    <p>I decided to make this a 2nd thread, so as not to high jack the
      original theme.  <br>
    </p>
    <p>I have a question: it sounds like you are not spraying the roof,
      because its metal?  Isn't the plywood and rafters still vulnerable
      underneath the metal, or no? I'm concerned with large hot embers.<br>
    </p>
    <p>Can you post a couple pics of your sprayer install?  <br>
    </p>
    <p>2nd question:  what are the field results of these systems in
      actual fires?<br>
    </p>
    <p>Thanks,</p>
    <p>Ray<br>

          similar to what I designed and installed in 2001: <br>
          <br>
          I plumbed small irrigation sprayers every ~15' around the
          perimeter of my buildings<span> </span><span
            style="text-decoration: underline;">under the eaves</span>.
          This wets down the perimeter of the structures, particularly
          the combustion zone where the building meets the ground. Roof
          mounted sprayers leave a vulnerable dry gap between the drip
          edge and the building. Under eave sprayers wet this area and
          the siding.<br>
          <br>
          I have 40 of these sprayers which maxes out my well pump at 35
          PSI/~15 gallons a minute creating a rainstorm of water around
          the 8 buildings they are plumbed on. My GVFX-3648 is easily
          capable of operating the well pump during a grid outage.<br>
          <br>
          I also have window shutters and metal roofs.<br>
          <br>
          I use this to activate the solenoid valve from my phone if I
          am gone:<br>

          <br>
          It is controlled by this phone application:<br>

              style="text-decoration-thickness: initial;

          </a><br>
          It is perplexing why Cal Fire and others do not test and
          recommend these kinds of systems. The best answer I have been
          able to come up with is they fear people prepared like this
          would have a tendency to "stay and defend" their homes rather
          than evacuating.<br>
