Is Your Garbage Disposal Telling You Something?
Most homeowners don't think about their garbage disposal until it stops working — often at the worst possible time. The truth is, most disposals last 8 to 12 years, and when they start jamming frequently, leaking, making grinding noises, or just can't keep up, it's usually more cost-effective to replace than repair.
At Maxwell Plumbing, we'll give you an honest read on what's going on before recommending anything. Sometimes it's a simple fix. Sometimes a new unit is the smarter call. We'll tell you which — and why.
Whether it's a quick repair for a rental unit or a full upgrade for your kitchen, we'll get it done right the first time.

Buyer's Guide
Which Horsepower Is Right for You?
Garbage disposals are rated by horsepower (HP) — and the difference matters more than most people realize. Here's a plain-English breakdown of what each level gets you.
Best for
Light use — single person or couple, soft food scraps only. Least expensive upfront but jams more easily and won't handle fibrous or hard foods.
e.g. InSinkErator Badger 1
Best for
Average households of 2–4 people. Handles most everyday kitchen scraps well. Good balance of price and performance for most homes.
e.g. InSinkErator Badger 5, Moen GX50C
Best for
Larger families or frequent cooks. Handles tougher scraps like chicken bones, corn husks, and fibrous vegetables with less risk of jamming.
e.g. InSinkErator Evolution Compact, Moen GX75C
Best for
Households that cook a lot, entertain often, or have had repeated jamming issues. Rarely clogs, runs quieter, and tends to last longer with heavy use.
e.g. InSinkErator Evolution Excel, Moen Host Series
Not sure which HP is right for your household? We'll help you figure it out at no charge. We work with InSinkErator and Moen — two of the most reliable brands on the market — and we'll make a recommendation based on your usage, not our margin. Read our full garbage disposal guide →
