One appliance hose or two? Check the McAlpine WM2 trap layout before ordering

If you’re ordering a replacement trap under a kitchen sink, start by counting the appliance hoses that actually discharge there. A single horizontal nozzle can be the right layout for one appliance, while a second hose changes the parts you need to look for.

Identify the three connections separately

Take one photo that shows the sink waste above the trap, the waste pipe leaving it, and the appliance hose coming in from the side. McAlpine identifies WM2 as a 1½-inch sink trap with one horizontal domestic appliance nozzle. The Multifit compression connection is the waste outlet. The horizontal nozzle is a separate connection for the appliance hose.

Count hoses and check the space beside the nozzle

Trace each appliance discharge hose to its connection. If you have a washing machine and dishwasher, record where each hose goes. If both need to connect under the same sink, ask for a layout with the right number of dedicated inlets. Photograph the side clearance around the nozzle, including the cabinet wall or pull-out bin, so the installer can check the hose route before ordering.

Match the model and check the supplied parts

Read the reference on the old trap or packaging if available. Ask APM to confirm the supplied fittings and check the appliance maker’s discharge-hose instructions. Keep the waste pipe size, hose connection and nozzle count as separate notes when asking for a match.
