A powerful automatic pump built for fast drainage and demanding water transfer
Introduction
Large volumes of unwanted water can quickly turn from an inconvenience into a serious problem. Flooded basements, overflowing pools, waterlogged gardens, and storm-related cellar flooding require fast, dependable solutions. In these situations, a low-powered utility pump may not be enough. What homeowners and property managers need is a high-capacity pump that can move water quickly, safely, and with minimal supervision.
The PHLEX PRO 1HP Submersible Water Pump is designed for exactly these demanding scenarios. With a high flow rate of up to 5300 gallons per hour, automatic float switch operation, and the ability to handle both clean and dirty water, this pump is built for heavy-duty residential and light commercial use.
In this in-depth PHLEX PRO 1HP submersible water pump review, we examine its real-world performance, construction quality, safety systems, and practical applications. This article provides a complete, easy-to-understand overview for anyone considering a high-flow sump and transfer pump.
Product Overview
The PHLEX PRO submersible pump is a 1 horsepower electric water transfer pump designed to operate fully submerged. Unlike basic utility pumps, it combines high flow capacity with intelligent switching between clean and dirty water operation.
The pump is equipped with an automatic float switch, allowing it to turn on and off based on water level. It also supports manual operation for continuous pumping when needed. With its oil-free PSC motor, corrosion-resistant thermoplastic housing, and removable base, this pump is engineered for reliability, safety, and ease of maintenance.

Build Quality and Materials
The PHLEX PRO pump uses a sealed thermoplastic housing designed to withstand constant exposure to water. Thermoplastic materials such as polypropylene and PVC are widely used in submersible pumps because they resist corrosion, chemical exposure, and mineral buildup.
Construction Highlights
- Corrosion-resistant outer shell
- Fully sealed internal motor chamber
- Durable base structure for submerged stability
- Removable bottom for easy cleaning
This design ensures long-term reliability, even when the pump is used in dirty or sediment-heavy water.
High-Performance Pumping Power
At the core of this pump is a 1HP oil-free PSC motor, delivering impressive pumping power for residential and utility applications. With a flow rate of 5300 gallons per hour, the pump can rapidly remove large volumes of water.
Performance Capabilities
- Moves up to 88.3 gallons per minute
- Vertical lift up to 26 feet
- Ideal for emergency drainage situations
- Suitable for continuous pumping cycles
This level of performance makes the pump especially useful during flooding events, pool draining, and large-scale water transfer tasks.
Clean and Dirty Water Switching Capability
One of the standout features of this model is its ability to automatically switch between clean and dirty water discharge. The pump can safely handle solids up to 1/5 inch, reducing the risk of clogs and motor damage.
Benefits of Dual Water Handling
- Suitable for rainwater, wastewater, and effluent
- Handles debris without frequent maintenance
- Ideal for basements and outdoor environments
- Reduces downtime caused by blockages
This versatility allows the pump to adapt to changing conditions without requiring manual adjustments.
Automatic Float Switch Operation
The automatic float switch allows the pump to operate independently, activating when water levels rise and shutting off when water is removed. This is especially important for flooded basements and cellars where continuous monitoring is not practical.
Float Switch Advantages
- Prevents unnecessary motor operation
- Reduces energy consumption
- Protects against dry running
- Provides hands-free operation
For users who need continuous pumping, the float can be fixed to enable manual mode, allowing uninterrupted operation.
Manual Mode Flexibility
In addition to automatic operation, the PHLEX PRO pump offers a manual mode. When the float switch is secured, the pump runs continuously as long as it remains submerged.
This mode is particularly useful for:
- Draining large pools
- Emptying tanks or reservoirs
- Irrigation and water transfer
- Controlled continuous discharge
The ability to switch between modes enhances the pump’s versatility.
Safety and Thermal Protection
Safety is a critical consideration for high-powered submersible pumps. This model includes several built-in protections to ensure safe operation.
Safety Features
- Internal thermal overload protection
- Automatic power cut-off if overheating occurs
- Protection against dry running
- Sealed motor design for electrical safety
These features help prevent motor damage and extend the pump’s operational life. The manufacturer recommends not using the pump in water exceeding 35°C to maintain safe operation.
Removable Base and Easy Maintenance
Maintenance is simplified by the removable base design, which allows users to clean the intake area without disassembling the entire pump.
Maintenance Benefits
- Easy removal of debris and sediment
- Reduced risk of clogging
- Extended pump lifespan
- Faster post-use cleaning
This feature is especially useful when the pump is used in dirty water or outdoor environments.
Cord Length and Usability
The pump includes a long power cord, allowing easy placement in deep pits, flooded basements, or pools without needing extension cords.
Cord Advantages
- Easier retrieval from deep water
- Flexible placement options
- Reduced need for additional accessories
This adds convenience and improves safety during operation.
Noise Levels and Operating Comfort
Despite its high power output, the PHLEX PRO pump operates at a reasonable noise level for its class. When submerged, water helps dampen sound, making it suitable for use in residential environments without excessive disruption.
Energy Efficiency
While delivering high flow rates, the oil-free PSC motor is designed for efficient energy use. The automatic float switch further reduces unnecessary runtime, helping keep electricity consumption under control.
For emergency or occasional use, energy costs remain reasonable given the pump’s output capacity.
Wide Range of Applications
This pump is designed for versatility across many water management scenarios.
Common Applications
- Flooded basement and cellar drainage
- Swimming pool and spa draining
- Garden pond maintenance
- Rainwater and wastewater removal
- Aquarium and tank drainage
- Irrigation and water transfer
Its ability to handle both clean and dirty water makes it suitable for indoor and outdoor use.
Installation and Setup
Setup is straightforward and does not require specialized tools.
Basic Setup Steps
- Attach the discharge hose to the 1-1/2 inch outlet
- Submerge the pump fully in water
- Tilt slightly to release trapped air
- Plug into a standard electrical outlet
Once installed, the pump can operate automatically or in manual mode depending on user needs.
Durability and Expected Lifespan
With proper use and routine cleaning, the PHLEX PRO 1HP pump is built to provide long-term service. Its sealed construction, thermal protection, and debris-handling capability contribute to dependable performance over time.
Advantages and Limitations
