SlimLine EZ Close™ Plastic Weight Assemblies
Netafim SlimLine EZ Close™ Weight Assemblies lower input costs and increase productivity. You’ll have cleaner, more efficient production of your hanging baskets.
CUT LABOR COSTS
The Netafim solution for hanging baskets will typically pay for itself in 100 to 120 days. Use the following chart to analyze your payback.
This feature allows the dripper assembly to be closed easily with one hand, preventing water and fertilizer from dripping on the plants or walkways below. With a quick glance, it’s easy to see if the assembly is open or closed.
HIGHER PERCENTAGE OF TOP QUALITY PLANTS
When every plant gets the same amount of water and fertilizer, exactly the same amount you specify, the result is a more uniform crop. The combination of pressure compensation and a built-in check valve results in water uniformity of 94%.
Regardless of the length of tube, all hanging basket drippers flow precisely the same. This means several lengths of drippers can be combined on the same line, with each dripper providing the same amount of water to both levels of baskets.
PREVENT ALGAE MESS ON YOUR FLOOR
Most old generation drippers soak the baskets to overflowing at the beginning of the line by the time the baskets at the end of the line receive adequate water. The result is both uneven watering of the plants and often a major algae mess on the floor from the overflowing baskets. Netafim drippers flow slowly and uniformly, so the soil media is easily wetted without any run-off around the edges of the basket.

DETERMINE THE DRIPPER SUPPLY PIPE SIZING
Using the top row of the WPCJ Dripper Supply Pipe Sizing Chart, select the dripper spacing to be used. By matching this to the length of the pipe column, the correct size Dripper Supply Pipe can be determined.
DETERMINE HOW MANY BASKETS CAN BE WATERED AT THE SAME TIME
Use the Zone Flow chart to help calculate how much water it takes to operate one zone of baskets. Select from the chart the number of baskets to be watered at the same time. Use the flow that results from this to determine the correct sizing for the pipe and control head components. Each dripper has a flow rate of 0.5 gallons per hours (GPH) nominal flow rate.
SELECT THE DISTRIBUTOR AND MAINLINE PIPE SIZES
Using the maximum flow demand from the largest zone or combination of zones which may be watered at the same time, you can size the Distributor and Mainline pipes from the Distributor and Mainline Pipe Sizing chart. Either PVC or polyethylene pipe can be used for the Distributor and Mainline. If PVC is used above ground, it should be painted to prevent light penetration, which can result in growth of algae within the pipe. This chart is appropriate for distributor lengths up to 40 feet and mainlines up to 100 feet. When slopes are a factor, when longer length pipes are needed, or for other special conditions, please consult a certified Netafim System Designer for assistance.
SELECT THE MAJOR SYSTEM COMPONENTS
Size the Control head (valve, filter and pressure regulator) based on Flow Demand determined in Step 2. It is very important to recognize the minimum flow for the pressure regulator. Make sure to size the pressure regulator by determining both the minimum and maximum number of baskets which may be watered at the same time. Use a 35 psi Low Flow Pressure Regulator with zones of 400 baskets or less. The size of the Control Head components should be determined by the flow demand and not the size of the pipe that connects to them. Mixed pipe sizes and components (e.g.1” filter on 1 ½” pipe) will have no negative effect on the operation of the system if properly sized by the flow demand.
