InSinkErator Flexible Discharge Tube, FDT-OO
This flexible discharge tube is designed to connect an InSinkErator disposer’s discharge to the drain line with ease. It flexes and offsets up to two inches, and retracts or extends from 6 to 10 inches to accommodate tight or unconventional drain layouts. Best for homeowners updating standard 1-1/2″ drain plumbing without changing existing fittings. It’s explicitly not compatible with Evolution Series disposers, so verify your model prior to purchase.
Who it’s best for: Homeowners with InSinkErator disposers that are not part of the Evolution line and who need a simple, adjustable tube that fits existing plumbing without heavy modification.
Why selected: This option emphasizes compatibility within the InSinkErator ecosystem and offers practical flexibility for common kitchen layouts. The retractable length helps manage alignment without extra elbows.
Caution: Do not use with Evolution Series models. Ensure your discharge diameter matches the 1-1/2″ drain connection for a reliable seal.
6FT Dishwasher Drain Hose, 7/8 Inch ID
This heavy-duty rubber hose is a robust drain line option for dishwasher connections, featuring thick material and reinforced construction to resist kinking and withstand hot water. It measures 6 feet in length with a 7/8-inch inner diameter, making it a solid direct replacement for models requiring these dimensions.
Who it’s best for: Buyers seeking a universal, durable replacement hose that can handle frequent use and hot water without losing shape.
Why selected: Its reinforced construction and longer length provide flexibility in tighter under-sink spaces and ensure a steady discharge path from dishwasher to drain. Two stainless clamps aid secure installation.
Caution: This is a general-purpose drain hose, not a model-specific fit for every disposal. Confirm that the inner diameter and length match your setup before purchasing.
Plumb Pak PP855-71 Dishwasher Discharge Hose
This rubber hose from Plumb Pak offers a straightforward solution for dishwasher discharge connections. It comes with two clamps and features a 6-foot length, providing a reliable, ready-to-install option for standard setups. The rubber construction aids in durability and ease of handling during installation.
Who it’s best for: Those replacing a worn or failing dishwasher discharge line who want a simple, no-fruss option with included clamps for quick sealing.
Why selected: It’s a practical, budget-conscious choice for common kitchen configurations where a standard 6-foot hose with clamps suffices.
Caution: This is a general-purpose option; verify your hose diameter and clamp compatibility with your current fittings before buying.
Danco Flexible Garbage Disposal Discharge Tube (12013)
Danco’s flexible discharge tube targets a broad range of InSinkErator models, including Badger and Pro series, making it a versatile option for many installations. Its flexibility supports up to a 2-inch offset and extends from 6 inches to 10 inches, helping to align the disposer with a variety of drain configurations.
Who it’s best for: Homeowners with InSinkErator models or compatible OEM equivalents seeking a flexible, easy-to-fit discharge tube.
Why selected: The wide compatibility makes it a convenient choice for multi-model homes or replacements where the exact OEM fit isn’t guaranteed.
Caution: Some users may find bend management requires careful positioning to avoid kinks in tighter spaces.
Garbage Disposal Dishwasher Connector Kit
This connector kit provides a rubber-based solution with proper clamps to connect a dishwasher drain hose to a garbage disposal. The kit’s pliable material eases hose connections, and it includes two hose diameters to match different ends. It’s specifically designed to streamline installation when the disposal and dishwasher hoses require compatible joining components.
Who it’s best for: Those who need a flexible, easy-to-fit adapter kit that bridges dishwasher hoses to a disposal without custom fabrication.
Why selected: It offers a practical, no-fuss option for creating a secure connection in cramped under-sink spaces.
Caution: Check hose inner diameters before purchasing to ensure a correct match with existing hoses and clamps.
Buying Guide: Key Considerations For Garbage Disposal Discharge Hoses
What diameter is required?
Most standard disposals use 1-1/2″ drain connections. Verify your unit’s discharge diameter and your drain inlet to avoid leaks or fit issues. Flexible hoses offer easier alignment but must still seal securely at both ends.
Is compatibility with your disposer model important?
Some hoses are built specifically for InSinkErator or certain Badger/Pro models. If you own a non-standard model, prioritize universal or OEM-compatible options to minimize fit problems.
Flexibility vs. durability balance
Flexible discharge tubes help with alignment in tight spaces but can kink if bent too sharply. Durable rubber or reinforced hoses resist kinking and handle frequent use but may require careful routing to avoid sharp bends.
Clamps and installation hardware
Including clamps simplifies installation and reduces the risk of leaks. Always check whether clamps are included and if you need additional mounting hardware for your setup.
Maintenance and replacement considerations
Choose hoses with robust materials and corrosion resistance to extend service life. Consider a kit that includes replacement clamps for future maintenance.

Frequently Asked Questions
- What is the typical purpose of a garbage disposal discharge hose?
To connect the disposal’s discharge outlet to the home drain line, allowing wastewater to flow away from the unit into the plumbing system.
- Do I need clamps with a new discharge hose?
Yes. Clamps ensure a watertight seal at both ends and help prevent leaks, especially under pressure from hot water and disposal operation.
- How do I know which hose length to buy?
Measure the distance from the disposal outlet to the drain inlet, plus any needed slack for mobile or adjustable configurations. Longer hoses are easier to position but require routing space.
- Can I use a dishwasher hose as a disposal discharge hose?
Some hoses are interchangeable, but confirm diameter and compatibility with your disposal model before connecting to avoid leaks or improper fit.
- What are common signs of an unsuitable hose?
Frequent leaks, kinking, reduced water flow, or disconnection during operation indicate a hose that does not fit or is worn out.
- Is it better to choose a flexible hose or a rigid one?
Flexible hoses simplify alignment in tight spaces, but rigid hoses can be more durable in straightforward setups. Choose based on your under-sink layout and potential future changes.
