Let’s face it: Pump testing is a long, arduous, and thankless job that has to be done on a regular basis.
While many fire departments perform this task on a yearly basis on their own, often using a training facility with a pump test pit or heading to a surface water source, other departments opt to have a mobile pump testing company come to their locations and pump test apparatus in their home stations.
Pump Testing Units
Gary Weis, chief operating officer of Weis Fire & Safety Equipment and inventor of the Draft Commander 3000 A/T Mobile Fire Pump Testing and Training Unit, says many pump test pits installed at training facilities years ago are now obsolete. “Some fire pumps today perform at 2,000 gallons per minute (gpm), and a lot of those older pits won’t function at that rate,” Weis says. “Also, the water in those pits often is dirty from runoff and sediment, which can allow grit and other solids to get into the pump, damaging it by sandblasting the interior. Our Draft Commander pump tests only with clean water that we recycle.”
The Draft Commander has a 3,000-gallon T-shaped reservoir made of one-inch polypropylene that is attached to a heavy-duty DOT-rated transporter so it can’t twist or flex. The drafting pit section of the reservoir has four antiswirl plates and a water temperature gauge to monitor the water temperature. The Draft Commander is fitted with drafting tubes and swivels, hard suction hose, aluminum inlet manifolds for flowing water and pitot gpm readings, a pump testing monitor station, a handheld monitor, and storage areas for hose and equipment.

Weis says many of the problems he sees during pump tests can be traced back to maintenance issues. “When we perform pump tests, we have numerous tank-to-pump valves leak,” Weis says. “Also, a lot of discharge valves leak. People don’t realize the wear and tear that valves take, and we also see pump seal rings wearing out from getting sand and grit in them. We have a 64-point checklist to review during a pump test, and it covers everything from A to Z.”
Dan Kreikemeier, president of Danko Emergency Equipment, says his company makes the Draftmaster Pump Tester and Trainer. The Draftmaster has a 2,400-gallon UPF water tank and can handle pumps with capacities up to 2,500 gpm. The unit has a forced-air water cooling fan system, stainless steel manifold, stainless steel diffuser with a flowmeter, hard suction hoses, adapters, and an operator’s panel-all on a tandem-axle trailer with a 7,000-pound weight rating and DOT trailer brakes.
