The SprayNozzles are placed approximately 10 feet apart to get good area spray coverage. However, the SprayNozzles can be placed closer together if certain areas around the home need more water.
The ends of the Spray Nozzles will have irrigation type barbs (see photo below) to yield a tight fit to the hoses when clamped.
The Spray Nozzle ends are PVC pipe. If a PVC pipe is run along the roof gutter line of a house, the Spray Nozzle and PVC pipe can be connected at low cost as shown in the photo below. This roof gutter arrangement can augment the SprayHose and used to protect more of the roof from embers.
The PVC is a permanent installation while the hose should not be left in place all of the time where it might be damaged by lawn mowers, etc.
