SpinNet and Vibro-Spray Sprinkler Selection & Sizing |
VISUALIZE THE GREENHOUSE
Evaluate the location of obstacles such as curtains or hanging baskets. Consider aisles and whether they can be wetted. Review cultural practices which might impact the height at which the sprinklers should be placed. |
SELECT THE SPRINKLER HEAD
Choose the SpinNet or Vibro-Spray Sprinkler for your application. All sprinkler solutions are based on an average sprinkler working pressure of 30 psi and three feet spacing between the sprinklers. |
SELECT THE SPRINKLER BASE
Netafim offers a selection of three bases to connect the sprinkler to the supply pipe.
- The 1/2" Adapter for connection to rigid pipe with 1/2" threaded connections is used with the Netafim Vibro-Spray Sprinkler.
- Dan Retrofit Adapter is used to connect Netafim SpinNet or Vibro-Spray Sprinklers to Dan fittings.
- Hanging Assembly is used for connection to Polyethylene (PE) Tubing
Supply Line with SpinNet and Vibro-Spray Sprinklers. It is available in 12", 24", 30", 36", and 48" lengths with an extension tubing piece for creating longer lengths.
Refer to SpinNet and Vibro-Spray Sprinkler Components section for part numbers. |

SIZE THE SPRINKLER SUPPLY PIPE
Use the POLY PIPE SIZING chart to select the correct supply pipe size. Low density polyethylene is strongly recommended. Netafim's reflective UV White™ PE Tubing is UV resistant, withstands heat, direct sun, and harsh chemicals, and reduces the water temperature. Please refer to the Greenhouse and Nursery Price Catalog for part numbers. |
SIZE THE DISTRIBUTOR AND MAINLINE
The remaining piping and system components are sized based upon the maximum flow they will receive. Use the FLOW PER SPRINKLER LINE chart to determine the flow of a single sprinkler supply pipe for the length of run in your design. If more than one sprinkler line will be operated at once, be sure to multiply the flow by the number of lines when sizing the system pipes and components. Pipe size recommendations are guidelines only. For distributor lines over 40 ft., mainlines over 100 ft. or when slopes are a factor, please contact Netafim USA Customer Service for further assistance. |

SIZE THE HEAD CONTROL COMPONENTS
The components should be sized according to the flow range shown in the FILTER, VALVE AND PRESSURE REGULATOR SIZING Chart below. The pipe connecting to the components can be a different size. Mixed sized pipes and components (e.g. 1" filter on 1 1/2" pipe) will have no negative effect on the operation of the system if properly sized by the flow range. |
STARTING UP A SYSTEM FOR THE FIRST TIME
The most important point to remember when starting up a new system is to flush the mainlines. Debris from construction can otherwise be washed into the sprinklers, resulting in plugging or improper operation. To properly flush a system, first connect all the pipes and hanging assemblies, except the Sprinklers with the Check Valves. Next, open the ends of the distributor line and the sprinkler supply pipes. Close them off, one by one, starting with the opening closest to the head control, and proceeding to the most distant opening. Only after complete flushing should the sprinklers with check valves be attached to the hanging assemblies. |
