Details

Removing an old washing machine or relocating a dishwasher frequently leaves you with a dangerous, open plumbing connection under the kitchen sink. For instance, the old appliance hose hooked directly onto a molded plastic spigot protruding from your sink trap. Once that hose is removed, waste water from the main sink basin will spray straight out of the open 48mm spigot whenever the tap runs. Furthermore, foul-smelling sewer gases will constantly seep out into your kitchen cabinets. Leaving an open drain lines is an unsanitary hazard that causes massive under-sink flooding.

Fortunately, this genuine McAlpine blanking cap and washer resolves these hazardous appliance disconnection issues immediately. This low-profile white cap screws straight onto the redundant 1.5″ BSP male thread, blocking the open path entirely. Thus, you do not have to purchase and install a brand-new sink trap assembly just to close off the branch. Additionally, the included heavy rubber washer compresses tightly into the base of the cap as you spin it on. Consequently, it creates a completely permanent, gas-tight seal that stands up to pressurized wastewater.
