Pool volume, DEP turnover rate, pump HP sizing via TDH, filter sizing, and FL energy code
FL DEP CHAPTER 64E-9 COMPLIANTUse Volume tab to calculate required GPM, or enter directly.
TDH Quick Estimate: Typical residential = 40–60 ft. Commercial = 50–80 ft. Add 10 ft for each 100 ft of pipe run, 5 ft per 90° elbow, 10 ft for heater, 5 ft for filter, 15 ft for slide/waterfeature.
From Volume tab result.
Florida Statute 553.909 / F.A.C. 61G15-30.003: Effective January 1, 2021, all new pool pump installations in FL for pools with ≥1 HP pump require variable-speed pumps (VSP). This applies to both residential and commercial pools.
VSP energy savings: Running at 1,750 RPM instead of 3,450 RPM reduces energy use by up to 70% (affinity law: power ∝ RPM³). Typical savings: $600–$1,200/year for FL residential pools.

On this page, Florida pool pump sizing estimates run about $600-$1,200, depending on home size, materials, and project scope. Use the calculator above for a Florida-specific estimate.
Pricing depends on the size and layout of your home, the materials and fixtures you choose, your Florida region and local labor rates, and permit fees. Work that is more complex or harder to access generally costs more.
In Florida, minor maintenance may be DIY, but anything beyond that generally calls for a licensed plumber, and many jobs require a permit and inspection. When a permit, gas work, or your main water or drain lines are involved, hire a Florida-licensed plumber.
It depends on the cause and your specific policy. Sudden, accidental damage is more often covered than gradual wear-and-tear or maintenance - confirm the details with your insurer.
Timelines depend on scope - many routine jobs take a few hours to a day, while larger projects run longer. Your licensed plumber can confirm after assessing your home.
