Pool Cover Pump Guide: How to Choose, Use, and Troubleshoot the Right Pump for Your Pool: Types of Pool Cover Pumps: Which One Do You Actually Need? Automatic Submersible Pumps These are the "set it and forget it" option. A float switch or sensor detects water accumulating on your cover and kicks the pump.<\/p>\n<\/section>\n\n
Best for:<\/strong> Homeowners who travel, areas with unpredictable weather, anyone who doesn’t want to babysit their pool cover.<\/p>\n\n Watch out for:<\/strong> Cheaper auto pumps sometimes have unreliable sensors. Spend more than $35 to avoid frustration.<\/p>\n\n The Little Giant 577301 Automatic Pool Cover Pump<\/a> runs 1,200 GPH and has solid reviews for reliability. It’s the pump I recommend most often for typical residential pools.<\/p>\n\n You plug it in when needed, unplug when done. Simpler mechanics mean fewer things to break. But you have to remember to use it.<\/p>\n\n Best for:<\/strong> Budget-conscious buyers, people who are home frequently, backup pumps.<\/p>\n\n Watch out for:<\/strong> If you forget to turn it on before a storm, you’ll come home to a sagging, damaged cover.<\/p>\n\n These aren’t specifically designed for pool covers but can work in a pinch. They’re typically more powerful (2,000+ GPH) but bulkier and not designed to handle the shallow water depths on covers.<\/p>\n\n Best for:<\/strong> Homeowners who already own one for other purposes.<\/p>\n\n Walk around your covered pool. Water naturally collects at the lowest spot\u2014this is where your pump goes. For covers that sag in the center, that’s usually near the middle. For covers with a slight slope toward one side, place the pump there.<\/p>\n\n Attach a standard garden hose to the pump outlet. Run the hose to a drainage area away<\/em> from your pool. You don’t want to pump water right back toward the pool deck where it’ll seep under the cover.<\/p>\n\n Place the pump flat on the cover, intake screen facing down. Some pumps include a base plate\u2014use it. This prevents the pump from tipping and ensures the intake stays submerged as water levels drop.<\/p>\n\n Plug the pump into a GFCI-protected outdoor outlet. Never use extension cords rated lower than the pump’s amperage (check the pump label\u2014most need 15A-rated cords). For automatic pumps, you’re done. For manual pumps, wait until you have 1-2 inches of water before turning on.<\/p>\n\n Pro tip:<\/strong> Run the pump before the first heavy rain to confirm it works. Nothing worse than discovering a dead pump during a downpour.<\/p>\n\n GPH (gallons per hour) determines how fast your pump removes water. Too low, and water accumulates faster than it drains. Here’s the math:<\/p>\n\n A 20×40 foot pool cover that collects 1 inch of rain holds approximately 500 gallons of water<\/strong>. A 600 GPH pump removes this in under an hour. But during a heavy storm dropping 2+ inches per hour, that same pump can’t keep up.<\/p>\n\n Rule of thumb:<\/strong> Take your cover’s square footage, divide by 100, and multiply by 75. That’s your minimum GPH for moderate conditions.<\/p>\n\n Double these numbers if you live somewhere with frequent heavy rainfall or rapid snowmelt.<\/p>\n\n Check these first:<\/strong><\/p>\n Still nothing?<\/strong> The motor may be burned out. Pumps left running dry (even for 10-15 minutes) can overheat and die. Time for a replacement.<\/p>\n\n This is almost always debris clogging the intake screen.<\/p>\n\n For areas with heavy debris, consider the Wayne WAPC250 Automatic Cover Pump<\/a>, which has a larger intake screen designed for leaf-heavy environments.<\/p>\n\n For automatic pumps, this usually means:<\/p>\n The water level is right at the sensor threshold. This wastes electricity and wears out the motor. Add a platform under the pump to raise it slightly, or adjust the sensor if possible.<\/p>\n\n A well-maintained pool cover pump lasts 5-8 seasons. A neglected one dies after 1-2 years.<\/p>\n\n Monthly during cover season:<\/strong><\/p>\n At season end:<\/strong><\/p>\n People ask this all the time. Here’s the short version:<\/p>\n\n Pool cover pumps<\/strong> are designed for shallow water (1-3 inches) on horizontal surfaces. They have low-profile intakes and auto-shutoff to prevent dry running.<\/p>\n\n Sump pumps<\/strong> are designed for deep water in pits\/basins (6+ inches). They’re more powerful but won’t work well on a pool cover because they need deeper submersion to prime.<\/p>\n\n Can<\/em> you use a sump pump on your pool cover? Technically yes, but you’ll damage it running dry. Stick with a pump designed for the job.<\/p>\n\n Most residential pool cover pumps draw 50-120 watts. Running a 100-watt pump for 4 hours costs roughly $0.05-0.08 (at average electricity rates of $0.12-0.15\/kWh).<\/p>\n\n Over a 6-month cover season with average usage (maybe 20 hours total runtime), you’re looking at $2-4 in electricity. Not exactly budget-breaking. The cover you’re protecting cost $300-800. The pump pays for itself by extending cover life even one extra season.<\/p>\n\n Not all leaves are created equal.<\/p>\n\n Fine debris (pollen, silt, dust):<\/strong> Clogs mesh screens gradually. You won’t notice until flow drops significantly. Clean screens bi-weekly during heavy pollen season.<\/p>\n\n Large leaves:<\/strong> Block intake rapidly but visibly. Easy to clear but needs frequent attention. Look for pumps with raised or protected intakes.<\/p>\n\n Twigs and acorns:<\/strong> Can jam impellers entirely. If your pool is under oak or walnut trees, invest in a pump with an external debris basket you can empty without touching the pump itself.<\/p>\n\n The Superior Pump 91250 Cover Pump<\/a> handles debris well and is priced affordably for homeowners dealing with heavy leaf fall.<\/p>\n\n Affiliate disclosure:<\/strong> As an Amazon Associate, Pool Chemical Calculator may earn from qualifying purchases.<\/p>Manual Submersible Pumps<\/h3>\n\n
