20 Sprinklers have five years of warranty. This makes the product more reliable. Hence, you can keep yourself worry-free for a long time.
On the other hand, Hunter PGP Sprinklers offer only two years of warranty. Though they are not as convenient as the other option, you will not see failure issues too soon.
- Price
Hunter I-20 Sprinkler is the latest product that has many advanced features. It features FloStop control and efficient nozzles to make the spraying session smooth and hassle-free.
On the other hand, Hunter PGP Sprinklers have an affordable price. This makes it a perfect choice for households where you don’t need extremely powerful units.
Which Sprinkler Is The Best For You?
Choosing a quality sprinkler requires first considering your location and water pressure level. Hunter PGP Sprinkler appears a great choice if you want to use sprinklers for household purposes.
It can cover larger-sized lawns without compromising the water flow significantly.
On the contrary, Hunter PGP Sprinklers are perfect for commercial and high vandalism areas, where you can utilize higher water pressure. But avoid using more than 80 psi unless you don’t need it.
This may cause gradual damage from continuous practices. Here is a little more about it.
