Yes, you can run your pool pump with a solar cover on. The pump will still circulate water effectively underneath the cover, and this is actually recommended for maintaining water quality.

Yes, you can absolutely run your pool pump with a solar cover on. In fact, running your pump while the solar cover is in place is recommended for optimal water circulation and chemical distribution. The cover won't interfere with your pump's operation, and the pump will effectively circulate water underneath the cover through your pool's return jets and skimmers.
Running your pool pump while the solar cover is on provides several advantages that many pool owners don't realize. The pump continues to circulate water through your filtration system, ensuring that chemicals remain evenly distributed throughout the pool. This is particularly important because the solar cover can create temperature variations in different areas of your pool.
The circulation also prevents stagnant water pockets from forming under the cover, which could lead to algae growth or chemical imbalances. Your skimmers will continue to pull water from the surface, while return jets push filtered water back into the pool, maintaining the same circulation pattern whether the cover is on or off.
When using a solar cover, adjust your pump schedule to maximize both energy efficiency and water quality. Run your pump during daylight hours when the solar cover is heating your pool water. This timing allows the pump to distribute the warmed water throughout the pool, preventing hot spots and ensuring even temperature distribution.
For most residential pools, running the pump 6-8 hours during peak solar heating hours (typically 10 AM to 6 PM) provides adequate circulation. If you have a variable speed pump, consider running it at lower speeds for longer periods while the cover is on, as you won't need the higher flow rates typically required for surface skimming when the cover is off.
Solar covers significantly impact your pool's chemical needs, making proper pump operation even more critical. The cover reduces chlorine loss from UV degradation by up to 95%, meaning your chlorine will last much longer. However, this also means you need excellent circulation to prevent chlorine from becoming concentrated in certain areas.
Test your water chemistry more frequently when using a solar cover, especially during the first few weeks of use. The reduced evaporation means you'll add fresh water less often, which can lead to higher total dissolved solids (TDS) over time. Your pump's circulation becomes crucial for distributing any chemicals you add.
Maintain your free chlorine (FC) levels according to your cyanuric acid (CYA) levels using the FC/CYA relationship. With a solar cover, you might find you need 30-50% less chlorine to maintain proper sanitizer levels. Always add liquid chlorine with the pump running to ensure immediate distribution throughout the pool.
Never enter the pool while the solar cover is on, even partially. This is a critical safety rule that applies regardless of whether your pump is running. Solar covers can create entrapment hazards, and the pump's suction adds an additional risk factor.
Ensure your pool's safety equipment, including pool alarms and safety covers, remain functional when the solar cover is in place. Some pool alarm systems may not work properly with solar covers, so verify compatibility with your specific equipment.
Check that your solar cover isn't blocking return jets or interfering with skimmer operation. The cover should float freely on the surface while allowing water to flow underneath. If you notice reduced flow from return jets, the cover might be positioned incorrectly.
Running your pump with a solar cover actually reduces strain on some equipment while potentially increasing it on others. Your pump basket and skimmer baskets will collect fewer leaves and debris with the cover on, reducing cleaning frequency. However, the reduced debris also means less natural water mixing, making your pump's circulation more important.
Clean your pool filter more frequently when using a solar cover consistently. The reduced natural evaporation and refilling means contaminants become more concentrated, potentially loading your filter faster than usual. Monitor your pressure gauge and clean the filter when pressure rises 8-10 PSI above the clean starting pressure.
Inspect your solar cover regularly for wear, especially around areas where return jets create water movement. The constant circulation can cause gradual wear on the cover material, and damaged sections can affect both heating efficiency and safety.
If you notice uneven heating despite running your pump, check that return jets aren't creating excessive turbulence that lifts sections of the cover. Adjust return jet direction slightly downward to maintain gentle water movement without disrupting the cover's contact with the water surface.
Should you experience difficulty maintaining proper chlorine levels with the cover on, increase your pump runtime rather than adding more chemicals. Better circulation often resolves chemical distribution issues more effectively than higher chemical doses.
If your automatic pool cleaner isn't working effectively with the solar cover, consider removing the cover during cleaning cycles, then replacing it afterward. Most robotic cleaners can operate under solar covers, but suction-side cleaners may struggle with the reduced surface access.
