Howdy Folks!
Recently have taken on the responsibilities on getting into a driving rotation. In my initial pump training I was told to leave "tank to pump" valve open when running off a hydrant just in case we "lose the hydrant". Made sense to me at the time. Fast forward 3 yrs later I was doing my pump ops cert and was told not to leave the tank to pump valve open. I explained that I was taught to leave it open in case I lost the hydrant. Instructor noted that in his 20+ yrs hes never had a hydrant malfunction on him, (were in a large urban setting)
My question is does anyone know of any reasons why we would close the tank suction?
