The First ChilliChump Video!
Below is a video showing a basic gravity-fed drip irrigation system, it’s actually the video that started everything off on my YouTube channel.
This article is dedicated to helping you understand gravity fed drip irrigation – a cost-effective and water-conserving choice for gardens of all sizes. Let’s dive into this green-thumb game changer!
Height of Water Source And Water Pressure
The height of the water source plays a crucial role in determining the water pressure in a gravity-fed drip irrigation system. As the height increases, so does the water pressure, allowing for better distribution of water to plants.
The most important thing with a gravity fed irrigation system is the height of your water source. The higher you can get it, the better. You will get more pressure, and you will have a more consistent dripper experience. If you only have a few drippers, then you can get away with a lower height.
For every foot increase in height, there can be an increase of about half a pound per square inch (psi) in pressure. So, if you raise your water source high enough, it can have enough push to move through your drip irrigation system easily!
Water pressure from the taps in your house is generally between 20 and 30 PSI (1.4 – 2 Bar). Unfortunately, if you want to get 20 PSI from a gravity-fed drip irrigation system, you will need to raise your water source to 14m (46ft)! At the height that I had my water source in the video at the bottom of this page, I would only have got around 1.5 to 2.5 PSI.
Components of a Gravity-Fed Drip Irrigation System
The components of a gravity-fed drip irrigation system include a water reservoir, tubes and connectors, and mechanisms for controlling water flow.
Water reservoir
A water reservoir is a vital part of a gravity-fed drip irrigation system. It stores the water that will flow to the plants. You can use many things as a reservoir, like rain barrels or large tanks. You could use a rain collection system to keep the reservoirs topped up.
We put our reservoir in a high place so the water flows down using gravity. Keeping it full is important to make sure there’s always enough water for your garden. Don’t let it dry out! The bigger the tank, the less often we need to refill it.
A lid keeps dirt and bugs out of our clean watering system.
Tubes and connectors
In a gravity-fed drip irrigation system, the irrigation tubing and connectors play an important role in delivering water to your plants. These components are designed to connect the water reservoir to the drip emitters or drippers that deliver water directly to the plant roots.
The tubing is typically made of durable materials like PVC or polyethylene and comes in different sizes depending on your needs. Connectors, such as barbed fittings or compression fittings, are used to attach the tubing together securely.
It’s crucial to choose high-quality tubes and connectors compatible with each other. By ensuring proper connections, you can ensure efficient water distribution throughout your garden or landscape.
Pressure Compensating Drippers
Pressure compensating drippers are our preference when it comes to drippers. However, they will not be useful when using a gravity-fed drip irrigation system. This is because these types of drippers expect a much higher pressure. The good news is the drippers that will work are a lot cheaper, they just aren’t as consistent. You can alternatively use drip lines or drip tape.
Benefits of Gravity-Fed Drip Irrigation
Gravity-fed drip irrigation offers several benefits for your homestead. It is cost-effective and efficient, conserves water, and provides targeted watering to plants.
Cost-effective and efficient
A gravity-fed drip irrigation system is not only cost-effective but also highly efficient. By using gravity to distribute water, you eliminate the need for expensive pumps or electricity.
This makes it an affordable option for both small and large gardens. Additionally, since the water flows directly to the roots of plants through drip emitters or soaker hoses, there is minimal water wastage due to evaporation or runoff.
This targeted watering helps conserve water while ensuring that your plants receive the right amount of moisture they need to thrive.
If you are harvesting your rainfall, then not only are you saving money but your plants will prefer the rain water.
Conserves water
Using a gravity fed system helps to conserve water. This is because the system delivers water directly to the roots of plants, minimizing evaporation and runoff. By providing targeted watering, only the areas that need moisture receive it, reducing waste and is a much more effective way to provide water to the plants.
Additionally, gravity-fed systems work at low pressure, which means less water is used compared to other irrigation methods. This makes it an eco-friendly choice for gardeners who want to conserve water and promote sustainable gardening practices, and reduce their reliance on municipal water supplies.
Provides targeted watering with a drip system
Gravity-fed drip irrigation systems provide targeted watering for your plants. With the use of drippers or emitters, water is delivered directly to the root zone of each plant. This ensures that water is not wasted on areas where it’s not needed, such as in between rows or on walkways.
By delivering water only where it’s needed, gravity-fed drip irrigation systems help conserve water and promote healthy plant growth. This targeted watering also reduces weed growth since weeds are less likely to receive adequate moisture.
Overall, using a gravity-fed drip irrigation system allows you to efficiently and effectively water your plants while minimizing water waste and maximizing plant health.

Installing the water reservoir and connecting tubes
To set up a gravity-fed drip irrigation system, start by installing the water reservoir in a convenient location. Connect one end of the tubing to the bottom of the reservoir and use connectors to extend the tubing to your garden beds or plants.
Make sure to secure the tubing firmly using stakes or clips. If needed, you can also install additional tubes and emitters for different areas of your garden. Finally, adjust the flow rate by adding valves or regulators to control the amount of water reaching each plant.
Adjusting water flow and ensuring proper drainage
To adjust the water flow in a gravity-fed drip irrigation system, you can use valves or regulators. These devices allow you to control how much water is released from the system at any given time.
By adjusting the flow, you can ensure that your plants are getting just the right amount of water they need.
Proper drainage is also important in a gravity-fed drip irrigation system. This helps prevent water from pooling and causing damage to your plants or creating soggy soil conditions.
To ensure proper drainage, make sure that your tubing and connectors are free from obstructions or clogs. You can also elevate your raised beds slightly to encourage water to drain away from the plants.
Maintenance and Troubleshooting of Gravity-Fed Drip Irrigation
To keep your gravity-fed drip irrigation system running smoothly, regular maintenance and troubleshooting are essential. Check for clogs or leaks in the tubing, clean or replace filters as needed, and troubleshoot common issues like uneven water distribution.
