If you are choosing between the Badger 15SS and the Badger 900 garbage disposals, you are already looking in the right place for a dependable, budget-friendly kitchen upgrade. Both belong to the well-known Badger family, popular for simple installation, compact size, and reliable everyday grinding. This guide breaks down the differences in plain English, shows what really matters for first-time installers, and helps you pick the model that fits your sink, your cooking style, and your budget.
Understanding the Badger Family
Where the 15SS and 900 Fit In
The Badger line is designed for straightforward, no-frills performance. Models like the 15SS and the 900 are retailer-specific versions, which means exact specs can vary slightly depending on where you buy them. In practice, they sit in the same practical tier: compact, continuous-feed disposals aimed at everyday use. They are commonly paired with standard sinks, apartment kitchens, and family homes that want dependable grinding without luxury-level bells and whistles.
Why Retailer-Specific Models Matter
Some retailers carry exclusive versions with slightly different names, warranties, or included accessories. That is why you may see a model called “Badger 900” at one store and a very similar model with a different name at another. Always check the box or product label for details like horsepower, materials, and whether a power cord is included. Still, understanding the common differences will give you a strong head start.
Power and Performance
Horsepower: How Much Do You Need?
These two models typically live in the mid-power range for Badger disposals. Depending on the specific configuration sold by the retailer, you will generally find them in the 1/2 HP to 3/4 HP category. This is an ideal sweet spot for small to medium households that cook frequently but do not grind very tough scraps.
What this means in daily use: either model should handle fruit peels, soft vegetable scraps, cereal, small chicken or fish leftovers (no bones), and similar everyday waste. For heavy, fibrous, or hard scraps, you should still use the trash or compost, even with higher horsepower, to keep the disposal running smoothly for years.
Continuous-Feed Convenience
Both the 15SS and 900 are typically continuous-feed disposals. Turn the water on, flip the switch, and feed in small amounts of food as it runs. This is simple and quick compared to batch-feed units that use a stopper. Just be careful: only feed small portions at a time and keep water running the entire time to move ground particles through the drain.
Grinding Components and Durability
Stainless Steel vs Galvanized Steel
The “SS” in 15SS often indicates stainless steel grinding components, while many 900 configurations use galvanized steel components. Stainless steel typically offers better corrosion resistance and may keep its edge longer over years of use. Galvanized steel is cost-effective and perfectly fine for light to moderate use when you follow good disposal habits.
If you want a disposal you plan to keep for many years, and you are happy to spend a little more up front, the stainless steel components found in many 15SS versions can be a worthwhile upgrade. If you are outfitting a rental unit, a second kitchen, or you do not grind many scraps, a 900 with galvanized parts may offer better value.
What Users Notice Over Time
In normal home use, both models can last many years if you avoid tough scraps and keep them clean. Stainless steel may resist pitting and rust better, especially in homes with mineral-rich water or where the disposal sits unused for stretches. Regardless of material, prevent corrosion by running water during and after use, and by cleaning the chamber regularly.
Noise and Vibration
What to Expect from Badger-Level Sound
Badger disposals are not built with the premium sound insulation you find in higher-end lines. The 15SS and 900 will sound similar: a noticeable hum while grinding, a brief rattle when larger bits hit the plate, and reduced noise once food clears. If you are sensitive to noise or have an open-concept kitchen near living spaces, consider a thicker sink mat and be mindful of what you grind.
Easy Ways to Make Either Model Quieter
Make sure the rubber splash guard sits flat in the sink opening to absorb vibration. Keep the mount tightened evenly so the disposal does not wobble. Avoid overloading the chamber. Use cold water with a steady flow; this helps move food quickly, shortening run time and reducing noise overall.
Size, Fit, and Under-Sink Space
Compact Bodies, Standard Mounts
Both models are built with a compact profile compared to many high-end disposals. They typically use the InSinkErator-style quick-lock mount, which makes swapping from an older Badger or compatible unit very easy. If you are tight on space under the sink, measure the height from the sink drain to the base cabinet floor, and also check distance to nearby plumbing, a water filter, or pull-out bins.
Dishwasher and Septic Compatibility
Both models commonly include a dishwasher inlet that you can connect to a dishwasher drain hose after knocking out the plug in the disposal’s side port. For septic systems, a standard Badger disposal can be used if your system is properly sized and maintained. Some homeowners prefer to keep fibrous scraps and grease out of both the disposal and the septic tank for peace of mind.
Installation for First-Timers
What Comes in the Box
Packages often include the mounting hardware, sink flange, stopper, and splash guard. Some units include a power cord; others are sold without one for hardwiring. If your unit does not include a cord and you want a plug-in installation, buy a compatible disposal cord kit and follow the wiring instructions carefully.
Tools and Setup
You will need plumber’s putty or the manufacturer-recommended gasket for the sink flange, a screwdriver, channel-lock pliers, and possibly a bucket. Turn off power at the breaker. If replacing an existing unit, disconnect the drain trap and mounting ring, then remove the old flange and clean the sink opening.
Step-by-Step Overview
Secure the new sink flange with putty or gasket. Attach the mounting assembly under the sink. If using a power cord, wire it according to the manual, respecting hot, neutral, and ground. Hang the disposal on the mounting ring, rotate until locked. Connect the discharge tube to the drain, and attach the dishwasher hose if needed after removing the knockout plug. Tighten all connections, run water, and check carefully for leaks before powering on.
Maintenance and Odor Control
Weekly Care in Two Minutes
Run cold water before, during, and for 10–15 seconds after use. Once a week, drop in a few ice cubes and a small splash of dish soap, then run the disposal with water. This helps remove film on the grind chamber and the underside of the splash guard, which is a common odor source.
Deep Clean Without Harsh Chemicals
Lift the splash guard and scrub the underside with a small brush and dish soap. Rinse thoroughly. Avoid bleach and drain cleaners; they can damage seals and metal parts. Citrus peels are fine for a fresh scent, but grind them in small amounts with plenty of water.
Unjamming and Resetting
How to Handle a Jam Safely
If the disposal hums but does not grind, turn it off immediately. Unplug it or switch off the breaker. Use the included jam-buster wrench (or a compatible wrench) in the hex hole under the unit to gently rock the grinding plate back and forth until it frees. Remove any visible obstruction from the sink opening with tongs, never with your fingers. Restore power, press the red reset button on the bottom if it has tripped, then run water and test.
Preventing Future Jams
Feed small batches. Avoid hard items like bones, fruit pits, and shell fragments. Skip long fibrous peels (celery, corn husks), coffee grounds, and eggshells if your drain clogs easily. Never pour fats or cooking oil down the disposal; they solidify in pipes and catch other debris.
Warranty and Support
Know Before You Install
Warranty length for the 15SS and 900 can vary by retailer or by the components used. Stainless steel grinding parts (often found in the 15SS) may be paired with longer warranties in some configurations, while budget-focused models (often the 900) may come with shorter coverage. Check the product box, the manual, or the model sticker on the unit for the exact warranty period and service terms in your area.
Service Considerations
Look for in-home service coverage, which can save time if an issue arises. Keep your receipt and note the serial number during installation. Following the installation and use guidelines is crucial for a smooth warranty claim if you ever need it.
Price and Value
Upfront Cost vs Long-Term Savings
In many stores, the Badger 900 is positioned as a strong value choice, while the Badger 15SS can cost slightly more due to the stainless steel grinding components. If you plan to keep your disposal for many years and you run it often, the 15SS may repay the difference with longer-lasting components. If you are on a tight budget or outfitting a space with light to moderate use, the 900 often delivers all the performance you need at a lower price.
Total Cost of Ownership
A good installation (no leaks, properly supported plumbing), using cold water during operation, and routine cleaning are what really determine how long your disposal will last—often more than the model choice itself. In other words, either model can be a money-saver over time if you treat it right.
Feature-by-Feature Comparison
What Is Typically Similar
Both are compact, continuous-feed units designed for straightforward everyday grinding. Both usually use the same style quick-lock mount, fit standard sink openings, and allow dishwasher connection. Noise levels are broadly similar for this family, and installation steps are nearly identical.
Where They Tend to Differ
The 15SS commonly features stainless steel grinding components that resist corrosion and wear. The 900 often focuses on budget-friendly pricing with galvanized components. Warranty terms may differ depending on retailer and exact configuration. Price is typically the major practical separator, with the 15SS costing more and the 900 sitting as a high-value pick.
Which One Should You Choose?
Pick the Badger 15SS If
You want stainless steel grinding parts for better long-term durability. You run your disposal frequently and prefer to invest a little more up front. You plan to keep the home for many years and want a “buy once” approach for this appliance.
Pick the Badger 900 If
You need a reliable, budget-friendly disposal for normal household use. You are replacing a unit in a rental or a secondary kitchen. You want a straightforward install and do not need premium materials or advanced sound insulation.
Alternatives to Consider
For Quieter Operation
If sound is your top concern, look at premium lines with added insulation and anti-vibration mounts. They cost more, but the difference is noticeable in open-plan homes or if you often run the disposal while entertaining.
For Very Light Use
If you rarely use a disposal or have very limited space, a 1/2 HP compact model can save money and space. Just remember to feed smaller portions and avoid tough scraps.
Beginner Tips for Trouble-Free Ownership
Smart Daily Habits
Run cold water before and during grinding to keep fats solid so they can move out of the chamber. Keep the flow going for 10–15 seconds after turning the unit off to flush the drain. Cut larger scraps into smaller pieces and feed them gradually.
What to Avoid
Skip hard bones, fruit pits, shell fragments, fibrous husks, coffee grounds, and large amounts of starchy foods like mashed potatoes or rice, which can clump and clog traps. Never pour grease or oil into the disposal.
Quick Pre‑Purchase Checklist
Confirm the Details
Check the box or product listing for horsepower, grinding component material (stainless vs galvanized), included power cord or hardwire requirement, warranty terms, and overall height. Measure your under-sink space and verify dishwasher hookup needs. If you are replacing an older Badger, confirm that the mount matches; odds are, it will.
Plan the Install
Gather tools, plumber’s putty or the recommended gasket, Teflon tape for threaded connections if applicable, and a towel or small bucket. Set aside at least an hour for a careful, leak-free installation, especially if this is your first time.
FAQs
Will either model fit my sink?
Most likely yes, as both commonly use a standard sink opening and the quick-lock mount. Always measure height and check for interference with existing plumbing or storage.
Do I need a power cord?
Some units include a cord; others are meant to be hardwired. If you prefer a plug-in setup, buy a compatible cord kit and follow the wiring instructions. Always cut power at the breaker before working.
Can I use it with a septic system?
Yes, when the system is properly sized and maintained. To be cautious, limit grinding of tough scraps and grease, and follow local guidelines for septic care.
How do I keep smells away?
Clean the splash guard underside, run ice and a little dish soap periodically, and flush with cold water after use. Avoid letting scraps sit in the chamber without running the unit.
