above, the large Spray Nozzle with fire resistant hose layer
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 large nozzle has not failed at 100 psi.
The ends of the nozzle are 2 inch PVC which have 1/2 inch wide notches for attaching 2.5 inch hose with hose clamps.
Hose barbs were tried on the nozzle ends, but did not work as well as the notches. Hose barbs can be requested instead of notches.
above photo is a spray nozzle conected to hoses
The Spray Nozzle ends are attached to hose with the hose clamps.
If a PVC pipe is run along the roof gutter line of a house, the Spray Nozzle and PVC pipe can be connected together, 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 roof gutter is a permanent installation, while the hose connected nozzles should not be left in place all of the time where it might be damaged by lawn mowers, etc.
The PVC ends of the spray nozzles can be glued to the PVC 10 ft sections by PVC repair couplers. This does not allow for changing the angle of the spray once the parts are glued.
many hose colors are available & PvC can be painted
