Dry Fire Hydrant Design #33 - Bridge Mount Installation - Darlington, Maryland

President Mark Davis, September 03

On August 30th we completed the flow test on another one of our bridge mount dry fire hydrant installations in Harford County, Maryland. This one was located in the Darlington area on Robinson Mill Road at Broad Creek. The installation was funded by local government as part of the upgrade to a new bridge installation. We used our angle-mount design and an ETT suction head and stream strainer. The ... (Full Story & Photos)

LDH Appliances #09 - When You Don't Have an LDH Discharge; Another Example

President Mark Davis, August 27

Another example of how to work with LDH when your pumper does not have a high-flow discharge. This photo from our 2012 Relay Pumping Seminar in Hyde Park, New York shows Fairview Engine 41-12 (1250 gpm) using two, short lengths of 3-inch hose to supply an LDH manifold that was supplying water to another engine 1000-feet up the road. Engine 41-12 did not have an LDH discharge. The drill was a 5000-ft ... (Full Story & Photos)

LDH Appliances #08 - When You Don't Have an LDH Discharge

President Mark Davis, August 20

Looking through some more photos...this time from our 2016 seminar in York County, Maine we found a couple good ones showing a pump operator overcoming not having a high-flow discharge...but needing to supply a 5-inch line. Nothing fancy to see here...just the use of a 2-1/2" x 2-1/2" x 5" clappered siamese to supply 1000 gpm through a 5-inch LDH line. The pumper was an older, 1250 gpm rig built ...

What's on Your Tanker? #24 - Ready for More Than Just Hauling Water

President Mark Davis, August 13

Looking back through some photos from our 2018 seminar in Windfall, Indiana we found some good ones of Kemptown Fire Rescue's Tanker 33; a 4,000-gallon tanker that is also set up to lay down a water blanket/spray in a field. The area protected by the tanker is quite flat and full of corn and other crop fields. When those fields are on fire, Tanker 33 can be used to support a perimeter fire line ... (Full Story & Photos)

Kemptown Tanker 33 not only can haul 4000 gallons to support water supply operations but it can also go off-road through a field and lay down a water blanket at a field fire.

Dry Fire Hydrant Design #32 - Bridge Mount Installation - Tuftonboro, New Hampshire

President Mark Davis, August 06

Earlier this week we were able to finish up the installation of our bridge mount dry fire hydrant in Tuftonboro, New Hampshire. The project had been in the works for about a year but installation was delayed due to the pandemic. The bridge is owned by the Town of Tuftonboro and the project was funded by the Tuftonboro Fire Rescue Department. Installation took about a day and the flow test proved ... (Full Story & Photos)

Dump Site Operations #20 - It Really Is About the Looks

President Mark Davis, July 30

Found some more photos while sitting here at home during the pandemic. This time from our 2018 seminar in West Carlisle, TX. The photos show a good looking jet siphon stream. How much is it flowing? What is the pressure needed to make it look like this? We don't know. We do know that the pump operator's goal is to "make it look like this." "This" generally is close to optimum flow in terms of pump ... (Full Story & Photos)

This 1000 gpm mini pumper did just fine drafting and loading the 1500-gal engine/tankers at this drill. The water was shallow but sufficient.

Drafting Tip #20 - Sometimes You Have to Use What You Got

President Mark Davis, July 23

We found this photo from our 2009 drill in New Windsor, MD. Not every fill site water supply is going to be perfect. This shallow stream had enough flow to support loading 1500-gallon engine tankers. It could not support the entire tanker shuttle operation; but it met the need for the smaller waterr haulers. A second site was used to load the large capacity tankers. The photo presents a good discussion ... (Full Story & Photos)

Above Ground Storage Tanks #01

President Mark Davis/Assistant Chief Jay Schwarz, July 16

We recently had some discussion in our Discussion Forum about the use of above ground storage tanks for fire protection water supplies. Assistant Chief Jay Schwarz from Bastrop County ESD#2 provided us some photos and info on the 10,000-gal above ground tank that they built to refill tenders.

According to AC Schwarz, "At Bastrop County ESD#2 station in Paige we have a tank setup to fill tenders. ... (Full Story & Photos)
