Buying Guide for the Best Submersible Pool Pump For Draining
Choosing the right submersible pool pump for draining is all about matching the pump’s capabilities to the size of your pool and the particular draining needs you have. Whether you occasionally drain your pool completely, just need to lower the water level after heavy rain, or deal with typical maintenance, understanding key specifications will help you avoid underperforming pumps or overpaying for features you don’t need. Focus on how quickly the pump can move water, how deep your pool is, and the durability needed for your usage frequency.Flow Rate (Gallons Per Hour or Gallons Per Minute)Flow rate refers to the volume of water the pump can move in a given period, typically expressed in gallons per hour (GPH) or per minute (GPM). This is essential because it directly affects how fast you’ll be able to empty your pool. Lower flow rates (for example, under 1500 GPH) are suitable for small above-ground pools or minor drainage tasks, while higher flow rates (up to 4000+ GPH) are better for large in-ground pools or if you want to drain your pool quickly. Consider a pump with a flow rate that matches your patience and the size of your pool—higher rates get the job done faster, but may be unnecessary if you only drain occasionally.
Maximum Lifting Height (Head Height)Maximum lifting height, also known as head height, tells you how high the pump can move water vertically. This is important if you need to pump water up and out of a deep pool or if the drainage spot is higher than the pool edge. Pumps with a low head height (below 10 feet) work for shallow above-ground pools where water needs to be lifted just a short way, while deeper in-ground pools may require a pump with a higher head height (often 20 feet or more) to ensure efficient water removal. Match the lifting height to the depth of your pool and the elevation of drainage so the pump operates efficiently without straining.
Type of Material and DurabilityThe materials used in the pump's construction affect how well it holds up over time, especially when exposed to pool chemicals and outdoor conditions. Pumps made from thermoplastic or corrosion-resistant metals, like stainless steel, withstand harsh environments and pool water better than cheaper plastics. If you plan to use the pump frequently or leave it outside, prioritize more robust and chemical-resistant materials, while occasional users can compromise a bit here for lower weight or easier handling.
Intake and Discharge SizeThe size of the pump's intake and discharge ports determines the type and size of debris it can handle, as well as how fast the water can move through hoses. A larger intake helps prevent clogging if you're draining slightly dirty pools, and a bigger discharge port (like 1.5 to 2 inches) can move water faster than smaller ones. Choose according to your typical conditions: clean water and fine debris allow smaller ports, but if you expect leaves and grit, opt for a larger intake and discharge diameter, and pair the pump with appropriate hoses.
Automatic Shutoff/Float SwitchSome pumps come with an automatic shutoff or float switch feature, which turns off the pump when water levels are low. This protects the pump from running dry, which can cause damage. If you often walk away while draining or want a worry-free process, look for this feature for extra peace of mind. Manual shutoff works if you’re attentive or if you only use the pump under supervision, but automatic shutoff is helpful for convenience and pump longevity.
Ease of Use and PortabilityWeight, handle design, cord length, and hose attachments all factor into how easy it is to move and operate the pump. Lightweight pumps with sturdy handles and long cords are ideal if you’ll move your pump around frequently or need to reach distant power outlets. Consider both your strength and the layout of your pool area—choose features that make handling, storing, and setting up the pump easy for your situation.
