Astra Walker’s bottle traps and basin wastes provide reliable, sleek solutions for modern bathrooms. Key products include 32mm wastes suited for basins and 40mm wastes suited for baths, designed for durability, easy installation, and efficient water flow management.
While 32mm and 40mm may sound like they refer to the waste itself, these sizes actually correspond to the internal diameter of the pipe they connect to.
If you’re not sure which one you need, here’s a simple guide: 32mm Waste
– Suits standard bathroom basins
– Connects to 32mm pipe
– 1 1/4″ BSPP thread (approx. 41mm external diameter)
Need an Adaptor?
The Astra Walker A70.38.ADT adaptor is designed to convert a 1 1/2″ BSPP waste (e.g. A70.04) to a 1 1/4″ BSPP connection (e.g. A70.03), making it compatible with the A70.38 Bottle Trap.
What is BSPP?
BSPP stands for British Standard Pipe Parallel, referring to a straight (non-tapered) thread commonly used in plumbing.
