Pump operating techniques
Always looking to hear how others operate. Here's the scenario:
Your engine (w/ electronic pressure gov., 1000 gals water onboard, and gated steamer connections) is setting up to work out of two fold-a-tanks. You'll need to supply 1-1 3/4" hand line (primary) @ 125psi and 1-2 1/2" handline (secondary) @ 50 psi. You will also have a 1 3/4" line going to a tank transfer, to move water from one tank to another, which will need to operate @ 100 psi once the 2 fold-a-tanks are set up. Let's not worry about friction losses. You may have to deal with not enough tankers to keep the tanks full initially (sporadic loads until more tankers arrive). I'd just like to hear how you would set and maintain all these different pressures as well managing your water supply. I realize I can't possible give 100% of the info you need, but hope that this is enough for some feedback.
Put the white stuff on the red stuff
Never speck a truck without class-A foam system on it. Virtually all of your water supply issues will be drastically reduced. The 1000 gallons on your truck will act like 3000 gallons.;)
