CAT CLASS: HQ-10793

Up to 2 in Trash Pump

Up to 2 in trash pumps are the lightest class of dewatering pumps designed to handle solids-laden water, suited for light dewatering of small pits or flooded floors with some debris. These units are one-man portable, typically featuring 1-inch discharge ports and flows up to 27 gpm. They occupy the smallest rung on the trash pump ladder, below the 2–3 in class used for higher-volume applications.

Key specifications

Specification	Typical range	What it means
Discharge port diameter	1 in (25.4 mm)	Defines the maximum solids size that can pass and the hose connection standard.
Flow rate	14–27 gpm	Volume capacity for this size class, sufficient for small-scale dewatering tasks.

How to choose

This size class is appropriate for small-scale dewatering where portability by a single operator is essential and flow demands remain below 30 gpm — typical scenarios include flooded mechanical rooms, shallow excavations, and residential basement flooding with light debris. The limited discharge diameter restricts both flow capacity and maximum solids size. For higher volumes, faster drawdown, or debris larger than approximately ¾ inch, the 2–3 in Trash Pump class delivers substantially greater flow (often exceeding 50 gpm) and handles larger solids without clogging.

What this size handles

Flooded basement or crawl space with mud and small debris
Shallow utility trench dewatering on residential sites
Small sump pit or elevator shaft with intermittent inflow
Emergency water removal from mechanical rooms or storage areas
Pond draining or fountain maintenance with silt present

Safety & operation

Ensure suction screen is clear and discharge line is secured to prevent whipping under pressure
Operate on stable footing; pump housings can become slippery when wet
Maintain ventilation when running gasoline engines indoors or in confined spaces
Verify electrical units are GFCI-protected when operating in wet environments

Transport & logistics

One-person carry by handle; no trailer or hoist required
Fits in the bed of a pickup truck or rear cargo area of a service van
Compact footprint allows storage in a job-box or gang box

Power & supply

Electric models operate on standard 115 V single-phase circuits, drawing under 15 amps
Gasoline-powered variants use small air-cooled engines with integral fuel tanks

Frequently asked

What is the largest solid this size class can pass?

With a 1-inch discharge port, solids typically up to ¾ inch can pass, though manufacturer specifications vary. Larger debris will clog the impeller or screen.

How quickly can an up-to-2-inch pump drain a typical residential basement?

At 20–25 gpm, expect roughly 4–6 hours to remove 6 inches of water from a 1,000-square-foot area, assuming steady inflow is controlled.

When does a 2–3 inch trash pump become necessary?

Move up when flow exceeds 30 gpm, debris diameter approaches 1 inch or larger, or drawdown time for the application becomes impractical with sub-2-inch capacity.
