When you decide to go with sprinkler irrigation techniques, you come across two options: Metal and Plastic sprinklers.
Both offer different types of sprinklers according to your need, but choosing the correct sprinkler for your irrigation technique is tough.
So here I made a post explaining the Metal and Plastic sprinkler pros and cons with the exact differences that will help you make an informed decision.
Metal Sprinkler
Metal Sprinkler is made of Metal, most commonly Brass.
Metal sprinklers come in different types to suit your irrigation needs.
You can use these sprinklers for a long time and handle them roughly.
Here are some Advantages of Metal Sprinkler that provide you with better insight:
- Durability: You can use Metal Sprinklers for a long time, even more than 10 plus years.
- Sturdiness: They can withstand rough usage, such as if your dog bites them in the garden.
- Repairability: Even if there is a problem with a Metal Sprinkler, you can repair it with proper spares like nozzles and washers.
Ok, now let’s consider some Disadvantages of Metal Sprinkler.
- Higher cost: Metal sprinklers cost you more than plastic because it is made of metal.
- Corrosion: Corrosion is due to the poor quality of water. So you’ll have to frequently check the nozzle threads if threaded or tightened on sprinklers need tools to change the nozzle or even remove debris stuck in its aperture.
- Water pressure sensitivity: As water levels decline, the operating pressure of sprinklers decreases, affecting the uniformity and droplet size of brass sprinklers.
Plastic Sprinkler
Even though sprinkler irrigation started with metal sprinklers and pipes, the usage of plastic sprinklers has increased more than that of metal ones.
Plastic sprinklers are cost-effective, easier to handle, and available in a variety of types that can fit your specific needs.
Here are some Advantages of Plastic Sprinklers.
- Low Cost: Cost-effective and cheaper than the metal one.
- Low Maintenance: Easier to handle and require less maintenance.
- Good Water Distribution: Plastic sprinkler nozzles are made of non-abrasive materials; nozzle sizes do not deteriorate over time, and sprinkler uniformity is maintained for many years.
Some Disadvantages of Plastic Sprinklers.
- Not for Rough Usage: You cannot use plastic sprinklers for rough usage in extreme hot and cold climatic conditions.
- Plastic sprinklers may not be suitable for long-term usage.
Difference Between Metal and Plastic Sprinkler
| Metal | Plastic |
| Metal sprinklers are best suited for long-term usage as they are durable and can withstand harsh weather conditions. They can be repaired if they are broken or not working properly. | Even though plastic sprinklers are made out of plastic, they are not sustainable for extremely hot and cold climates. |
| The cost of sprinklers has increased due to the growing use of metals, particularly brass/gunmetal. | Plastic sprinklers are 60-50% cheaper than Metal sprinklers. |
| Even though water may appear clean to the naked eye, it often contains sand particles, particularly in borewell water, which can cause abrasion. Over time of 1 to 2 years, this abrasion can lead to nozzle enlargement, resulting in uneven and poor water distribution. | Plastic sprinkler nozzles are made of non-abrasive materials; nozzle sizes do not deteriorate over time, and sprinkler uniformity is maintained for many years. |
| Metal sprinklers not only provide efficient functionality but also add an aesthetic look to your garden or farm. However, they require regular cleaning to maintain their appearance over a long period. | Plastic sprinklers look astonishing for a few days, months, or even years, depending upon usage, but over time, the color fades away. |
| Fertigation is not possible as it leads to corrosion of metallic sprinklers. | Fertigation is possible with plastic sprinklers as there is no corrosion since they are made of plastic. |
| It can sometimes be challenging to fit metal sprinklers into your existing irrigation system due to differences in threads or sizes. | Plastic sprinklers cost less than metal ones, so it is easier to replace them if they are not fit for the current irrigation system. |
Final Thoughts…
Both metal and plastic sprinklers offer their own set of advantages and disadvantages. It is ultimately up to you to determine which sprinkler is most suitable for your specific needs.
If you require a sprinkler that can withstand harsh environmental conditions and has a longer lifespan, then a metal sprinkler is recommended. On the other hand, if your irrigation needs are temporary and you prefer a more cost-effective option that requires less maintenance, a plastic sprinkler may be the better choice.
Consider your specific requirements and budget to make an informed decision on which type of sprinkler will best meet your needs.
