The figure above shows a home surrounded by a SprayHose line that is putting up a wall of water to stop a grassfire and embers. The water can come from a pool or a cistern or a large above ground tank. Water from a household spigot is not nearly enough to protect a home.
These inventions are protected by
US Patents 7,819,345, 7,942,350 and 9,561,393, and Canadian patents 2,693,158, and 2,891,833 and several pending patents.
above, the center is spray nozzle,the right & left are hose
Note the two holes in the center of the SprayNozzle.
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.
above photo is a spray nozzle conected to hoses
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.
many hose colors are available & PvC can be painted
The sprayNozzles must be held at a chosen angle for spray
This is achieved by using the clamps shown which are sold at Harbor Freight Tools.
