Traps

Traps

Traps for under your kitchen sink, bathroom wash hand basin, shower and bath.

Because of its shape, a trap retains a small amount of water after the fixtures use. This water creates an air seal which helps stop smells making their way from the drain back into your house.

Bathroom wash hand basin wastes use a 32mm / 1-1/4 inch trap.
Kitchen sinks, baths and shower wastes use a 40mm / 1-1/2 inch trap.

** BSP thread sizes are measured a special way - have a look at our information page for more details **
