40mm 1½” Standpipe Appliance Trap for Washing Machine & Dishwasher
This 40mm 1½” Standpipe Trap provides a safe and compliant way to connect washing machine and dishwasher waste hoses to your household drainage system. The trap features a 75mm water seal depth as required by UK building regulations, effectively blocking foul smells from entering the utility room or kitchen while allowing high flow discharge from modern appliances. The vertical standpipe design ensures the appliance hose is held at the correct height to prevent back-siphoning, and the supplied rubber adaptor creates a tight seal on 19-23mm diameter hoses. Manufactured from durable white polypropylene, the trap resists heat, vibration, and harsh detergents used in wash cycles. The 40mm 1½” universal outlet connects directly to push-fit or solvent weld waste pipe, making it suitable for new installations and replacements. Ideal for use in kitchens, utility rooms, and integrated appliance housings.
