The InSinkErator PRO 1250 is the pinnacle of food waste disposal performance, representing the highest standard in the PRO Series lineup. Designed for serious home chefs, busy households, and anyone who demands both power and quiet operation, this 1.25 HP continuous-feed garbage disposal combines cutting-edge engineering with a sleek, durable build. With advanced MultiGrind® technology, ultra-quiet SoundSeal® performance, and a 12-year in-home warranty, the PRO 1250 is more than just an appliance—it’s a long-term kitchen investment.
The PRO 1250 features InSinkErator’s most powerful residential motor—a single-phase, 1.25 HP Dura-Drive® induction motor that operates at 1,725 RPM. Built to handle even the toughest, most fibrous food scraps, this motor delivers consistent grinding performance day after day. Permanently lubricated upper and lower bearings ensure a smooth, maintenance-free operation, while the motor’s robust design guarantees a long service life.
With its continuous-feed design, the PRO 1250 allows you to add food waste while the unit is running, making meal cleanup faster and more efficient. Controlled via a wall switch, it offers the convenience of quick operation without interrupting your cooking flow.
Where standard disposals may struggle with fibrous or dense scraps, the PRO 1250 excels thanks to its 4-stage MultiGrind® system. This advanced grinding process pulverizes food waste into ultra-fine particles, drastically reducing the risk of clogs and helping to minimize odor buildup in your plumbing. This technology is especially effective on foods that can jam other disposals, such as celery, artichoke leaves, corn husks, and small bones.
As the quietest garbage disposal on the market, the PRO 1250 redefines what users can expect from in-sink appliances. InSinkErator’s SoundSeal® insulation reduces noise and vibration to a whisper, making it possible to run your disposal without interrupting conversations or disturbing the peace of your home. The Quiet Collar® sink baffle further minimizes sound, and it’s both removable and dishwasher safe for easy cleaning. Antimicrobial treatment on the baffle helps control odor and bacteria growth.
The grind chamber and components are made from corrosion-resistant materials and stainless steel to ensure longevity, even under heavy daily use. The premium build quality means fewer breakdowns, less maintenance, and a product that continues to look and work like new for years.
The PRO 1250 includes InSinkErator’s EZ Connect system, making it compatible with both plug-in and hardwired setups. The dishwasher drain connection allows seamless integration into your kitchen’s existing plumbing, and installation is straightforward for both professionals and skilled DIYers.
For homes using properly maintained septic systems, the PRO 1250 is a safe choice. Its MultiGrind® technology breaks down food particles into a fine slurry, minimizing the load on septic tanks.
Despite its incredible power, the PRO 1250 is remarkably efficient. It uses an average of just 1 gallon of water per person per day and 3–4 kWh of electricity per year. This balance of performance and sustainability makes it an eco-conscious choice for modern kitchens.
The PRO 1250 features automatic reset motor protection to safeguard against overloads. This means that if the disposal is jammed or overloaded, it will shut off automatically, protecting the motor from damage.
