Replace Your Pentair SuperFlo SF-N1-1-1/2A with the BLACK+DECKER 1.5HP Variable Speed Pump
Installation Compatibility
The B&D 1.5HP VS inlet is 7.625" versus the SF-N1-1-1/2A's 7.5" — a difference of just 0.125". A thin shim or minor union adjustment handles the offset. Both pumps use standard 2" unions, so no pipe cutting is needed. Most homeowners complete this swap in under an hour.
Energy Savings
Your Pentair SF-N1-1-1/2A is a single-speed pump that runs at full power every time it turns on. At typical electricity rates, that costs roughly $900 per year. The BLACK+DECKER 1.5HP VS pump runs at lower speeds for daily filtration — using a fraction of the energy — and ramps up to full power only when you need it (running the cleaner, heating, water features). Average annual operating cost: approximately $150/year. That's an estimated $750 in annual savings, meaning the pump pays for itself within the first year or two.
Why Variable Speed
Variable-speed pumps aren't just about saving money — they're better for your pool. Running at lower RPMs improves filtration (water passes through the filter more slowly, catching finer particles), reduces wear on your plumbing and equipment, and cuts noise dramatically. The U.S. Department of Energy now mandates variable-speed technology for new pool pump installations in most states. Upgrading now means you're ahead of the curve — and many utility companies offer rebates of $50-$200 for Energy Star certified VS pumps.
Warranty Comparison
Your Pentair SF-N1-1-1/2A came with a 1 Year Limited warranty that requires professional installation to be valid. The BLACK+DECKER 1.5HP VS Pump is backed by a 3 Year Factory Warranty — direct to you, the homeowner. No proof of professional installation required. That's 3x the coverage of your old SuperFlo, with fewer hoops to jump through.
