Buyer's Guide

What to Look for in a Garbage Disposal

Horsepower Requirements

Match power to household size. 1/2 HP suits 1-2 person apartments. 3/4 HP handles 3-4 person families. 1+ HP tackles heavy use and tough waste from large households or frequent cooking. Overpowering wastes money; underpowering causes jams.

Grinding System Material

Stainless steel components resist rust and corrosion, lasting years longer than galvanized steel. Anti-jam features automatically reverse grinding direction when stalling, preventing clogs. Look for stainless impellers and grinding chambers for maximum durability.

Mount Type Compatibility

EZ Mount systems install tool-free in minutes but require specific sink flanges. 3-Bolt mounts fit traditional installations but need more assembly. Check your current setup before buying—replacing like-for-like saves hours of plumbing work.

Noise Level Ratings

Premium units use sound insulation and anti-vibration mounts to operate below 65 decibels. Economy models often exceed 75 decibels—noticeably louder. Consider noise if your kitchen is open-concept or near living spaces.

Size and Clearance

Slim Line models measure under 7 inches wide, fitting tight cabinets with plumbing obstacles. Standard units need 8+ inches of horizontal space. Measure twice: account for drain lines, filters, and storage items that share the space.

Warranty Coverage

American Standard offers 2-5 year warranties depending on model. Premium units include in-home service promises. Economy models carry limited parts-only coverage. Longer warranties indicate manufacturer confidence in motor and grind component longevity.

Our Testing Process

How We Test Plumbing

🥩
Grinding Performance
We fed each disposal chicken bones, fruit pits, coffee grounds, vegetable peels, and eggshells to measure grinding speed and jam resistance. Timed cycles revealed real-world power differences.
🔊
Noise Measurement
Sound meter recorded decibel levels at 12 inches during operation. We tested with and without insulation to compare acoustic performance across price points.
🔧
Installation Test
Two plumbers and one DIY homeowner installed each unit, timing the process and documenting tool requirements, instruction clarity, and mounting system efficiency.
🔄
Jam Resistance
Intentionally overloaded each disposal with fibrous celery, potato peels, and corn husks to trigger anti-jam features. Counted manual resets required per model.
💧
Leak and Durability
Ran continuous 30-minute cycles with water to stress-test seals and motor heat management. Inspected internal components for wear after 100 cycles.
💰
Value Assessment
Compared price-per-horsepower, warranty length, feature set, and long-term reliability predictions to determine true cost of ownership over five years.
Frequently Asked Questions

Plumbing — FAQ

What horsepower American Standard disposal do I need for a family of four?
A 3/4 HP model like the 10-US-AS-7-SL handles typical family waste. Upgrade to 1.25 HP if you cook frequently or dispose of tough scraps like bones and corn cobs.
Are American Standard garbage disposals better than InSinkErator?
American Standard matches InSinkErator's build quality while often costing less per horsepower. Both use stainless steel grinders; American Standard's Slim Line offers space advantages InSinkErator lacks.
Can I install an American Standard disposal myself?
Yes. EZ Mount models install tool-free in 30-60 minutes with basic plumbing knowledge. 3-Bolt mounts need wrenches and plumber's putty but remain DIY-friendly. Always disconnect power first.
How long do American Standard disposals last?
With proper use, 8-12 years is typical. Stainless steel models resist rust longest. Running cold water during operation and avoiding non-food items maximizes lifespan.
What's the difference between Slim Line and standard models?
Slim Line units measure 6-7 inches wide versus 8+ inches for standard. They fit tight under-sink spaces without sacrificing power or grinding capacity.
Do these disposals work with septic systems?
American Standard disposals are septic-safe when used properly. Limit grease and fibrous waste. Consider a 1/2 HP model for slower septic tank digestion rates.
Final Verdict

🏆 Bottom Line

The American Standard 1-1/4 HP Premium Slim Line earns our top recommendation for its unmatched power-to-size ratio, commercial-grade stainless steel construction, and whisper-quiet operation that justifies every penny.

Choose the 1/2 HP economy model for apartments or light use; upgrade to 3/4 HP or higher for families, serious cooks, or anyone wanting a decade of trouble-free waste disposal.
