It's always nice to know what or how other operators do things around the pump. Be it mandated through SOP's, SOG's, personal preference or just because someone else said that we always do it this way.
Tank to pump. Open or closed?
Tank refill / re-cerculate. Open or closed?
When operating from a hydrant tank to pump open or closed?
Preference on which side LDH enters the pump. (Drivers, Passengers, Back, or Front)
Or any other pump little tid bit that you would like to add. If you could please state why for what you do, it might make more sense to others.
We keep all of ours closed,, when I get out with the pump in gear I already have pressure 50 lbs. at idle, pull tank suction turn up the throttle and I am flowing water. Now when drawing water from a source lake, port. pond I'm like a few others I lean against it and feel the flow of water in it, we have no hydrants and very rarely do water rely.
