Dry Fire Hydrant Repair & Maintenance 01 - Replacing a Suction Head

President Mark Davis, August 28

Part of a FD's water supply delivery program is the annual inspection and flow testing of dry fire hydrants. We recently had the opportunity to work with the folks at the Gamber Community VFC to replace the suction head on their 40,000-gallon underground fire protection water storage tank located on their property. The existing suction head had developed an air leak and the decision was made to just ... (Full Story & Photos)

When installed many years ago, the 4-1/2" suction fitting was the standard on these underground storage tanks - yet few companies used 4-1/2" suction hose. Today's pumpers most all use 6" suction hose - the changeover to that size suction head increases the size of the opening and eliminates the need for a bell reducer.

New Product: Vacuum Gauge Displays Lift in Feet

President Mark Davis, August 21

The folks at Winfield VFD (Maryland) recently had their Trident Automatic Air Primer upgraded to include a new control panel that uses a vacuum gauge graduated in "feet" of lift instead of the traditional inches of mercury. The new style gauge makes it much easier for the pump operator to assess lift conditions during drafting operations - as well as troubleshoot issues that can occur under vacuum ...

Hauling Water in South Onondaga, New York

President Mark Davis, August 04

Chief Erik Nelson and the folks at the South Onondaga VFD (New York) hosted our 2-day Rural Water Supply Operations Seminar on August 2nd and 3rd. As usual, the seminar culminated with a 2-hour tanker shuttle operation. Crews worked really hard to "beat the clock" and get the initial flow going without the use of a nurse tanker - and they were successful! An average flow of 792 gpm was attained ... (Full Story & Photos)

Engine 6 eventually used three suction intakes to support the operation: two 6-inch lines and one 2-1/2-inch suction line.

Drafting Tip #06 - Use Dual Suctions to Increase Pump Capacity

President Mark Davis, July 31

A very good way to increase the pump capacity of pumper (one that is rated 1500 gpm or less) is to draft using two suction inlets. Pumpers that have midship mounted pumps rated 1,500 gpm or less are usually rated using only one of their side suction inlets. By using both suction inlets, capacity can be significantly increased as long as the motor can produce sufficient torque to drive the pump. For ... (Full Story & Photos)

The 1000 GPM Club

President Mark Davis, July 17

We are pleased to announce that we will begin recognizing those folks who can deliver 1,000 gpm (or more) during the second hour of our 2-hour "ISO" water supply drill. After having delivered more than 40 of our 2-day Rural Water Supply Operations Seminars over the last five years - we have found the "1000 gpm" flow rate to be a special target that only a few groups have been able to reach AND sustain ...

Know Your Roots!

President Mark Davis, July 10

A couple of years ago we got called to repair a broken suction pipe on a buried underground tank that held fire protection water for a nearby commercial property. The pipe on the tank had been cracked for a few years and the local FD was having trouble obtaining a draft during their annual flow tests. When the pipe got struck by a tractor pushing snow - then it was time to call us for repair.

As ... (Full Story & Photos)
