Understanding the proper installation and application of drainage and fertigation systems is essential for maximizing efficiency and long-term performance. Among the available solutions, the NDS EZ Flow system stands out for its ease of use, durability, and adaptability to various environments. This article provides a detailed guide on how to install and use the EZ Flow system for drainage and fertigation purposes, based on official specifications, user experiences, and manufacturer guidelines.
Overview of the EZ Flow System
The NDS EZ Flow system is a pre-constructed drainage solution designed for residential and light commercial use. It features a central 4-inch perforated corrugated polyethylene pipe surrounded by expanded polystyrene aggregate, all enclosed in a geotextile mesh. This design offers several advantages over traditional drainage systems, including reduced labor, faster installation, and increased efficiency due to the unique material composition.
The system is suitable for non-load-bearing applications and can be installed in trenches with 12 inches of compacted fill over the bundles. It is not designed to support live-load traffic, such as roadways, driveways, or parking areas. The EZ Flow system is available in different pipe sizes (3 in., 4 in., and 6 in. diameters) and is compatible with standard couplers and fittings.
For fertigation applications, the EZ-Flow product line offers a range of dispensing systems that automate the process of mixing fertilizers with irrigation water. These systems are ideal for homeowners, landscapers, and commercial agricultural operations seeking to optimize plant health and reduce water usage.
Installation Process for Drainage Systems
Step 1: Trench Preparation
Before installing the NDS EZ Flow drainage system, it is essential to prepare the trench according to the manufacturer’s specifications. The trench should be dug to a depth that accommodates the drainage bundle and at least 6 inches of soil cover. The maximum depth for burial is 8 feet; for deeper installations, it is recommended to contact NDS Technical Services for guidance.
It is important to ensure that the trench is level and free of sharp objects that could damage the corrugated polyethylene pipe. A minimum of 2 inches of sand or pea gravel should be placed at the base of the trench to provide a stable foundation for the drainage system.
Step 2: Placement of the Drainage Bundle
Once the trench is prepared, the EZ Flow drainage bundle can be placed inside. The system is designed to be lightweight and easy to handle, making it possible to carry individual sections into the trench manually. This eliminates the need for heavy machinery, reducing labor costs and installation time.
The geotextile mesh surrounding the bundle should be fully intact to prevent soil infiltration while allowing water to flow through the perforated pipe. Care should be taken to avoid damaging the mesh during placement.
Step 3: Connecting the Drainage Lines
If multiple drainage bundles are being installed, they should be connected using EZflow couplers or commercially available fittings. These connections allow for compatibility with various pipe sizes and brands, ensuring a secure and leak-free installation.
It is important to note that the corrugated polyethylene pipe has limitations in terms of contouring. While aggregate-only bundles can make sharp bends (such as 90-degree corners), pipe bundles require internal connection fittings for bends greater than 45 degrees to maintain structural integrity and prevent leaks.
Step 4: Covering and Finishing
After the drainage bundle is in place and all connections are secure, the trench should be backfilled with compacted soil. A minimum of 6 inches of soil cover is required to protect the system from physical damage and ensure proper function. The soil should be compacted in layers to prevent settling, which could cause the drainage system to shift or become misaligned.
The system should be designed to direct water away from the structure, ideally daylighting to a sump or other discharge point. This prevents water accumulation and reduces the risk of basement flooding or foundation damage.
Application in Fertigation Systems
In addition to its use in drainage, the EZ Flow system is also available in a fertigation version that automates the process of applying liquid fertilizers to plants. This system is particularly useful for homeowners with drip irrigation systems who want to enhance plant growth without the need for manual mixing or application.
Step 1: Selecting the Right Fertigation Model
EZ-Flow offers several models of fertigation systems, including inline dispensers and mainline units. The inline models are suitable for small to medium-sized gardens or patios, while the mainline models are designed for larger areas, such as farms, nurseries, and sporting fields.
When selecting a model, it is important to consider the size of the area to be fertilized, the frequency of watering, and the type of plants being grown. For example, a 20-20-20 fertilizer mix is commonly used for flowering plants, while organic iron and fish emulsions are preferred for revitalizing damaged lawns or gardens.
Step 2: Connecting the Fertigation Unit
The fertigation unit should be installed at the point where the irrigation system connects to the water supply. This allows the unit to inject the fertilizer solution directly into the irrigation lines. The unit is typically attached to the faucet end of the system and requires no additional power source, making it easy to install and operate.
It is important to follow the manufacturer’s instructions for setting up the unit, including adjusting the flow rate and ensuring that the fertilizer tank is properly filled. A wide-mouthed funnel is recommended for filling the tank to prevent spills and mess.
Step 3: Programming and Operation
Once the fertigation unit is installed, it can be programmed to dispense the fertilizer at specific intervals. This ensures that the plants receive a consistent and even supply of nutrients, promoting healthy growth and reducing the need for manual intervention.
Users have reported that the system is easy to use and requires minimal maintenance. For example, one user noted that the system worked flawlessly on the first use and provided the expected amount of fertilizer within the calculated time period. Another user mentioned that the system has no tricky or fragile parts, suggesting that it is durable and long-lasting.
Step 4: Monitoring and Adjustments
After the system is in operation, it is important to monitor its performance and make adjustments as needed. This includes checking the flow rate, ensuring that the fertilizer tank is not empty, and inspecting the irrigation lines for clogs or leaks.
Some users have found that using a larger unit reduces the frequency of refilling, making it more convenient for large or busy properties. Additionally, some models allow for the use of different types of liquid fertilizers, giving users more flexibility in their gardening or landscaping practices.
Key Considerations for Installation and Use
When installing or using the NDS EZ Flow system, there are several key considerations to keep in mind to ensure optimal performance and longevity.
Environmental and Temperature Resistance
The system is designed to withstand extreme temperatures, ranging from -108°F to +175°F. This makes it suitable for use in a wide range of climates, including cold regions where freezing temperatures are common. The expanded polystyrene aggregate does not become brittle in subzero conditions, eliminating the need for additional protective measures or deeper burial in colder areas.
Durability and Pest Resistance
The geotextile mesh used in the system is stronger and more durable than traditional filter sheets, providing better protection against soil infiltration and extending the system's lifespan. Additionally, the polystyrene aggregate offers no nutritional value to pests, making it resistant to damage from burrowing rodents and other animals.
Compatibility and Customization
The system is compatible with a variety of fittings and couplers, allowing for easy integration with existing drainage or irrigation systems. It can be customized to suit different applications, whether it is a small residential garden or a large commercial property.
