Hello, my name is Scott Corum. Good afternoon. I am with Spring Foam Attic Fire Protection and Fire Alarm. Today, we're going to go through the basic operation of an electric fire pump. We'll also run through the maintenance and startup and shutdown procedures of the fire pump. What we have here today is our electric fire pump. We'll go through all the different valves that work with this fire pump. We've got a maintenance pump, which we'll consider as our Jockey pump. We also have our Jockey pump controller and our fire pump controller. We'll run through all these different tests and start off our fire pump.

This is in case our fire pump doesn't come on or is not working. City water can still flow through the bypass and reach the electric fire pump. For our Jockey pump, which is also connected to the underground, we have a supply valve and a discharge valve.

Throughout this presentation, we'll be looking at two sets of pressure gauges. The suction valve gauge will show us negative 30 if we start sucking the city water dry, up to 300 psi. The discharge valve gauge will show the pressure of the fire pump, which will be around 190 psi. These two gauges will help...
