What is this law?
The DOE Energy Conservation Standards for Dedicated-Purpose Pool Pump Motors is a federal law that requires most pool pump motors to be variable-speed starting September 29, 2025.
Does this law apply to me?
Yes. The U.S. Department of Energy’s (DOE) Energy Conservation Standards for Dedicated-Purpose Pool Pump Motors apply in all U.S. states and territories.
- Nationwide coverage – No matter where you live in the U.S., the rule applies.
- State rules may go further – Some states (like California and Florida) already had strict efficiency laws before the federal rule. In those cases, you’ll need to follow whichever law is stricter.
- Homeowners, pool pros, and businesses – Anyone replacing a pump or pump motor must comply.
What this means for you
- September 29, 2025 – Replacement pump motors ≥ 1.15 THP must be variable-speed.
- September 28, 2027 – The rule expands to motors 0.5 – 1.15 THP.
- Small motors (< 0.5 THP) must meet minimum energy efficiency requirements.
After these dates, replacing with a single-speed motor will no longer be legal.
Why this matters
- Lower energy bills – Variable-speed pumps can cut energy use by up to 80%.
- Quieter operation – Run at lower speeds for a much quieter pool.
- Longer lifespan – Less strain on the motor means fewer breakdowns.
- Nationwide compliance – Stay on the right side of federal law while saving money.
