Product Description

Overhead spray-lines are the simplest and most cost-effective method of watering your greenhouse crops. All the pipework and sprinklers are above head height, thus keeping them out if the way and free from accidental damage. In order to achieve the most uniform and efficient coverage you should use a good quality sprinkler assembly.A choice of spray-line connectors available, M11 or 3/8”WW threaded for grey PVC pipe or a barbed PE adaptor for black polyethylene pipe.


We use M11 pipe andconnectors as standard.


The use of drop-tubes ensures all the sprinklers hang true to give optimum performance.  They also keep the spray-line dry to prevent dripping.


Anti-drip valves give instant, simultaneous start up and shut off, and prevent the water in the spray-line dribbling out after irrigation has finished.


We’ve described our spray nozzles by their suitability for use in a particular polytunnel width - based on a twin-line overhead system.  If you can’t decide which spray nozzle option is the best for your particular polytunnel/glasshouse then please speak with one of our irrigation advisers. Ein Dor and Netafim parts are all 6mm push-fit and fully interchangeable.
