$2000 & $4000 automatic spray systems can protect a home from grassfires and embers

  • The following section describes an above ground hose system that costs around $4000 for a medium size house. A system that is buried underground will cost more.
  • The section that follows this section described a system for small homes and house trailers. That system costs around $2000.

The figure above shows a home surrounded by an AUTOMATIC Spray System that is putting up a wall of water that can stop a grassfire and embers. The water can come from a pool or a cistern or an above-ground tank.

At this home, a 600 gallon plastic above ground tank supplies the water. (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.

Unlike rotary sprinklers, there are no moving parts.


When told to evacuate, the homeowner starts a pump and LEAVES.

The system will automatically start spraying when the fire is near.


The system was donated, by me, to the fire department in Mansfield WA, and was installed by me and by members of the local fire department.


The lowest cost version of the system uses hose to connect nozzles which are 10 ft apart. 


The next section shows how stainless steel cradles can be used to bury the system in the ground. The nozzles are then connected by underground PVC pipe.


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.

$2000 SYSTEM

  • A very low cost pump is driving the flow to the four spray nozzles. The nozzles span 50 feet which can protect a smaller home or house trailer. The homeowner must supply a water tank. It is easily made from plywood and plastic tarp.

Spray Nozzle in stainless steel cradle for protection

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

Hinged stainless steel lid protecting spray nozzle.

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


side view of spray nozzle in cradle

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.

The above us patent describes my spray nozzle invention

The nozzle creates a triangular shaped spray in width and depth.

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.
