To remove the dishwasher drain hose from the sink connection, locate the hose connected to the T-fitting or air gap underneath your kitchen sink and use pliers to disconnect it.
Removing your dishwasher's drain hose from its connection point at the sink is a common task, often required for replacement or plumbing work. The connection is typically made under the sink, either at a dedicated drain pipe fitting (often a T-fitting) or an air gap device on the countertop.
Step-by-Step Guide to Disconnecting the Hose
Disconnecting the old hose properly is crucial to avoid damaging other plumbing components or the dishwasher itself. Here’s how you can typically remove the hose connected near your sink:
1. Prepare the Area
Before you begin, it's wise to:
- Shut off the power to the dishwasher at the circuit breaker.
- Place a towel or small bucket underneath the connection point to catch any residual water that may drain from the hose.
2. Locate the Connection Point
Look underneath your kitchen sink. The dishwasher drain hose is usually a flexible corrugated or smooth hose that connects to:
- A T-fitting on the sink's drain pipe (before the trap).
- An air gap device mounted on the countertop, which then connects to the drain pipe.
3. Disconnect the Hose from the Fitting
As highlighted in the reference Disconnecting the Old Hose, the primary tool needed is pliers.
- Use pliers to disconnect the dishwasher's discharge hose from the T-fitting underneath the kitchen sink.
- The hose is typically secured with a clamp onto the fitting. This clamp could be a spring-style clamp that you squeeze open with pliers, or a screw-style clamp that you loosen by turning a screw with pliers or a screwdriver.
- Once the clamp is loosened or removed, gently twist and pull the hose end off the fitting. Be prepared for a small amount of water to drain out.
4. Remove the Hose
After the hose is disconnected from the under-sink fitting (or air gap), you can trace it back to the dishwasher. If you are replacing the hose, the reference suggests a useful trick: Tape the new discharge hose from inside the sink cabinet to the end of the old discharge hose. This allows you to pull the old hose out from the dishwasher side (often involves pulling it through cabinet holes), and it will guide the new hose into place simultaneously.
By following these steps, you can effectively remove the dishwasher drain hose from its sink connection point.
