Running a hydroponic system in shallow reservoirs or tight spaces? The EcoPlus Convertible Bottom Draw Water Pump solves the common problem of pumps failing in low water conditions. With its innovative bottom draw inlet design, this pump operates efficiently in less than 1/2 inch of water—eliminating dry-run failures and extending equipment life. The 265 GPH flow rate delivers reliable circulation for small to medium hydroponic setups; for larger reservoirs, the EcoPlus 585 GPH bottom draw pump provides increased volume while maintaining the same low-profile benefits.
The EcoPlus Convertible Bottom Draw Pump represents a first-of-its-kind design in hydroponic water circulation. The patent-pending convertible outlet system (US Patent Pending No. 14/642,557) allows users to switch between horizontal and vertical water flow directions without purchasing multiple pumps. This eliminates the guesswork of choosing the right pump orientation and provides maximum installation flexibility whether you're setting up DWC systems, nutrient film technique (NFT) channels, or recirculating drip systems.
Built for the demanding conditions of continuous hydroponic operation, this submersible pump combines energy efficiency with consistent performance. The bottom draw inlet ensures the pump captures water from the lowest point in your reservoir, maintaining prime even as water levels fluctuate during feeding cycles. To maintain ideal nutrient temperatures, this pump pairs perfectly with an EcoPlus 1/10 HP water chiller in small-scale setups, making integration straightforward for both hobbyist growers and commercial operations.

The convertible outlet fitting can be repositioned by removing the existing fitting and rotating it to your desired orientation before reattaching. Detailed step-by-step instructions with diagrams are provided in the included Fitting Guide manual. The process takes less than a minute and requires no special tools.
Yes, the EcoPlus Convertible Bottom Draw Pump is designed for continuous submersible operation in hydroponic systems. The energy-efficient motor and durable construction support 24/7 operation when fully submerged. Ensure the pump remains underwater during use and maintain adequate water levels above the minimum 1/2 inch requirement for optimal performance.
The interchangeable outlet fittings accommodate standard hydroponic tubing sizes commonly used in nutrient delivery systems. Refer to the Fitting Guide manual for specific diameter measurements and compatibility charts. The universal design ensures compatibility with most common hydroponic tubing available from major suppliers.
Absolutely—this is exactly what the bottom draw inlet design was created for. The pump operates efficiently in less than 1/2 inch of water, making it ideal for shallow flood-and-drain tables, low-profile reservoirs, and systems where water levels fluctuate significantly. The bottom draw inlet ensures the pump continues circulating water even when levels drop below what traditional pumps require.
The 265 GPH flow rate is well-suited for small to medium hydroponic setups including DWC buckets, small NFT channels, and recirculating drip systems with 1-6 plant sites. For larger commercial operations or systems requiring higher circulation rates, consider the higher GPH models like the EcoPlus 730 GPH bottom draw pump. Calculate your system's total volume and desired turnover rate to determine if this pump meets your circulation requirements.
Yes, the EcoPlus Convertible Bottom Draw Pump is designed specifically for hydroponic applications and handles standard nutrient solutions without issue. The pump materials are compatible with common fertilizer formulations used in hydroponic growing. Regular maintenance including periodic cleaning helps ensure longevity; using an EcoPlus pump filter bag can help prevent debris from entering the motor when circulating nutrient-rich water.
Routine maintenance includes inspecting and cleaning the inlet screen monthly to prevent debris buildup that could restrict flow. Periodically remove the pump from the reservoir and rinse away any salt deposits or organic matter that may accumulate. For detailed maintenance schedules and procedures, consult the Installation Instructions manual included with your pump.
This model is designed for submersible operation only and must remain fully underwater during use. If you require a pump that can function outside of the reservoir, the EcoPlus Eco 264 is an excellent fixed-flow alternative with inline capabilities. Operating the bottom draw model out of water will cause overheating and permanent damage not covered by warranty.
