FAQ

Can a washing machine drain into a sink?

A washer drain hose is designed to release water into a utility sink, specifically not a kitchen sink. It is important to note that the sink should have sufficient depth to accommodate the water, and the hose requires an edge that is slim enough to securely attach to. It is worth mentioning that kitchen or bathroom sinks typically do not fulfill these requirements. This information was last updated on April 18, 2020.

Why does my washing machine drain into a sink?

When a washing machine pumps out a large amount of water, it can lead to a backup in the kitchen sink if there is any blockage in the drain pipe that is shared between the sink and the washing machine. This can be a common issue that homeowners may encounter. It is important to ensure that the drain pipe is clear and free from any obstructions to prevent this problem from occurring.

Why is my washing machine making my sink overflow?

Using an excessive amount of detergent in your washing machine can cause problems. It can lead to clogging and restrict the flow of water through the hose and drain line, which can result in overflow.
