Dry Fire Hydrant Design #38 - Suction Head Choice

President Mark Davis, December 31

We sometimes get asked about suction head choice on our bridge mount dry fire hydrants. In general, we prefer using a male suction head with polymer cap because the head is stored in a "facing up" position to prevent condensation forming ice in colder weather. The two photos showing a female head in this news story were taken in December 2020 in the mid-Atlantic area and show just a small build-up ... (Full Story & Photos)

Dry Fire Hydrant Design #37 - Strainer Installation Tip

President Mark Davis, December 24

Quite a bit of our work involves the evaluation of existing dry fire hydrants that have some problem. Often times the problem involves a damaged strainer and when that strainer is glued and part of a fixed installation....well, there is no easy way of making the repair...either drain the water source in order to access the strainer or send in a diver. The better choice is to plan accordingly ahead ... (Full Story & Photos)

Dry Fire Hydrant Design #36 - Bridge Mount Installation - Bel Air, Maryland

President Mark Davis, December 17

Another one of our bridge mount dry fire hydrant installations that we completed this Fall in Harford County, MD....this time on Thomas Run Road in Bel Air. The lift was really high at this location and required 20-feet of pipe...which is the physical limit of our design. The installation used our saddle-mount bracket design and an ETT suction head and stream strainer. When flow tested using Darlington's ... (Full Story & Photos)

Dry Fire Hydrant Design #35 - Box Culvert Installation - Whiteford, Maryland

President Mark Davis, December 10

We recently competed a somewhat unusual dry fire hydrant design and installation project in Harford County, Maryland where we modified our saddle-mount design to create a fixed-installation along the wing wall of a box culvert. The customer was interested in having the suction head within 10-ft reach of where a pumper would park, so we had to extend the pipe up a short incline toward the road.

In ... (Full Story & Photos)

Dry Fire Hydrant Design #34 - Bridge Mount Installation - Fallston, Maryland

President Mark Davis, December 03

In the last month or so we have been busy installing several of our bridge mount dry fire hydrants in Harford County, Maryland. The installation featured in this story is from the Fallston area of the County and is located on a County-owned bridge on Charles Street. The stream provided plenty of clean water and is known as a reliable year-round water source. The lift was a bit high (over 15 ft) ... (Full Story & Photos)

Suction Hose - #10 - Baldwinsville, NY

President Mark Davis, November 26

During our September 2020 drill in Baldwinsville, NY we were able to grab a couple of photos of Mottville Engine 2 using multiple suction hoses at the dump site. Of special note was the use of several lengths of suction hose to reach a dump tank set up to the rear of the rig. The dump tank had a side wall flange allowing for an easy connection and no "hose hump" over the tank frame. This set-up ... (Full Story & Photos)

Three lengths of suction hose allowed the pumper to draft from a dump tank positioned to the rear of the rig....using a single-lane configuration.

Dry Fire Hydrant Repair & Maintenance #11 - Bridge Mount Replacement

President Mark Davis, November 19

Back in September 2020, we posted a video clip about a leaking suction head on one of our bridge mount dry fire hydrants. A couple of weeks ago we finally got to make the repair and upgrade a couple of the components at the same time. A flow test was done using a 1500 gpm single-stage pumper and the rig was able to produce a 1,000+ gpm flow using two, TFT Blitzfire devices. The new stream strainer ... (Full Story & Photos)

Hauling Water - North Central Pennsylvania Style!

President Mark Davis, November 12

On Saturday and Sunday, November 7th and 8th about 50 folks from Montoursville and surrounding Lycoming County fire departments got together to refine their water hauling skills. On Sunday afternoon, the group worked to haul water for 2-hours uninterrupted using eleven tankers, four engines, and two fill sites. A peak flow of just over 1,000 gpm was achieved and the crews were able to build out a ... (Full Story & Photos)

Four pumpers and eleven tankers were used to haul water over the two-hour time period. Two fill sites were used
