3-4 in Trash Pump

The 3-4 in Trash Pump is appropriate for trenches, small excavations, and foundation pits where rain or groundwater seepage produces moderate inflow that a smaller pump cannot sustain. When flow demands are lighter—such as a narrow trench in stable soil—the 2-3 in Trash Pump offers easier handling and lower fuel consumption. For larger excavations, dewatering sumps, or sites with heavy stormwater runoff, the 4-6 in Trash Pump provides the additional capacity needed to prevent flooding. Match pump size to the expected inflow rate and the duration of pumping required.

• Dewatering a utility trench during a multi-day rain event
• Keeping a small building foundation excavation dry while crews pour footings
• Draining stormwater accumulation from a retention pond or low spot on a grading site
• Managing groundwater seepage in a shallow sewer-line dig through saturated soil
• Pumping out a flooded construction access road or staging area after heavy rainfall

• Position pump on stable, level ground and secure suction strainer below water surface to prevent air ingestion
• Maintain adequate ventilation around engine exhaust; never operate in enclosed spaces
• Inspect hoses and couplings for secure fit under pressure; unsecured discharge lines can whip and cause injury
• Monitor fuel level and engine temperature during extended runs; allow engine to cool before refueling

• Compact enough for bed-mount in a pickup truck or small utility trailer
• Most units feature lifting handles or roll-cage frames for two-person loading
• Standard ball-hitch utility trailer sufficient for towing to site

• Typically powered by gasoline or diesel engines in the 5–8 hp range
• Self-contained fuel tank supports several hours of continuous operation between refills
• No external electrical supply required; engine-driven design for remote or off-grid sites
