Elevating the top load washing machine drain hose serves a specific purpose: it prevents water from siphoning out of the machine during the wash or rinse cycle. Siphoning can occur when the end of the drain hose is positioned lower than the water level inside the washing machine or when it is allowed to lie flat on the floor. When this happens, gravity can cause water to flow out of the machine continuously, leading to inefficient washing and potential water damage.
By elevating the drain hose, you create a "trap" or a high point in the hose, which prevents water from freely flowing out due to gravity. Instead, the water remains inside the machine until it's time for the drain cycle to begin.
To effectively elevate the drain hose, you can secure it to a standpipe or a laundry sink that is positioned higher than the water level in the washing machine. This elevation helps maintain the proper water level inside the machine, ensuring efficient washing and preventing any potential water leakage.
It's crucial to follow the manufacturer's guidelines and recommendations when installing and positioning the drain hose to ensure the washing machine functions correctly and to prevent any water-related issues.
