A mechanism designed to increase the vertical reach of a drainage outlet. These typically consist of tubular components and connecting hardware, facilitating connection to existing drain pipes to elevate the drain’s discharge point. For example, this might be utilized when a washing machine drain hose does not adequately reach a standpipe, or when a sink drain needs to be connected to a higher-level plumbing fixture.
The importance of utilizing these components lies in their ability to prevent wastewater backflow and ensure proper drainage. Insufficient drain height can lead to siphoning, where wastewater is drawn back into the appliance or sink, creating unsanitary conditions. Historically, makeshift solutions were employed to address this issue; however, manufactured solutions offer greater reliability and adherence to plumbing codes, contributing to improved sanitation and appliance functionality.
