(The DOE Rule)The federal rule governs pumps and motors that makers build and sell, not pumps already in your yard. The sources cited here do not order owners to replace a working pump.

Texas freezes are short, so full closing is usually not needed. Consider winterizing if a long hard freeze is forecast, if power may fail, or if your equipment cannot circulate water on its own.Oct 21, 2026](https://marinapool.multisites.ai/post/close-your-pool-in-north-texas) - [Euless·3 minEuless Drought Stages Explained for Pool OwnersEuless follows the combined Tarrant Regional Water District reservoir level.

Check the screen, then call a pro.Oct 21, 2026](https://marinapool.multisites.ai/post/freeze-guard-not-working-pool) - [Grapevine·3 minGrapevine Fourth of July Pool Prep Checklist for HostsGrapevine's July 4 fireworks show over Lake Grapevine started at 9:30 p.m. in 2026, and Lake Grapevine parks charged $20 per vehicle.

Mustard algae is yellow-brown, shows up in shade, and returns after brushing. Black algae forms dark raised spots on plaster and resists chlorine. Pink slime is bacteria, not algae. Identify the type first, because each needs a different plan.Oct 21, 2026](https://marinapool.multisites.ai/post/green-black-mustard-algae-differences) - [Water care·4 minHard Water and Calcium Scale on Pool Tile in Tarrant CountyScale is calcium that comes out of the water and sticks to tile, surfaces and equipment.

Empty baskets often.Oct 21, 2026](https://marinapool.multisites.ai/post/pool-pollen-leaves-filter-clogging) - [Repair·4 minPool Filter Pressure Too High: What It MeansHigh filter pressure means water is meeting more resistance than normal. Compare the gauge to your own clean baseline. When it rises 8 to 10 psi above that number, clean or backwash the filter. If pressure stays high after cleaning, check closed valves, worn media and damaged parts.Oct 21, 2026](https://marinapool.multisites.ai/post/pool-filter-pressure-too-high) - [Repair·4 minPool Heater Repair or Replacement: Cost and Decision GuideAngi reports a national average of $476 for pool heater repair (page updated October 5, 2026) and $3,100 for installation (updated September 15, 2026).
