What's On Your Tanker #60? - More Simple Things

President Mark Davis, June 19

During our seminar in Waverly, NY earlier this month we had the pleasure of coming across and using Litchfield Tanker 26T1. The older, locally-made rig repurposed a stainless steel milk tank and was set up to really just haul water. The 2200-gallon tanker was equipped with a 200 gpm pump and carried a 2100 gallon dump tank...more interestingly though was the site glass for tank level monitoring. ... (Full Story & Photos)

Dry Hydrant Design #73 - Falmouth, Michigan

President Mark Davis, May 29

On May 22nd we completed our first, bridge-mount dry fire hydrant installation in Michigan thanks to Chief Carl Fisher and the folks at the Clam Union Fire Department.

LDH Appliances #14 - Threaded Suction Intake Control Valve

President Mark Davis, May 15

A recent discussion on our Facebook page about suction inlet control valves reminded us of a couple photos we found while looking back on our 2011 seminar in DeKalb County, Alabama. The two photos are pretty simple but show what we believe is a best practice of having a threaded connection on the inlet side of an external control valve if the department plans on drafting through the valve.
