Frequently Asked Questions

Q: Is this washbasin siphon trap compatible with standard bathroom sinks?

A: Yes. The 1-1/4 inch (32mm) threaded connection is the most common standard size for bathroom washbasins and is compatible with the majority of household bathroom sinks. Always verify your existing drain outlet size before purchasing.

Q: Can I cut the drain pipe to fit my under-sink space?

A: Absolutely. The drain pipe is designed to be trimmed to your required length, giving you full control over the fit. Combined with the 360° rotation feature, this makes it highly adaptable for small or unusually configured under-sink cabinets.

Q: How does the 70mm water seal prevent odours?

A: The water trap retains a constant column of water (70mm deep) inside the siphon body. This water acts as a physical barrier, blocking sewer gases and unwanted odours from travelling back up through the drain into your bathroom — a standard and effective plumbing technique used in homes worldwide.

Q: Is the silicone seal replaceable if it wears out?

A: The threaded connection design allows for straightforward disassembly, making it possible to inspect and replace the silicone seal if required. We recommend checking the seal periodically as part of routine bathroom maintenance.
