My department strongly believes in the safety of the men and women inside a structure fire. After a couple near-misses, we addressed our issues by pumping in a similar method as yours with a slight variation. While the crew of Pumper A is hooking up to the hydrant, we have Pumper A engineer pump through a line we call "Truck to Truck" to Pumper B intake, that they had rolled back, and give Pumper B their tank water. This will is a more efficient way to give the interior crew additional water immediately until the crew of Pumper A hooks the hydrant up to Pumper A and then continues to feed Pumper B through the Truck to Truck line. This provides a safety measure for a complete pump failure along with providing the opportunity to pump multiple additional lines off of Pumper A. Give it a try and I'm sure you will find it more efficient as well as better safety for your crews.
If I'm understanding correctly, you are referring to Relay/Series Pumping. This is a great option and one that we use as well here in Dallas. Our SOPs do not dictate if we use a Dual or Series setup... so it's on the discretion of the Drivers to match the method to the scenario.
Part 25 in this series (next Monday), will cover what Pumping in Series/Relay looks like.
Appreciate the comment 🙏
Your videos are both informative and appreciated. Thank you for this. Valuable. What would you say to using a 5" to connect to pumper A's other side intake to Pumper Bs instead of the 3"? Thank you for your time.
5” is a great option.
Thanks for sharing! I’m wondering what the Engine A operator is doing to prepare for a failure? Is the pump engaged? Tank to pump open? The concept makes sense to me and I feel like it’s a solid practice, it’s just new to me :) thanks!
In a dual pumping set up, both engines are pumping and flowing water. They are just sharing a single hydrants pressure and volume.
By any chance have you, or do you plan on making any training videos about pumping to or through appliances and their friction loss associated with them?
Eg. foam pickup, wye, Siamese, thief, etc...
If you check out Therollsteady.com, under classes we have an engine pumping course (100% free). It's called Pump School with Rick Brewer. In the "Know Your Hose" section we discuss friction loss a bit.
It would be impossible to factor exact FL in every appliance out there. Best thing is to isolate the equipment you utilize on a regular basis (wye, inline system, etc) and then test each appliance using the same setup. We've done this just using our FoamPro or pitot tube from the water dept. This should get you rough numbers to use on a cheat sheet.
@@TheRollSteady Awesome thank you, also when you're writing with your marker on the glass, how are you doing that?
