LANCHEZ 1.6HP Sump Pump
The LANCHEZ model uses a 1.6 HP full stainless steel housing to deliver strong suction, with a maximum flow of 5500 GPH and a head of up to 30 ft. The high baseplate design aids particle passage up to 4/5 inch, making it adaptable to sewage-like conditions and preventing clog-related downtime.
Automatic operation is driven by a float switch that starts at about 5.3 inches; it can also be operated manually when the switch is upright. A built-in thermal overload protector guards against overheating during extended use. The unit includes a 1-1/2 inch discharge plus 3/4 inch and other adapters, and a 16 ft power cord provides flexible placement. It’s well suited for basements, pools, and flooded pits where debris is present.
- Stainless steel housing for damp environments
- Automatic float switch with thermal protection
- Solids up to 4/5 inch allowed
- Multiple discharge adapters included
6699 Submersible Sump Pump
The 6699 model is a high-capacity submersible pump rated at 7000 GPH with a head up to 30 ft, powered by a 1.5HP motor. Its stainless steel housing and hi-impact plastic construction deliver durability in damp, dirty environments. A 16 ft power cord enables flexible placement away from outlets, reducing the need for extension cords.
Automatic float switching starts and stops the pump with changing water levels; if you manually keep the float elevated, the unit can operate with the lowest intake around 2 inches. This flexibility is useful during installations where water levels fluctuate rapidly, such as during heavy rains or groundwater rise.
- Automatic float switch for reliable cycling
- Stainless steel housing with durable plastics
- 16 ft power cord for easy reach
- High-flow, high-head performance

Buying Guide
When choosing a sump pump for a high water table, prioritize head height and flow together with durability and ease of use. In flood-prone basements, a pump that can push water up to about 30 ft or more ensures effective drainage even when water pressure is high. High GPH ratings are valuable, but they must be paired with sufficient head to reach the discharge point.
Material matters. Stainless steel housings excel in damp environments and resist corrosion, while thermoplastic designs offer lighter weight and strong durability at a lower cost. For dirty or debris-laden water, select models with solids handling or mesh screens to protect the impeller and extend life. Automatic operation via float switches or electronic sensors reduces the need for manual intervention during storms.
Discharge compatibility is essential. Most home setups use a 1-1/2 inch outlet, with adapters available for 1″ or 1-1/4″ lines. Cord length influences placement—longer cords provide flexibility but require safe routing. Maintenance considerations include accessible impeller design, easy cleaning, and a design that resists clogs in debris-rich water.
From a practical standpoint, balance performance with installation needs. For a high water table, models like the LANCHEZ or 6699 offer high flows and solid lift, while Limodot, MEDAS, and FOTING provide reliable mid- to high-head capacity with easier portability. Think about the typical water source (clean or dirty), the space available for the unit, and how often you anticipate use during extreme weather.
