Hello

A spray system surrounds a home to stop embers & grassfires.

The figure above shows a home surrounded by an In-Ground Spray System 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 1000 gallon 

above-ground tank. Water from a household spigot is not nearly enough to protect a home. 


Note that the shape of the spray from each nozzle is actually a triangle.

The full patent can be seen after the photos below.

Unlike rotary sprinklers, there are no moving parts.


These inventions are protected by 

US Patents 7,819,345,  7,942,350 and 9,561,393, 11,203,023, 

and Canadian patents 2,693,158, and 2,891,833 and several 

pending US patents.






Spray Nozzle in stainless steel cradle for protection

Both are placed underground. The cradle protects the Nozzle from a heavy lawn maintenance vehicles.

This nozzle is made from only PVC pieces. This is the lowest cost method of building a nozzle. PVC could be damaged by a fire but the cradle will protect it.


Other pages of this website will show a nozzle that has an outer layer of a fire resistant hose. That nozzle is designed to be placed above ground when a fire is coming. The nozzles will be 10 feet apart and connected by 

2.5 inch fire hose that is resistant to fire. The cost of the cradle is not yet known. 

Hinged stainless steel lid protecting spray nozzle.

PVC pipe can be used to supply water to all nozzles.

This product is US Patent Pending.

It will connect with other spray nozzles via underground PVC.

The top of the cradle will be at ground level. The cradle is not harmed by the weight of an automobile. A stainless steel zip tie is shown on the left half of the cradle.

It is used to secure the nozzle in the cradle so that the desired spray angle is maintained.

Two stainless zip ties will be used.

Above is smaller & lower cost spray nozzle.

It has the same spray pattern as the larger nozzle described earlier,

but it costs less and delivers less water. It was created to confine prescribed fires.

This will be shown later on this site. 

However, this smaller and lower cost nozzle can be used for the lowest

possible cost home protection system.
