Pro Tips

3/4 HP is the sweet spot for most households — 1/3 HP jams constantly, 1 HP is overkill. A $150-$250 3/4 HP disposal handles everything a typical family throws at it without jamming
InSinkErator and Waste King dominate for good reason — These two brands account for 90%+ of the market. InSinkErator is quieter, Waste King is cheaper. Both are reliable. Avoid no-name brands
DIY replacement saves $100-$250 in labor — If you're replacing an existing disposal (same mount type), it's a 30-minute DIY job. Just twist off the old one, twist on the new one, and reconnect the drain
Always run cold water while using the disposal — Cold water solidifies grease so it gets chopped up. Hot water melts grease, which then re-solidifies in your pipes and causes clogs
Never put these in a disposal — Grease/oil, fibrous vegetables (celery, corn husks), pasta/rice (expands), coffee grounds (accumulate), bones thicker than a chicken wing, and eggshells (myth — they don't sharpen blades)
Reset button fixes 90% of "broken" disposals — Before calling a plumber, check the reset button on the bottom of the unit and use an Allen wrench in the bottom socket to free jammed blades. Fixes most issues for $0

What You Need to Know

Garbage disposals are a $100-$400 investment that lasts 8-15 years and significantly reduces kitchen waste. Installation is straightforward for replacements ($100-$250 labor or DIY) but requires plumbing modification for first-time installations ($200-$500). The most common mistake: buying too small — a 3/4 HP mid-range disposal handles typical household use without jamming.
