Dishwasher Connector Kit Guide for InSinkErator Disposals
A dishwasher connector kit is the small, inexpensive accessory that most homeowners forget—until installation day. This simple kit contains the fittings you need to hook your dishwasher’s drain hose into your garbage disposal. Without it, your dishwasher can’t properly discharge wastewater, which means leaks, drainage issues, and failed installs.
InSinkErator makes the process easier with universal dishwasher connector kits that fit almost every major dishwasher brand and every modern InSinkErator disposal series—Badger, Power, and Evolution. Whether you’re replacing an old disposal or installing a new dishwasher, this is the one accessory you should never skip.
In this quick micro-guide, we’ll cover exactly what a dishwasher connector kit does, when you need one, how to check compatibility, what’s included in the package, and the simple steps to install it. You’ll also get a direct link to the right universal kit so you don’t waste time guessing.
What Is a Dishwasher Connector Kit?
A dishwasher connector kit allows your dishwasher to drain through your garbage disposal instead of directly into the sink drain. The garbage disposal provides a secure outlet for your dishwasher’s drain hose and helps prevent backflow, clogs, and messy leaks.
A typical InSinkErator-compatible dishwasher connector kit includes:
- Hose inlet adapter – connects the dishwasher hose to the disposal’s inlet.
- Rubber connector sleeve – creates a snug, watertight seal.
- Hose clamp – secures the hose and sleeve to the inlet adapter.
- Basic mounting hardware – depending on the kit generation.
- Installation instructions – a simple, step-by-step guide.
These small parts work together to create a durable, leak-resistant connection between your dishwasher drain line and the InSinkErator disposal.

Do You Need a Dishwasher Connector Kit?
You need a dishwasher connector kit if any of the following are true:
- You are adding a dishwasher for the first time.
- You are replacing a garbage disposal that was previously connected to a dishwasher.
- You are switching dishwasher brands and the existing connector no longer fits properly.
- Your old connector is worn, cracked, leaking, or brittle.
- Your dishwasher hose and disposal do not match in diameter without an adapter.
If your dishwasher drains into your garbage disposal, you should assume you either need a new connector kit or should at least replace the old one. For InSinkErator models, the universal kit is designed to keep this decision simple: one kit, many compatible models.

|---|---|---|
| Badger Series | Fully compatible | Standard dishwasher inlet size across Badger 1, 5, 500, etc. |
| Power Series | Fully compatible | Updated grind design, but same inlet diameter for dishwasher connection. |
| Evolution Series | Fully compatible | All Evolution models support dishwasher connections via the kit. |
| Pro & Select Models | Generally compatible | Most models share the same inlet size as their consumer counterparts. |

What Comes in the Kit?
Most InSinkErator-style dishwasher connector kits include everything you need to make a secure connection:
- Hose clamp – a stainless steel clamp to tighten the hose onto the inlet.
- Rubber connector sleeve – flexible and engineered to form a tight seal.
- Hose inlet fitting – the adapter that matches your dishwasher hose to the disposal inlet.
- Hardware – any screws or clips required by that specific kit design.
Nothing fancy, nothing overcomplicated—just a small kit that prevents big problems.
Step-by-Step: How to Install a Dishwasher Connector Kit
Installing a dishwasher connector kit is a straightforward DIY project for most homeowners. Here’s the short version.
1. Remove the Dishwasher Inlet Plug (New Disposals Only)
New InSinkErator disposals ship with a plastic plug in the dishwasher inlet. Place a screwdriver against the plug and tap it gently with a hammer until it pops into the grind chamber. Then reach inside the disposal (with power off) and remove the plastic piece.
2. Prepare the Dishwasher Hose
Slide the rubber connector sleeve over the end of the dishwasher drain hose. This sleeve will sit between the hose and the inlet adapter on the disposal.
3. Insert the Hose Into the Disposal Inlet
Push the hose and sleeve assembly firmly onto the dishwasher inlet port on the side of the disposal until it is fully seated. A snug fit is what you’re aiming for here.
4. Tighten the Clamp
Position the hose clamp over the rubber sleeve and use a screwdriver or nut driver to tighten it. The clamp should feel firm and secure, but avoid overtightening to the point of cutting into the rubber.
5. Run a Test Cycle
Turn the power back on, run the dishwasher on a short rinse cycle, and watch the connection area under the sink closely. If you see no leaks or drips, you’re good to go.
Signs Your Connector Kit Needs Replacing
Even a good connector kit won’t last forever. Replace your kit if you notice:
- Water puddles or moisture under the sink after running the dishwasher.
- Visible cracks, brittleness, or deforming in the rubber sleeve.
- Rusty or loose clamps that no longer tighten properly.
- A hose that feels loose or wobbly where it connects to the disposal.
- Odors or backflow around the disposal area after dishwashing cycles.
If you’re already installing a new disposal, it makes sense to replace the connector at the same time. It’s a low-cost part that helps prevent high-cost water damage.

Dishwasher Connector Kit FAQs
Do I always need a dishwasher connector kit with an InSinkErator disposal?
If your dishwasher drains into your garbage disposal, you should use a connector kit. It provides the proper adapter, seal, and clamp to prevent leaks and backflow. If you’re installing a new disposal or dishwasher, it’s smart to install a fresh kit at the same time.
Is the dishwasher connector kit universal for all InSinkErator models?
Most universal dishwasher connector kits are designed to fit the standard dishwasher inlet used on InSinkErator Badger, Power, Evolution, and many Pro models. Always confirm InSinkErator compatibility in the product description, but in most cases, one kit covers them all.
Can I install the connector kit myself?
Yes. For most homeowners, installing a dishwasher connector kit is a simple DIY project that can be done in under 10–15 minutes with basic tools. Just remember to turn off the power to the disposal before starting and test for leaks afterwards.
What happens if I don’t use a connector kit?
Without a proper connector kit, your dishwasher hose may not seal correctly to the disposal inlet. This can lead to slow leaks, sudden bursts of water under the sink, drainage issues, or wastewater backing up into the sink and dishwasher.
Should I replace the connector kit when I replace my disposal?
Yes. If you’re upgrading or replacing an InSinkErator disposal, it’s best practice to install a new dishwasher connector kit at the same time. The old rubber sleeve and clamp may be worn, and a fresh kit helps ensure a secure, leak-free connection.
