Frequently asked questions about the Syphons category
Syphons — what are sink syphons and why do I need one?
Syphons are plumbing devices fitted under a sink to ensure proper drainage and prevent sewer odours. The category includes bottle, pipe and flexible syphons in stainless steel and plastic, suitable for both kitchen and bathroom sinks.
What types of sink syphons are available and how do they differ?
Available syphons include bottle traps (compact for small sinks), pipe traps (stable drainage for heavy use) and flexible traps for non-standard connections. They differ by shape, dimensions and material — stainless steel for durability, plastic for cost-effective options.
What sizes do sink syphons come in and how to choose the right size?
Syphons are commonly for 1¼" (32 mm) and 1½" outlets; adapters and varying pipe lengths are available. Choose by sink outlet diameter (typically 32–40 mm) and the distance to the soil stack, opting for bottle traps for compact installs or longer pipe traps when needed.
Can you fit a sink syphon above a washing machine and which models suit?
Yes — compact bottle traps and low-profile pipe traps with a horizontal outlet suit installation above a washing machine to save space. Choose models with side outlets and adjustable pipe length for correct alignment.
What is a sink syphon with overflow and when do I need one?
A syphon with overflow suits sinks that have an overflow hole; it routes excess water away and prevents flooding. Choose a model whose overflow connection and outlet diameter (commonly 32 mm) match the sink.
What materials are sink syphons made from and what are the benefits?
Common materials are stainless steel and plastic (ABS). Stainless steel resists corrosion, is durable and looks modern; plastic is lightweight, cost-effective and easy to install.
Are stainless steel syphons suitable for kitchen and bathroom sinks?
Yes — stainless steel syphons are suitable for both kitchen and bathroom sinks because of corrosion resistance and durability. They are ideal for frequent use and exposed installations where appearance matters.
Which syphons are compatible with click-clack and pop-up sink plugs?
Syphons compatible with click-clack and pop-up plugs have matching outlet diameters and connections; the range includes models compatible with Nordline and Ravak plugs. Check compatibility by sink outlet size (typically 1¼"/32 mm) and plug mechanism.
Which syphon should I choose for a small kitchen sink?
For a small kitchen sink choose a compact bottle trap or a short pipe trap with a 32 mm outlet. They save under-sink space while providing effective drainage; stainless steel or matte ABS are common choices.
Which syphons suit bathroom sinks and are there special models?
Bathroom sinks can use pipe or bottle traps and syphons with overflow for sinks that have an overflow hole. The range includes low-profile and decorative models suitable for washbasins.
