Recessed siphon for washing machine or dishwasher – a discreet and functional solution

This recessed siphon HL404 is a practical solution for draining water from a washing machine or dishwasher, allowing you to save space and maintain the aesthetics of the bathroom or laundry room. Designed with convenience in mind, both during installation and use, it combines functionality and durability.

Construction and installation

The siphon is designed for recessed mounting, which means that most of the elements are hidden in the wall or floor, leaving only the connection elbow and the stainless steel plate visible. This makes it perfectly fit into modern interior designs. The set includes a 3/4 inch (HL19) connection elbow, which facilitates connection to the existing installation. The stainless steel plate provides an elegant finish and easy cleaning. The siphon also has a removable siphon element in the form of a cassette, which facilitates possible cleaning or maintenance. The installation depth is from 65 to 115 mm, which ensures compatibility with various types of construction.

Application and benefits

The HL404 siphon is equipped with a backflow preventer, which protects the washing machine or dishwasher from backflow of dirty water. Additionally, it has a connection for mounting an air vent valve (HL902), which prevents the formation of a vacuum in the sewage system – especially important at a greater distance of the device from the downpipe. This solution ensures efficient drainage and minimizes the risk of drainage problems. Made of durable polypropylene (PP) guarantees long-lasting and trouble-free operation.
