" such that it could -- before we talk about. The particulars of us sprinkler system and how it's installed communal a little background on sprinklers to bottom up. A gentleman in Frederick and August started back in 1850. He was contractors to put in sprinkler systems and buildings old noble Providence. So it originates here in the United States and Providence, Rhode Island they. Piano manufacturer. Actually was word of all fire in his buildings that we contractor with murder and helped put the systems and and that's offer you know -- started that was there initiating. No corporation great let's talk about what you've done here for us because we've got a rather unusual building it cut specialty storage barn. Gonna have automobiles. In this part of it -- in the other part of it how do you you know how do you approached this from the point of view design. -- done as we've provided a system that takes into consideration possibility -- maybe freezing in here in the may not be. So the system is designed as such that it filled -- Pressure which hold that water so it is an enormous fight that you got a weird not hold water. A -- water up to this point. Are held back by this clapper. Okay normally there would be air pressure that holds back that water pressure how to meet here hold back the water well it's a system of physics. One pound of Eric -- execs found the water just from it was called differential size of the -- so okay. -- an anti money went in here is here. Lawless piping. If you got a fire in here hi how does -- how to get activated. What happens and we really start -- put it right there. And it's recorded which Pepsi -- sprinkler has a liquid that expands upon heat in this particular scenario 155 degrees -- This would break. This'll but would fall off the water would come out -- in this case in this building we have here pressure there. So when this all fuses out on fire -- The air would flow and directly behind that the water flow now does that mean -- it. All of a sprinkler heads go off -- I have a little fire over here in one corner of the building. Only those sprinklers that are in the area of the fire origin operate now what are we doing up here he's -- basically putting together -- couple. Couple -- to talk to piping systems as a branch lines which comes off a feed line or pre name. The system the size smaller original for a way provisional use much water from the capital so that and it just dead ends at that point over there correct. And these these crackers and then. Position to cover certain amount of square foot area based on the hazardous those building the potential for fire in this building. As far as the hazard is much higher here in the would be sent residents -- you're storing automobiles they have gasoline and you're storing boats they're made out of fiberglass. And other man made. Flammable products which is why we have -- such large diameter mainstream right and now the pipe being here. For a two inch pipe -- looks relatively light. Physicists known as a credible than all the so called excel. It's been galvanized on the fixture has made with a high tensile strength steel when we make it that way. We actually reduce the wall -- slightly. Now as compared to say something Alex and forty OK it allows us more efficiency ninety of the pipe with the larger we can make quite fast their nuclear production. So it's -- insurance but I can't wait to see it finished --"
